Q355NHB steel plate is atmospheric corrosion-resistant steel plate, also known as weather-resistant steel plate. It is a low alloy steel series between general steel and stainless steel. Weather-resistant steel is made of ordinary carbon steel with a few corrosion-resistant elements such as copper and nickel. A131 grade D ship repairing steel, Q355NHB steel sheet is featured by good toughness, plastic extension, forming, welding and cutting, abrasion, high temperature, fatigue resistance, etc.
The Peru customer has cooperated with us since April 2015, and then they purchased 300 tons A36 mild steel plates as trial order. Since then, they book more than 1000 tons from us every time, and about two times every year. They asked SGS test every time. Through our cooperation those years, we have built very good relationship and they entrust us to buy other related A131 grade D ship repairing steel products for them from China also. And they have introduced us good customers in Peru, among which there are also governmental projects. It is a win-win cooperation between us.
There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products A131 grade D ship repairing steel are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.
The results of adopting two-level A131 grade D ship repairing steel service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and A131 grade D ship repairing steel after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled A131 grade D ship repairing steel plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive A131 grade D ship repairing steel industry and agriculture equipment.
