Enhance your manufacturing with our premium SAE1075 Steel Band
Our product is a high-carbon spring steel strip, processed via Cold Rolling followed by Hardening and Tempering (Quenched & Tempered) . This heat treatment process relieves internal stresses from rolling while achieving uniform hardness across the strip, eliminating distortion during your processing.
Why choose our Cold Rolled Hardened and Tempered Steel Strips?
SAE1075 Grade Guarantee: Strict chemical composition control ensures excellent fatigue resistance .
Superior Surface: Offered in Bright/Polished, Blue (Tempered), or Oxidized/Black finish.
Precision Tolerances: Suitable for high-speed stamping and forming.
Edge Condition: Available in slit round edge or square edge to protect tooling.
