Product Description

JSC590R (B410LA) 590MPa Micro-Alloyed Steel

Engineered for High-Performance Suspension Components in Demanding Environments

 

Product Overview

JSC590R is a thermo-mechanically processed micro-alloyed steel optimized for automotive suspension systems. With balanced strength-ductility and superior fatigue resistance, it enables 25% weight reduction in trailing arms and torsion beams while exceeding 10^7 fatigue cycles under extreme cornering loads.
