Grade Overview

Introduction & Overview — IRS450 CR Plate (AISI)

IRS450 CR Plate, also referred to as AISI IRS450 CR Plate, is a high-strength cold-rolled structural steel plate designed for applications requiring enhanced load-bearing capacity and durability. The "CR" (Cold Rolled) process improves surface finish, dimensional accuracy, and mechanical strength compared to hot-rolled products. IRS450 CR Plates are known for their higher yield strength than IRS350 grades, making them suitable for demanding structural and fabrication applications.
