nm400 material specification thickness tolerance steel plate

BBN employees work hard and work hard in their work. In life, colleagues care about each other, like a family, and accompany each other at important moments in life. BBN Steel organizes employees to carry out tourism activities every year, so that families can be exposed to nature and relax physically and mentally. The good combination of working and rest can achieve the goal of hard work and happy life.

Cold rolled steel sheet has high strength, high hardness and high surface finish. It is generally thin steel plate and can be used as stamping steel plate. The strength of NM400 material specification, hot rolled steel plate is relatively low, the surface quality can not match with that of cold rolled steel sheet. But its plasticity is good, and it is generally medium thick steel plate. The price difference between cold rolled steel sheet and hot rolled steel plate has a certain relationship with manufacturers. The quality of steel plate manufactured by different manufacturers is different, and the price is also biased.

The hardness of NM400 material specification, wear-resistant steel plate is an important standard to measure wear resistance. The hardness of wear-resistant steel plate can be divided into microhardness and surface hardness. The microhardness of carbide in the wear-resistant layer of wear-resistant steel plate can reach over HVl700-2000, and the surface hardness can reach HRC58-62. Chromium alloy is the main wear-resistant layer of wear-resistant steel plate, and other alloy components such as manganese, molybdenum, niobium, nickel are added at the same time.

The hot rolling method is to heat the NM400 material specification steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of NM400 material specification rolling process is usually called semi-finished product production, also called blank production.
