What asdvantages does S460nl VS S460ML have

The company attaches great importance to systematic management, and has passed the S460nl VS S460ML ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on S460nl VS S460ML quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.

ASTM A242 is a kind of high strength low alloy steel with good atmospheric corrosion resistance. Some applications show that it S460nl VS S460ML has better corrosion resistance than ASTM A36 steel plate and ASTM a572 50 steel plate. Like weathering steel, it can be used without painting, and corrosion naturally stops and becomes a protective layer.

We have 4 typical production lines S460nl VS S460ML, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.

Corrosion resistance of stainless steel mainly owes to the formation of a very thin, adhesive and translucent chromium oxide film on the surface of stainless steel. Once the film is damaged, the chromium in the stainless steel will react with oxygen in the atmosphere to restore the film quickly. At the same time, the mechanical damage can also generate a protective film quickly to prevent the S460nl VS S460ML, stainless steel from corrosion.

20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, S460nl VS S460ML. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.

Our company has its own steel plate manufacturing plant, processing plant and steel pipe plant. We can machine the steel according to the S460nl VS S460ML customer's requirements and meet the customer's requirements.
