20CrMnTi alloy round bar,20CrMnTi steel bar,20CrMnTi steel Mechanical properties

20CrMnTi alloy round bar,20CrMnTi steel bar,20CrMnTi steel Mechanical properties
20CrMnTi Alloy steel round bar is hardened steel, hardened steel is usually a carbon content of 0.17% -0.24% of mild steel. Multi-car manufacturing gear, is the hardenability carburizing steel Cr Mn Ti steel, high hardenability, hardenability in ensuring the situation, especially those with higher low temperature impact toughness.
