GB 20CrMnTi gear steel is GB standard Alloy Carburizing Gearing steel, GB 20CrMnTi properties is a chromium, manganese, titanium alloy steel specification. 20CrMnTi is equivalent with others standard bearing/Gearing steel, gearing steel

characteristics of hardened steel alloy tool steel, good carburizing heat treatment process and the performance of the steel at ≤960 ℃ fine grain structure, commonly used in long-term heating carburizing temperature, the grain grew no tendency little residual austenite after quenching, therefore, the steel has high strength and wear resistance, excellent cutting performance, the main performance and 20CrMnTi and 20CrNi steel similar. Tensile strength σ ≥1080MPa, yield strength σ ≥885MPa, elongation δ ≥10%, 45% reduction of swelling, impact toughness (impact toughness) α ≥69J / cm, hardness ≤207HB, blank sample size to 15mm.
