Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 317 Flanges, which are hardened machining and becomes more difficult and probably impossible. Stainless Steel 317 Slip On Flanges is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. It’s very high carbon content of 1.0 % is responsible for these characteristics, which make Stainless Steel 317 Threaded Flanges particularly suited to such applications as ball bearings and valve parts. Stainless Steel UNS S31700 Weld Neck Flanges have lower attainable hardness but slightly higher corrosion resistances, where chips are tough and stringy so chip breakers are important.

Corrosion resistance is generally lower than the common austenitic Stainless Steel 317 Blind Flanges, and their useful operating temperature range is limited by their loss of ductility at sub – zero temperatures and loss of strength by over-tempering at elevated temperatures. In the annealed condition, Stainless Steel 317 Socket Weld Flanges is relatively easily machined; approximately the same as for high speed steel.
The great benefit of Stainless Steel 317 Lap Joint Flanges (and of other precipitation hardening grades of stainless steel) is that they are generally supplied in the solution treated condition, in which they are just machinable, and then can be age hardened to achieve quite high strengths. This aging treatment in Stainless Steel 317 Ring Joint Type Flanges is so low in temperature that there is no significant distortion.
