253MA Stainless Steel Plate Heat Resistant up to 1150°C, Ideal for Heat Treatment Equipment & Exhaust Systems

Products Specification

1. Introduction

253MA® is a patented, nitrogen-enhanced austenitic stainless steel engineered by Outokumpu for extreme thermal cycling environments (up to 1150°C/2100°F). Its cerium micro-alloying forms self-healing oxide layers, delivering superior oxidation/spalling resistance versus 310S/309S grades. Ideal for cost-sensitive replacements of nickel alloys in corrosive, high-stress thermal applications.
