The company mainly supplymild P355GH material equivalent steel plate, alloy steel plate, boiler plate, corten steel plates for railway, marine, automotive, home appliances, shipbuilding, construction, machinery manufacturing and oil tank projects. While accelerating the development of the main steel industry, the company adheres to a diversified development strategy and actively develops the other industry like household products, face mask machine, precision casting producing, steel structures, and heavy plates processing service.

The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing p355gh material equivalent high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.

Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while p355gh material equivalent steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of p355gh material equivalent steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.

The effect of nitrogen (N) on the properties of p355gh material equivalent and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in p355gh material equivalent and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
