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.

S20910 stainless steel provides a combination of good corrosion resistance and strength not found in any other commercial material available in its price range. This austenitic stainless steel has corrosion resistance greater than that provided by types 316 and 316L, plus approximately twice the yield strength at room temperature in the annealed condition. In addition S20910 stainless steel has very good mechanical properties at both elevated and sub-zero temperatures a well as outstanding cryogenic properties. And, unlike many austenitic stainless steels, 22-13-5 stainless steel can be heavily cold worked to enhance its yield strength and remain non-magnetic. Please note that we have a minimum order value of £10,000.

Stainless steel is an iron alloy, containing a minimum of 10.5% chromium. It is often combined with other alloying elements such as nickel, nitrogen, and molybdenum to create the corrosion-resistant product used in many applications. Hamilton Precision Metals offers a diverse range of 300 and 400 series stainless steels.

HPM® 455 is a precipitation heat treatable martensitic Stainless Steel. The composition provides a good combination of corrosion resistance and heat treated strength favorable for fatigue applications. The material is well suited for demanding spring devices The alloy has reasonably good forming characteristics in the annealed temper considering that it has a hardness of RC30. A significant radius is useful when bending is necessary in a fabrication. Cold working prior to the precipitation hardening treatment can drive finish strength up to 270,000 PSI (0.2% offset yield strength). The alloy retains a good strength through 800°F (Approx. 70% of room temperature). Resistance to stress – corrosion cracking is optimized by heat treating at 950°F. The overall corrosion resistant to normal atmospheric is equal to SS 430 with no staining. The alloy can be welded by resistance and inert gas shielded techniques. It also is suitable for brazing using a flux when possible.

SS 17/4 PH® is a precipitation hardenable Martensitic stainless steel with high strength, and good corrosion resistance. This makes it perfect for use in metal diaphragms, for both aerospace sensors and burst discs. It is easily heat treated from the annealed temper. The corrosion resistance of the alloy is comparable to SS 302. It is heat treated at 900° F/1 Hour for highest strength. Other thermal treatments can be utilized to provide greater toughness and improved formability. Joining of the alloy is accomplished by the usual methods that are effective for stainless steel. Available Sizes: SS 17/4 PH® is available from Hamilton Precision Metals as strip product in thicknesses from 0.001” to 0.050” (0.0254 mm to 1.27 mm) and widths up to 12.0” (304.8 mm). The material conforms to AMS 5604, ASTM A693 and UNS S17400.

SS 17/7 PH® is a precipitation hardenable stainless steel that is formable and also capable of meeting high strength requirements. It is utilized in applications that require both high strength and good corrosion resistance. The alloy is classified as semi-austenitic to distinguish the soft phase (austenite) available for ease of forming from the high strength phase (martensite) usually achieved by heat treatment. The alloy can be formed from the annealed temper but due to a rapid work hardening rate may not be deep drawn without intermediate annealing. It is joined by most arc and resistance methods used for stainless steel. It should not be fusion welded unless shielded by inert gas to prevent oxidation of aluminum.

SS 301 is an austenitic Chromium-Nickel stainless steel capable of attaining high strength with moderate cold working. The combination of high strength and good ductility makes it suitable for numerous mechanical switches as well as surgical instruments, metal stampings and electronic and computer spring components.. The alloy is readily formed in the annealed temper. Ductility decreases with increased cold rolled strength but not to the degree that would occur with SS 302. It is not recommended for deep drawing. SS 301 can be welded by all conventional processed except oxy-acetylene. The weld should not make contact with electrolytes to prevent intergranular corrosion. SS 301 is resistant to atmospheric corrosion and is additionally resistant to mildly corrosive mediums. The combination of narrow strength bands and close thickness tolerance provided by Hamilton Precision Metals is the key to repeatable response characteristic in spring and switch applications.

SS 302 is an austenitic Chromium-Nickel stainless steel offering the optimum combination of corrosion resistance, strength and ductility. These attributes make it a favorite for many mechanical switch components, as well as surgical instruments. The alloy is readily formed in the annealed temper. SS 302 may be joined by all commonly used brazing and welding methods including oxyacetylene. Caution should be used to avoid cooling slowly through the range of 900° to 1600°F where carbide network could form and reduce corrosion resistance. This characteristic is diminished due to the typically low carbon composition of Hamilton’s SS 302. The corrosive resistance to acids is generally very good with the exception of halogen acids.
