Microstructure and Properties of Non-Quenched Prehardened Steel for Plastic Mould with 700 mm Thickness

摘要：

　　The non-quenched prehardened steel for plastic mould with 700 mm thickness (NQP700)has been developed in order to save energy and shorten the producing cycle.Microstructure and properties of the NQP700 steel are studied.The results show that microstructure of the NQP700steel block is bainite distributing uniformly through the whole section,whose hardness fluctuation is not more than ±1.5HRC.Its polishing ability and pattern etching properties satisfy the needs of plastic mould,and it has better machinability.
