The significance of developing Q235NH tower steel

Alloy plate is a kind of steel plate with high thermal strength and oxidation resistance at high temperature, which has certain hydrogen corrosion resistance. Alloy plate is a new type of steel plate formed by adding other elements on the basis of steel plate material, which is to solve the problems existing in ordinary carbon steel plate. Alloy plate can be divided into bridge steel plate, boiler steel plate, shipbuilding steel plate, armored steel plate, automobile steel plate, roof steel plate, structural steel plate, silicon steel sheet, spring steel plate, Q235NH tower steel, etc.

The whole plant covers an area of 18,480 square meters, a workshop area of 9,500 square meters, and a final assembly workshop of 4,300 square meters; fixed assets are 25.50 million yuan. The company has Q235NH tower steel strong technical force, complete quality assurance system sophisticated tooling equipment and advanced technology. It can provide high efficiency professional equipment and Q235NH tower steel pressure vessels for domestic and foreign chemical, petroleum, chemical, metallurgical, pharmaceutical, fertilizer, textile, and environmental protection industries.

The company has passed ISO quality management system certification, domestic advanced production technology, and high product batch stability. Selected materials, the source controls every quality link to ensure Q235NH tower steel product high quality. Use automated, scientific and systematic manufacturing processes to meet the different needs of customers. Become an excellent domestic steel plate manufacturer, serving customers all over the world.

Composition characteristics of low alloy structural steel, Q235NH tower steel: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.
