Chemical composition of welding process of hardox 400 equivalent AISI

The effect of elements in welding process of HARDOX 400, wear-resistant steel plate on high-temperature temper embrittlement can be divided into: (1) Impurity elements such as phosphorus, tin, antimony and so on that cause the high-temperature temper brittleness of the wear-resistant steel plate. (2) Alloy elements that promote or slow down the brittleness of high temperature tempering in different forms and degrees. Chromium, manganese, nickel, silicon, etc. play a promoting role, while molybdenum, tungsten, titanium, etc. play a retarding role. Carbon also plays a catalytic role.
