What is the difference between 1018 and Q550NH grade steel?

The company is a leading steel production and exporting group in steel materials with advanced production technology, metal-cutting skill, and steel structures engineering projects. We can supply carbon steel plate and sheet, alloy steel plates and structural Q550NH grade steel plates. These hot rolled steel plates are sturdy plates having high quality. Their imperviousness to effect and scrapped area, weld capacity, and workability make them a worthy product in a variety of industries.

The factory is located in the central China, with convenient transportation and abundant resources. The main products are various construction steel plates, steel pipes, steel sections, and steel structure processing parts. Used in the Q550NH grade manufacture of railway tracks, pressure vessels, boilers, hulls, bridges, various types of steel, etc. With an annual output of 2.23 million tons of steel plates, 2.04 million tons of steel pipes and 1.54 million tons of section steel in 2002, it is an important pig iron base in Henan Province.

Q345B material is a low carbon alloy steel grade with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345 serues steel is widely used in bridges, vehicles, ships, buildings, pressure vessels. Q represents the yield of this material, and the number 345 refers to the yield value of this material, which is around 345MPa. As the thickness of the material increases, its yield value decreases.

Modern steel-making steel purification facilities and advanced quality control methods have been perfected. Rolling steel can be produced according to controlled rolling and controlled cooling, normalizing, and quenching and tempering processes to produce σs 390-685Mpa series products. Q550NH grade, Low alloy high strength structural steel plate has stable quality, good wear resistance and low temperature toughness. It can be widely used in the manufacture of mining machinery, engineering machinery, high-rise buildings and heavy vehicles.

Q550NH grade, SS400 steel is one of the most commonly used hot rolled general structural steel. SS400 steel’s mechanical properties is yield strength more than 225-235MPa, tensile strength 360-510Mpa and 340-470Mpa. For SS400 steel, the C element content is 0.2% max, the Mn element content is 1.40% max, the P element content is 0.045% max, the S element content is 0.045% max.

SG255 gas cylinder Q550NH grade steel is widely used in petroleum, chemical industry, power station, boiler, etc, used to make the reactor, heat exchanger, separator. The company is a professional gas cylinder steel exporter and a steel stockist in china. We keep more than 1000 tons SG255 gas cylinder steel coils in Q550NH grade stock every month. If you want to get the steel price, please do not hesitate to contact us. Any need in SG255 Chemical Composition and Mechanical Properties, please feel free to contact us by email or calling to us.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent Q550NH grade products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the Q550NH grade technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
