Supply 1.8931 steel Boiler Plate

Q355GNH weather-resistant steel, that is, atmospheric corrosion-resistant steel, is a low alloy steel series between ordinary steel and stainless steel. 1.8931 steel, Q355GNH alloy steel plate and sheet are mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time. It is used to manufacture containers, railway vehicles, oil derricks, seaport buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.

The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the 1.8931 steel production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.

If the chromium content in 1.8931 steel alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.

Vanadium is a weak deoxidizer. Adding vanadium into 1.8931 steel steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
