The rust of ASTM A179 seamless steel pipe parts is soaked in 440 ~ 460 deares C molten zinc solution, which makes the zinc coating on the surface of the steel plate attached to the surface of the steel plate, playing a role in corrosion protection. This is an effective method of corrosion of metals. The main features are as follows:
(1) ASTM A179 seamless steel pipe manufacturer covers the surface of cold-drawn seamless steel pipe with a dense layer and a dense zinc layer. Can avoid cold drawn seamless steel tube matrix and corrosion liquid contact, protect the steel matrix from corrosion. In the general atmosphere, the surface of zinc layer forms a thin and dense surface of zinc oxide, which is not easily soluble in water, so the steel matrix plays a protective role. If the atmospheric zinc oxide and other components produce insoluble zinc, corrosion protection effect will be better.
(2) ASTM A179 seamless steel pipe has a strong wear resistance due to the combination of strong zinc-iron mixture.
(3) the surface of ASTM A179 seamless steel pipe.
