431 stainless steel is a stainless steel quality that includes both chrome and nickel. 431 quality stainless steel is a kind of stainless steel which can be made very high resistance to breakage together with heat treatment. This stainless steel grade is also called 4057 or 1.4057. Standard production of this stainless steel quality is post-production heat treatment, and our company's 431 (1.4057) quality materials are sold as QT800 or QT900 heat treatment.
1.4057 conducts stainless heat well and is suitable for polishing. 431 quality materials have a good surface structure even in hot environment. 431 grade stainless steel is also called 1.4057 quality stainless steel and it can be shown in many media as stainless steel X17CrNi16-2.
431 grade stainless steels are used in bolt and nut construction, propeller shafts, pump shafts, mixer bars, marine equipment and laboratory equipment.
