Q355NH equivalent material 200-400mm mild steel

ASTM A285 is an ordinary carbon steel used for fusion welding of pressure vessel equipment, such as Q355NH equivalent material boilers, storage tanks, heat exchangers, etc. The tensile strength of the three steel grades (Grade A, Grade B, and Grade C) ranges from 310-515Mpa, and ASTM A285 steel plates are usually delivered in the rolled state. According to user requirements, Q355NH equivalent material is produced by processes such as compaction, semi-compaction, edge sealing and boiling water.

The company specializes in the research and development, production and sales of Q355NH equivalent material seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has Q355NH equivalent material five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,Q355NH equivalent material rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

"Our mill has three production lines:1).2500mm production line (Width: 1600-2300mm, Q355NH equivalent material Thickness: 6-30mm, Annual capacity: 1,600,000 Tons; 2).3500mm production line (Width: 2000-3050mm, Thickness: 10-80mm, Annual capacity: 2,000,000 Tons; 3).4300mm production line (Width: 1500-4100mm, Thickness: 6-300mm, Annual capacity: 1,800,000 Tons; The weight of each ingot can reach Q355NH equivalent material 44 tons, which is at the leading level in China. In addition, we have a 1700mm hot-rolled coil production line (width range: 900-1550mm, thickness range: 1.2-25.4mm, annual Q355NH equivalent material production capacity: 3.5 million tons."

The strength level of traditional spring steel is difficult to meet the requirements of modern industrial development. As we all know, the mechanical properties of Q355NH equivalent material, spring steel depend on the heat treatment process under the premise of material quality assurance, and the heat treatment process should also be determined according to the material itself. An important way to increase the strength of spring steel is to give full play to the role of alloying elements to achieve the best alloying effect.
