510L shearing blade is currently a high-end steel product used for automotive longitudinal beams. Its chemical composition consists of C ≤ 0.20%, Mn 1%–1.6%, and Si ≤ 0.55%, with a tensile strength ranging from 510–630 MPa.

Due to the material's properties, shearing blades must meet exceptionally high standards for both toughness and strength. Common failure modes for these blades include plastic deformation (slumping), abrasive wear, and cracking, leading to extremely high blade consumption rates.

To address these challenges, our company utilizes custom-ordered low-carbon (C ≤ 0.38%) ESR (Electroslag Remelting) ultra-refined H13 raw materials from leading steel mills. Our specialized process includes:

Precision Forging

Spheroidizing Annealing

Oil Quenching at 1040°C

Four or more cycles of thorough tempering

Field testing by end-users confirms that the steel-shearing volume per blade has more than doubled. This achievement has delivered significant economic benefits, contributing tangibly to cost reduction and efficiency for our customers.
