Grade Overview

Introduction & Overview — IRS350 CR Plate (AISI)

IRS350 CR Plate, also referred to as AISI IRS350 CR Plate, is a cold-rolled structural steel plate known for its excellent strength, formability, and surface finish. "CR" stands for Cold Rolled, indicating that the plate undergoes cold reduction after hot rolling, which enhances dimensional accuracy and mechanical properties. The performance of the IRS350 CR Plate is derived from its cold rolling process — after hot rolling, the steel is cold reduced at room temperature, which refines the grain structure and improves tensile and yield strength, enhancing surface smoothness, flatness, and thickness tolerance.

Composition Analysis

Metallurgical Characteristics of IRS350 CR Plate

Each element in IRS350 CR plays a precise role in delivering strength, formability, and cold-forming performance.

Fe
Iron
Base metal providing structural strength and ductility.
C
Carbon
Enhances hardness, wear resistance, and tensile strength; critical for cold-forming performance.
Mn
Manganese
Improves toughness, hardenability, and resistance to deformation during forming.
Si
Silicon
Contributes to strength and helps maintain stability during heat treatment.
P
Phosphorus
Controlled residual element; excessive amounts reduce ductility and toughness.
S
Sulfur
Controlled to improve machinability without affecting toughness.
