Tensile strength
Tensile strength is the main performance of the material after quenching. Generally, the tensile strength of 420J2 after quenching can reach more than 1400, and the unquenched material is about 900.
Anti-rust performanceThe anti-rust performance of martensitic steel after quenching is better than that of unquenched materials, mainly because after the carbon chromium decomposes, the carbon dissolves in the matrix, and the chromium element strengthens the anti-rust properties. Chromium is an element that plays a decisive role in rust prevention in 400 series stainless steel. Due to the presence of carbon chromium compounds before quenching, the actual chromium element that is responsible for rust prevention is about 2% lower than the actual content. After quenching, the chromium element content can increase by 1%. above.
