Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, ASTM A283 mild steel coil based on a high starting point and high technology, the company has vigorously developed various steel products ASTM A283 mild steel coil and deep-processed parts, steel structures, precision castings, seamless pipes.
The abrasion resistant ASTM A283 mild steel coil 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.
The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. ASTM A283 mild steel coil, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.
The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products ASTM A283 mild steel coil. Today, the company will further expand its scale on the existing basis, with first-class products and better service, to make new friends from all over the world, hope that we will work together to create brilliant! Serve our customers with the concept of "being honest and operating with integrity"!
20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. ASTM A283 mild steel coil, 20 # material has low strength, good toughness, plasticity and good weldability.
