The purpose of nitriding is to increase the surface hardness of the steel and improve its wearing properties. This treatment takes place in a medium which gives off nitrogen. In nitriding, nitrogen diffuses into the steel and forms hard, wear-resistant nitrides. This results in an intermetallic surface layer with good wearing and frictional properties. Our screws and barrels will get the hardness at surface about 900Hv~1000Hv, the depth of nitride layer will into 0.6mm and 0.7mm of nitride steel Nitriding i
