SWRCH40K, a high-carbon steel grade, is widely recognized for its exceptional cold heading properties and tensile strength. With a carbon content of 0.37-0.44% and manganese levels up to 0.60%, this material achieves 15% higher formability than standard ASTM specifications. As demand grows in fastener manufacturing, over 68% of global automotive suppliers now prioritize SWRCH40K for critical components.
The alloy's optimized chemical composition enables:
Post-processing capabilities allow surface roughness values as low as Ra 0.8μm, meeting precision requirements for aerospace fasteners.
