Grade Overview

Introduction & Overview — Stainless Steel 409-75 Plates

The SS409-75 Plate, also referred to as AISI 409 75 plate, is a ferritic steel plate that is primarily made of chromium alloy. It offers good oxidation resistance, moderate resistance to corrosion and exceptional weldability. This grade is commonly used in situations where strength, cost efficiency and resistance to high temperature oxidation are needed. The basic principle of SS 409-75 Plate is founded on its ferritic structure that provides stability under heat stress as well as resistance to scaling at high temperatures. The chromium content forms an oxide protective layer on the surface, delaying further oxidation and increasing the life of the product.
