weather resistant Q235NH steel hot rolled boiler steel plate

Our company was founded in 2000, which initially committed to providing high-quality steel weather resistant Q235NH steel products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export weather resistant Q235NH steel steel to the international market, opening up the international steel market.

ASTM a588 steel beam weather resistant Q235NH steel not only has high tensile and yield strength, but also has good atmospheric corrosion resistance due to its small copper content. Due to its high strength, its weather resistant Q235NH steel weight is less than that of A36 steel section without reducing strength. At the same time, it is the best material for outdoor application, the surface is orange.

Q245R boiler steel plate introduction: Q is the first letter of "Qu" Chinese Pinyin; Number 245 is the yield strength value; R: is the first character of "Rong" Chinese Pinyin. Q245R steel is a special plate for pressure vessels and boilers with a yield strength of 245MPa. It has outstanding mechanical properties and processability. If you have special requirements, our company can supply Z15, Z25, Z35 and other Z performance tests.

The hot rolling method is to heat the weather resistant Q235NH steel steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of weather resistant Q235NH steel rolling process is usually called semi-finished product production, also called blank production.

ASTM a588 is a high strength low alloy HSLA steel (high strength, low alloy) containing a small amount of alloying elements copper, chromium and AMP. Nickel. These alloying elements effectively improve the properties of a588 and expand its application range. Firstly, the alloy composition increases the weather resistant Q235NH steel yield point strength to 50 Ksi and the tensile strength to 70 Ksi. Secondly, a588 weather resistant Q235NH steel has high copper content, atmospheric corrosion resistance and long working time. Because of its excellent comprehensive performance, a588 angle steel is widely used in bridge, building and other structural fields.

From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
