501 stainless steel and 304 which is better

AISI 501(S50100) stainless steel belongs to high temperature bolting steel, the implementation of the standard: ASTM A194/A194M-2020

AISI 501(S50100) has a good resistance to oxidation at about 650 degrees Celsius, has good thermal strength below 600 degrees Celsius, and has good vibration damping and heat conduction, which is widely used in the It is widely used in steam turbines. Used as reheat steam pipe, oil cracking pipe, boiler hanger, steam turbine cylinder bushings, pump parts, valves, piston rods, high-pressure hydrogenation equipment parts, fasteners and so on.

AISI 501 (S50100) chemical composition is as follows:
