hot rolled SM490A carbon steel material channel

Common SM490A carbon steel material, steel plate thickness specifications are as follows: Thick steel plate: thickness greater than 4, width within 10 is less than 2000mm, width above 10 is generally 2000, 2500mm, length 4-12m; Thin steel plate: thickness less than 4mm, width 500-1500mm, length 1.5-4m; Flat steel: thickness 4-60mm, width 12-200mm, length 3-9m.

How to distinguish the inferior steel plate? 1. The surface of the fake and inferior steel plate is easy to produce scab. 2. The material of fake and inferior steel plate is not uniform and there are many impurities. The surface of fake and inferior steel plate is often pitted. Pitting is an irregular and uneven defect on the surface of SM490A carbon steel material, steel plate caused by serious wear of rolling groove. Due to the pursuit of profit by the manufacturers of fake and inferior steel plates, the groove rolling often exceeds the standard.
