AISI 410S Plates / SS 410S Plates
AISI 410S (UNS S41008) is a low carbon, Non-Hardening modification of Alloy 410 (UNS S41000) the general purpose 12% chromium martensitic stainless steel. The low carbon and a small alloy addition minimize austenite formation at high temperatures which restricts the alloys ability to harden. 410S remains soft and ductile even when rapidly cooled from above the critical temperature. This non-hardening characteristic helps prevent cracking when the alloy is exposed to high temperatures or welded. 410S is completely ferritic in the annealed condition. It exhibits adequate corrosion resistance similar to 410 and good oxidation resistance.
Grade 410S / 1.4000 ferritic stainless steel is a lower carbon version of grade 410. Unlike the martensitic grade 410 this grade is NOT hardenable.
IT ALSO CONFORMS TO ASTM A240M-19 TYPE 410S/ASME SA240M TYPE 410S. MATERIALS IS ANNEALED IN ACCORDANCE WITH REQUIREMENT AS LAID IN CLAUSE NO 15.4.1 OF ASTM A480/A480M-20/ASME SA-480M 2023 SECII,PARTA. YS-0.2% OFF SET METHOD, Inspection Certificate Complies To EN-10204-3.1. NACE MR0103 - 2016 & NACE MR0175 / ISO 15156 - 2015.
