The leading SM400B grade steel supplier and exporter in China

In recent years, in line with the development trend of iron and SM400B grade steel steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which SM400B grade steel are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

Hardness is the characteristic of providing excellent wear-resistant protection during the whole service life of wear resistant steel plate. High hardness minimizes wear because the sharp edges of the abrasive are difficult to cut into a hard surface. Wear resistant steel plate can be used for bucket, loader, dump truck, powder concentrator, chute and various wear-resistant lining plates. SM400B grade steel, Wear resistant steel plate can withstand any form of wear from a variety of rocks, sand and gravel.

A516 Gr65 steel is a carbon steel plate for medium and low temperature pressure vessels, which implements the ASTM A516 standard. A516 Gr65 plate has the following characteristics: good impact resistance, small temperature deformation, good welding performance, good fatigue resistance, good anti-layered cracking performance, micro-alloying, high purity, low carbon equivalent, strong resistance to sulfur and hydrogen. Our SM400B grade steel pressure vessel plate has good dimensional tolerance and surface quality.

"Our mill has three production lines:1).2500mm production line (Width: 1600-2300mm, SM400B grade steel 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 SM400B grade steel 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 SM400B grade steel production capacity: 3.5 million tons."

20# seamless steel pipe chemical composition: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25. 20# seamless steel pipe mechanical properties: recommended heat treatment temperature: 910℃, tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%, impact energy is not required. 20# seamless steel pipe hardness is higher than 10# seamless steel pipe. SM400B grade steel, 20# seamless steel pipe has good weldability, no temper brittleness, and its machinability can be improved by water quenching. 20# seamless steel pipe can be used to make welded components, as well as parts with small load after forging, hot stamping and cutting.

Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world.
