Flat Washers (Flat) Stainless Steel A2 - DIN 433

The Hygienic DESIGN fastening system was specially developed for use in food processing facilities. Special attention was paid to the cleaning-optimised geometry and a surface finish of Ra ≤ 0.8 µm. The quick and easy installation due to a pre-installed sealing washer rounds off the overall package.

Alloy 17-4 PH is a chromium-copper precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. 17-4PH Stainless Steel combines high strength, hardness (up to 572°F / 300°C), and moderate corrosion resistance. Alloy 17-4 PH withstands corrosive attacks better than any of the standard hardenable stainless steels and is comparable to Alloy 304 in most media. The alloy is subject to crevice or pitting attack if exposed to stagnant seawater for any length of time, although it is corrosion resistant in some chemical, petroleum, paper, dairy and food processing industries(equivalent to 304L grade). Mechanical properties can be improved (high strength and superior corrosion resistance) when precipitation hardened from Condition A to one of the Condition H tempers. We supply 17-4 PH in the H1150D condition. This is double aged at a temperature between 1140° F and 1160° F for 3.75 hours to 4.
