Why there are quality defects on the surfaces of S355MC automobile structure steel strip

The company now has S355MC automobile structure steel strip oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other de

The company now has S355MC automobile structure steel strip oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than S355MC automobile structure steel strip 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

The S355MC automobile structure steel strip, thin steel plates are more convenient for cutting. Since the thickness of the thin steel plate is basically below 4mm, it is very easy to construct during cutting, which also reduces the work intensity of the construction personnel and speeds up the work efficiency of cutting. There are different materials for thin steel plates, such as ordinary carbon steel, high-quality carbon structural steel, alloy structural steel, carbon tool steel, stainless steel, spring steel, silicon steel for electrical engineering, etc..

Weathering steel is characterized in that the alloy composition and weight percentage content. The chemical composition C≤0.12, Si: 0.25 ～ 0.75, Mn: 0.20 ～ 0.50, P: 0.07 ～ 0.15, S≤0.03, Cu: 0.25 ～ 0.55 , Cr: 0.30 ～ 1.25, Ni≤0.65, and the rest are Fe and trace impurities. Weathering steel sheet S355MC automobile structure steel strip is mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time.

EN10025-6 S460QL structural steel plates are European standard low alloy high strength steel materials. S355MC automobile structure steel strip, S460QL steel plates are mainly used for building and engineering structures, such as plant structure, body steel frame components of bulldozers, loaders etc. all kinds of construction machinery, bridges, ships and so on.

S355MC automobile structure steel strip, 13CrMo44 steel plate is a kind of steel which with Cr, Mo,Cr-Mo and mainly used for pressure vessels. The steel grade 13CrMo44 is according to DIN 17155 standard which with the yield strength of 242MPa. The DIN 17155 13CrMo44 steel plate chemical composition is the content of C is 0.15, Mn is 2.00, S is 0.03, Cu is 0.30, Si is 1.00, P is 0.045, Cr is 17 or 19 and the Ni is 8 or 10.

Over the years, the company has maintained long-term stable business relationships with major domestic steel mills and foreign steel companies. The company's main boiler and pressure vessel steel plates, low alloy high-strength steel plates, wear-resistant steel plates, corrosion-resistant steel plates, S355MC automobile structure steel strip bridge steel plates , strucural teel plates, steel plates for alloy structures, mold steel plates, steel plates for shipbuilding and production platforms, composite steel plates, steel plates for oil and gas pipelines. Welcome to come China and visit our S355MC automobile structure steel strip production line.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
