Fabrication Weldability of Hardox 500 Wear-resistant Steel and Its Application

Hardox 500 is a kind of carbide-free wear-resistant steel with the microstructure of martensite-bainite.The properties of the welded joint and the microstructure transformation of this steel were investigated.The fabrication weldability of this steel was examined.The results indicate that Hardox 500 wear-resistant steel has good welding processablility and the low alloy electrode in strength range of 500-600 MPa can be used to weld this steel.This steel plate has been successfully applied.
