Surgical Implant 316L is a double melted stainless steel, regarded as a medical grade, this stainless steel is melted to achieve high levels of purity and cleanliness. It has excellent resistance to both general and intergranular corrosion, and pitting and crevice corrosion. The double melting allows for superior surface finish. Surgical implant 316L Stainless Steel is our most commonly sold medical stainless steel. Beyond removing impurities, this process, in combination with the unique nickel and chromium content of 316, tends to facilitate the formation of the surface chromium oxide layer that makes stainless steel corrosion resistant. There is some belief that surgical implant 316L forms a more substantial surface layer, and that this plays a strong role in protecting the host body from reactions to the nickel content of the material.

316LN (UNS S31653) is a low-carbon, nitrogen-enhanced version of Type 316 molybdenum-bearing austenitic stainless steel. The Type 316 alloys are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Type 304. They also offer higher creep, stress-rupture and tensile strength at elevated temperature. The nitrogen in Type 316LN adds additional resistance to sensitization in some circumstances. The nitrogen content of Type 316LN stainless steel also provides some solid solution hardening, raising its minimum specified yield strength compared to Type 316L stainless steel. Like Types 316 and 316L, the Type 316LN alloy also offers good resistance to general corrosion and pitting/crevice corrosion. Please note that we have a minimum order value of £10,000.

Grade 316 is the standard molybdenum-bearing grade, second in overall volume production to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. Grade 316L, the low carbon version of 316 and has very high immunity from sensitization (grain boundary carbide precipitation). It is extensively used in the oil and gas and chemical industries for its cost effective corrosion resistance and ease of fabrication. There is commonly no appreciable price difference between 316 and 316L stainless steel. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures. Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures. Please note that we have a minimum order value of £10,000.

A flexible and cost-effective way of connecting tubes to each other reliably and stably. RK Rose+Krieger developed the precision-cast stainless steel tube connectors specially for heavy loads and impact-resistance. The high-strength tube connectors are resistant to high temperatures and corrosion, and are engineered for dynamic loads. An electrochemical passivation – the tube connectors are electropolished in a final working step – makes them more resilient and resistant to acids than elements made of untreated stainless steel. As a result they are particularly resistant to cleaning with aggressive cleaning agents or hot water from high-pressure cleaners, and ideally suitable for use in packaging machines or for feeding technology in plants in the chemicals industry. Stainless steel clamp connectors are tough. Stainless steel clamps are particularly important for users working in the fields of chemical and food technology.

347 (UNS S34700/1.4550) is a fully austenitic niobium stabilised stainless steel. The addition of Niobium reduces the creation of carbide precipitation in service between 430 to 900 degrees C and during welding processes and increases the mechanical strength of the material. This grade has good resistance to oxidation and corrosion along with good creep strength and can be used at temperatures where carbide precipitation may occur in non-stabilised grades e.g., 304. It is used principally in aerospace exhaust manifolds and engine components, chemical processing equipment running at high temperatures and in nuclear processing piping. Please note that we have a minimum order value of £10,000.

The microstructures inside duplex stainless steels are approximately 50 per cent austenite and 50 per cent ferrite, and consequently duplex products share the physical properties of both ferritic and austenitic grades. Duplex stainless steels are resistant to the cracking caused by chloride stress corrosion in austenitic grades, and have improved resistance to localised corrosion. This family of stainless steels has roughly twice the yield strength of their counterpart austenitic grades . Higher hardness values provide better wear resistance for high precision tubes. Duplex stainless steel tubes have high hardness and wear resistance propertiesDuplex steels are easily welded and formed, similar to austenitic grades. Depending on chromium, nickel and molybdenum content, duplex stainless steels are divided into four main categories: lean duplex, duplex, super duplex and hyper duplex. Please note that we have a minimum order value of £10,000.

6 Mo (UNS S31254) is a super austenitic stainless steel with a high level of molybdenum and nitrogen, providing high resistance to pitting and crevice corrosion as well as high strength compared with conventional austenitic stainless steels such as 316L.

316Ti (UNS S31635) is a titanium stabilised version of 316 molybdenum-bearing austenitic stainless steel. The 316 alloys are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as 304. They also offer higher creep, stress-rupture and tensile strength at elevated temperature. High carbon Alloy 316 stainless steel can be susceptible to sensitisation, the formation of grain boundary chromium carbides at temperatures between approximately 900 and 1500°F (425 to 815°C) which can result in intergranular corrosion. Resistance to sensitisation is achieved in Alloy 316Ti with titanium additions to stabilise the structure against chromium carbide precipitation, which is the source of sensitisation. This stabilisation is achieved by an intermediate temperature heat treatment, during which the titanium reacts with carbon to form titanium carbides.

It is the quality with the best malleability feature among the austenitics. Its malleability capability is around 78% and it is named as the automat of stainless steel. Although the sulfur (S) addition improves its malleability, it also reduces corrosion resistance (lower than 304) and weakens its formability, it is especially not suitable for straight bending. Despite sulfur, its toughness degree is the same as 304.

UNS NO8904, commonly known as 904L, is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of AISI 316L and AISI 317L are not adequate. The addition of copper to this grade gives it corrosion resistant properties superior to the conventional chrome nickel stainless steels, in particular to sulphuric, phosphoric and acetic acids. However, there is limited use with hydrochloric acids. It also has a high resistance to pitting in chloride solutions, a high resistance to both crevice and stress corrosion cracking. Alloy 904L performs better than other austenitic stainless steels due to the higher alloying of nickel and molybdenum. The grade is non-magnetic in all conditions and has excellent formability and weldability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures. Please note that we have a minimum order value of £10,000.

The welding process is one of the core ways in which we manufacture precision tubes. Our high-quality tubing starts off as a flat strip of metal. The strip is formed into a tube through a series of rollers and the join, also called the seam, is then welded together. Welded Processes Special non-destructive testing methods – including eddy current, ultrasonic and pressure testing - are used to ensure a consistent weld. Just like with seamless manufacturing, welded tubes can be drawn down by plug drawing or sinking. This method can be used to create very long lengths of coiled tube, these can also be measured during coiling using a laser measurement. The main welded tube manufacturing processes used are strip welding and cold drawing, but other important processes in between, or at the end of the drawing process, include Please note that we have a minimum order value of £10,000.

The high precision seamless tubes manufactured at Fine Tubes begin their journey as seamless tube extrusions, in a range of different sizes. This material is reduced in size several times until it gradually reaches the exact specifications our customers require. Each time we perform a reduction process, the tube needs to be cut, cleaned and heat treated before the next one can commence. Please note that we have a minimum order value of £10,000.

At Superior Tube we're proud of the way our precision tubes are used to help save lives. Welded and seamless tubes we've manufactured are used for specialized products across the medical device industry. For instance, transcatheter aortic valve replacement (TAVR) is a promising new treatment for patients with severe aortic stenosis - a narrowing of the heart valve - who are not ideal candidates for traditional open-heart surgery. Because the replacement valve can be implanted using techniques that are far less intrusive than open-heart surgery, patients with TAVR usually experience a much more rapid recovery than they normally would. On the other hand, more traditional valve replacement surgery might employ our pericardial stented tissue heart valves. These implants help blood flow naturally and offer excellent hemodynamic performance. They are designed for optimal performance and long-term durability.
