Basic knowledge about wear resistance of nm400

A709MGr36 material is an American standard carbon steel plate for bridges. The bridge plate is a thick steel plate for the manufacture of bridge structural parts. It has been widely used in construction steel structures, construction machinery and other steel structures. Production wear resistance of NM400 specifications: thickness 5mm-400mm, width 1500mm-3900mm, length 3000mm-18000mm. After agreement between the two parties, the supply of steel plates of larger specifications.

For Q345B steel plate, Q stands for the yield of Q345B material. The 345 at the back refers to the yield value of Q345B material, which is about 345MPa. The yield value will decrease with the increase of Q345B steel plate thickness. Q345B steel plate has good comprehensive performance, low temperature performance, cold stamping performance, welding performance and machinability. It wear resistance of NM400 is widely used in bridges, vehicles, ships, buildings, pressure vessels, etc.

"Mirror" refers to the surface state of wear resistance of NM400 stainless steel, which is usually 8K in the industry. The common mirror stainless steel on the market is divided into 6K, 8K and 10K, which are general polishing, 6K, 8K fine grinding and 10K super fine grinding effect. The same thickness generally has no big difference, 10K mirror is brighter; the thicker the thickness, the better the effect, and the higher the processing cost.

As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another wear resistance of NM400 magnificent projects.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel wear resistance of NM400 plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
