This specialized steel is engineered for superior performance, featuring a precise composition that delivers a remarkable minimum yield strength of 700 MPa. Through a controlled Quenching and Tempering heat treatment, it achieves an outstanding balance of high strength and exceptional toughness. This process ensures the material can withstand significant impact and stress without compromising its integrity, making it far more resilient than conventional steel plates.
