ASTM A387 steel is the standard specification for pressure vessel plates, alloy steel, chromium-molybdenum. Plates under this standard Hebei Metals supplies include ASTM A387 Grades 2, NM450 sheet price Grade 12, Grade 11, Grade 22, Grade 22L, Grade 21, Grade 21L, Grade 5, Grade 9, Grade 91. Each grade except Grades 21L, 22L, and 91 is available in two classes of tensile strength levels. These Cr-Mo A387 alloy steel is primarily manufactured for welded boilers and pressure vessels for elevated temperature service.

Wear-resistant plates are very easy to understand from the literal. They are steel plates designed for large-area wear conditions. Because of its outstanding wear resistance, wear plates have their own unique uses, such as mining machinery and equipment. Ore processing, transportation of ore, ore and equipment often produce severe friction. NM450 sheet price, General steel plates cannot be subjected to friction for a long time and are easily damaged. Wear plates are very effective in solving this problem.

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of NM450 sheet price, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of NM450 sheet price, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality NM450 sheet price products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
