431 Stainless Steel Data Sheet

Out of heat treatment comes the high mechanical properties.

431 stainless steel data sheet. 431 has great impact strength at a high hardness level. Description carpenter stainless type 431 is designed to provide improved corrosion resistance and toughness in a quench hardenable stainless steel. Consequently it is suited to bolts and shaft applications e g. Technical data sheet alloy 431 is the most corrosion resistant of the martensitic grades.

431 high hardness and toughness grade primarily for shafting 440a 440b 440c very high hardness grades used in cutting tools precipitation hardening stainless steel 630 17 4ph high strength shafting grade note that some of these stainless steel grades are commonly referred to by designations that are registered trademarks. 431 stainless steel has been designed to improved corrosion resistance and toughness properties than other 400 stainless grades especially in a quench hardenable stainless. 431 is the most corrosion resistant of the martensitic grades. It has been used for parts such as aircraft fasteners and fittings and should be considered for structural members exposed to marine atmosphere.

Available forms of stainless 431 are seamless pipe welded pipe seamless tube welded tube bar wire sheet plate forgings pipe fittings and flanges. It features good corrosion resistance to aqueous solutions of oxidizing acids most organic acids and organic salts. 431 would work well in marine environments as well as in aerospace applications such as aircraft fasteners and fittings. 431 is a high chromium low nickel high hardenability martensitic stainless steel with high strength and good corrosion resistance as generally supplied hardened and tempered in the tensile range 850 1000 mpa condition t brinell range 248 302.

Nuts and bolts pump and propellor shafts marine hardware and laboratory equipment. 431 is a high chromium low nickel high hardenability martensitic stainless steel with high strength and good corrosion resistance as generally supplied hardened and tempered in the tensile range 850 1000 mpa condition t brinell range 248 302 characterised by very good corrosion resistance in general atmospheric corrosive environments good resistance to mild marine and industrial atmospheres resistant to many organic materials nitric acid and petroleum products coupled with high. Due to alloy 431 s excellent tensile and torque strength and good toughness it is used in structural parts that are exposed to marine atmosphere also for aircraft fasteners and fittings. It has excellent tensile and torque strengths and toughness.

Aisi 431 can be supplied as steel plate sheet round steel bar steel tube pipe steel stripe steel billet steel ingot steel wire rods. 431 is a type of martensitic stainless steel with good balance between its strength and toughness.
