SAPH440 Automotive Grade Hot Rolled Carbon Steel Coil 1.6-12mm Thickness Chassis Frame Structural Parts
製品の説明
The SAPH440 automotive structural hot rolled carbon steel coil complies with JIS G3113 and is engineered for vehicle chassis rails, cross members, suspension arms and reinforcement brackets that must absorb repeated dynamic loads. This grade combines a minimum tensile strength of 440 MPa with good formability, allowing complex press-formed geometries without cracking while retaining the stiffness required for crash safety performance.
