Paper Title:
Microstructure and Properties and Wear Resistant of Carbide Free Bainitic Casting Steel
  Abstract

The microstructure and properties and wear resistant of carbide free bainitic casting steel were studied by using of OM, TEM, XRD, impact test and abrasion test. The results showed that after normalizing at 1080°C and tempering at low temperature the microstructures consisted of bainitic ferrite, remaining austenite and no carbides with combination properties of strength and toughness. After tempering at 250°C the tensile strength was 1667MPa, Rockwell hardness HRC49 and impact ductility AKU 36J, respectively. This new casting steel by normalizing at 1080°Cand tempering at 200°C had better wear resistance than that of high manganese steel under the same test conditions, moreover the reason was analyzed.
