BAIJIAN - Third party testing organization
Testing methods for automotive metal parts: mechanical properties、 hardness、 Charpy impact、 chemical composition、 metallographic structure、 cleanliness、 coating thickness、 adhesion、 sealing quality、 corrosion resistance、 and other commonly used metals in automobiles include black and non-ferrous metals. Black metal steel plates are divided into three types according to their properties: ordinary thin steel plates、 high-quality thin steel plates、 and coated thin steel plates; According to its rolling method、 it is divided into two types: hot-rolled steel plate and cold-rolled steel plate; According to its thickness、 it can be divided into two types: thin steel plate and thick steel plate. Non ferrous metal sheets refer to sheets of metals and their alloys other than steel and iron、 which have different colors and physical and chemical properties. Due to long storage time or poor storage、 the surface of metal steel may rust. Before use、 rust removal treatment should be carried out、 including mechanical rust removal and chemical rust removal&Nbsp
