A709 grade 50 carbon steel plate sheet, A 36, which one is better for construction?

The abrasion resistant A709 grade 50 carbon steel plate sheet steel plates, which also known as wear resistant steel plates, are among our main business scope. There are various abrasion resistant steel grades on the market. Among them, NM400, NM450, NM500, HARDOX400, HARDOX500, AR400, AR500, etc. are most popular. Meanwhile, NM400, HARDOX400 and AR400 are equivalent to each other. NM500, HARDOX500 and AR500 are also equivalent abrasion resistant steel materials.

NM400 wear resistant steel plate has a very high mechanical strength; its mechanical properties are 3 to 5 times that of ordinary low alloy steel plates; it can improve the wear resistance of mechanical related parts; therefore improve the service life of machinery; reduce production costs. The surface hardness of the product A709 grade 50 carbon steel plate sheet is usually Reached 360 - 450HB. NM400 wear resistant steel plate is used for processing and manufacturing of wear-resistant and wearing parts for mining and various construction machinery.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than A709 grade 50 carbon steel plate sheet. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel A709 grade 50 carbon steel plate sheet is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.

Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products A709 grade 50 carbon steel plate sheet are sold in more than 20 provinces, cities and all over the world. The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products.
