Common specifications of nm550 steel wear resistance

BBN steel company was founded in 2000, starting the international business in 2010 and successfully being approved and certified by ISO9001:2008. After ten years development, BBN steel has become the large-scale comprehensive enterprise group, combining steel trading, NM550 steel wear resistance plate processing, and steel distribution, also have large warehouse and processional representatives both inTianJin, Zhengzhou and Beijing city.

A203GrD steel plate belongs to ultra-low temperature container plate. ASTM A203 is a low-nickel alloy steel, including five grades A, B, D, E, and F. Among them, Grades D, E, and F have a nominal nickel content of 3.5%, commonly known as 3.5Ni steel. A203D/E/F steel has good impact toughness and mechanical properties in a low temperature environment, and is usually used in a low temperature environment of -70～-101℃ (the tempered state can reach -107℃).

What are the characteristics of medium and thick plate, NM550 steel wear resistance? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, NM550 steel wear resistance is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This NM550 steel wear resistance production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate NM550 steel wear resistance size.

Q355B steel and NM550 steel wear resistance steelBoth Q345B and Q355B are low alloy steels. The difference is that the yield strength of Q345B low alloy steel and Q345B low alloy steel is different. In Q345B low-alloy steel, q represents the yield strength of this material, and the latter 345 represents the yield value of this material is around 345mpa. Q in Q355B low-alloy steel also represents the yield strength of this material, and the latter 355 indicates that the yield value of this material is around 355mpa.

The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible.
