40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel steel coil SPA H high quality is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching. When the hardness is HB174～229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.
