Pipeline steel plays an important role in pipeline transportation. How many types of astm a656 grade 80 chemical composition, pipeline steel are there? At present, pipeline steel can be divided into the following four categories according to microstructure. First, pearlitic pipeline steel. The basic components of pearlitic pipeline steel are carbon and manganese, generally speaking, the content is 0.10% - 0.20%, and the manganese content is 1.30% - 1.70%. It is generally produced by hot rolling or normalizing heat treatment process. Second, acicular ferrite pipeline steel. Third, martensitic pipeline steel. Fourth, tempered sorbite pipeline steel.

In order to improve the astm a656 grade 80 chemical composition corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main astm a656 grade 80 chemical composition coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking astm a656 grade 80 chemical composition sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.
