What is 20MnB5 carbon equivalent steel chrome

Our company has sales department, technology department, quality inspection department, after-sales department, logistics department. Each department has professional knowledge and high professional quality, put customers first, think about the interests of customers, actively communicate with customers and solve problems smoothly.

Cold rolled coil products 20MnB5 carbon equivalent steel have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products 20MnB5 carbon equivalent steel is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils 20MnB5 carbon equivalent steel with different surface roughness can be produced (glossy surface or matte surface, etc.).
