Carburizing
Operation method: put infiltration medium carbon steel, heating to 900 ~ 950 degree and heat preservation, the steel surface to obtain a certain concentration and the depth of carburized layer.Objective: to improve the steel surface hardness, wear resistance and fatigue strength, heart of toughness condition remain the same.Application points: 1. Used for carbon content is 0.15% ~ 0.25% of low carbon steel and low alloy steel parts, general carburized layer depth is 0.5 ~ 2.5 mm;2. Must be carried out after carburizing quenching, martensite surface, and to achieve the purpose of carburizing.
