1.4462 (super duplex stainless steel, X2CrNiMoN22-5-3) is a high-strength, well-balanced duplex stainless steel, while 1.4547 (super austenitic stainless steel, 254 SMO, X1CrNiMoCuN20-18-7) is a highe

1.4547 offers far superior corrosion resistance compared to 1.4404, particularly against chloride-induced pitting, crevice corrosion, and stress corrosion cracking; its PREN ~42–45 allows reliable use

A182 F44 is a super austenitic stainless steel, commonly known by its UNS number S31254, European standard 1.4547 (or X1CrNiMoN20-18-7), and trade names (such as 254 SMO); it is a high-molybdenum allo

ASTM A312 UNS S31254 grade stainless steel contains high levels of chromium (19.5-20.5%), nickel (17.5-18.5%), molybdenum (6.0-7.0%), and nitrogen (0.18-0.25%), resulting in a pitting resistance equiv

UNS S31254 is a super austenitic stainless steel, commercially known as 254 SMO. Depending on the product form, it has several equivalent ASTM grades, with ASTM F44 being the most direct equivalent (

1.4547 material (European standard) is a high-alloy austenitic stainless steel, equivalent to UNS S31254 (American standard), commonly known as 254 SMO (brand name/generic name), ASTM F44 (for forging

Stainless steel 1.4547 (254 SMO, UNS S31254) is a high-alloy austenitic stainless steel containing significant amounts of chromium, nickel, molybdenum, and nitrogen, as well as copper. The alloy's co

1.4057 QT800 is a martensitic stainless steel (X17CrNi16-2 / AISI 431) heat-treated to a minimum tensile strength of 800 MPa, with equivalents being AISI 431, UNS S43100, and SS2321, known for high st
