Which is better, carbon steel or Q355GNH, Q415NH, Q460NH weathering steel?

The company is a large Q355GNH, Q415NH, Q460NH weathering steel steel supplier and exporter specializing in steel coil, steel plate, steel tube and section steel. The company has always put service and quality first, offered reasonable price, taken small profits and quick turnover as the principle, honest and trustworthy as the purpose. The success of the company is not only the hard work and wisdom of all the employees of the company, but also the deep love of our customers. We will continue to achieve new leaps and create greater brilliance of the Q355GNH, Q415NH, Q460NH weathering steel enterprise, and make our own contribution to the development of the world economy.

Q690C steel plates are mainly used in heavy machinery, marine engineering, metal structures. BBN STEEL cooperated with Wugang to produce Q690C steel for use in its enterprise production and construction projects. The prospects for produts exporting to the United States, Canada, Australia, India, and Europe are promising. More than 10,000 tons Q355GNH, Q415NH, Q460NH weathering steel products have been directly supplied to European customers.

Compared with Q355GNH, Q415NH, Q460NH weathering steel, pressure vessel and boiler steel plates have such advantages: The pressure vessel and boiler steel should be pure, and the fracture structure of the boiler steel plate should be uniform without cracks and inclusions. Besides, the strain aging sensitivity is small, and the strain aging impact value of the pressure vessel and boiler steel plate is required to be no less than 50% of the non-aging impact value. That is why pressure vessel and boiler steel plate is first choice for fabricating pressure vessels and boilers, while Q355GNH, Q415NH, Q460NH weathering steel is not.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of Q355GNH, Q415NH, Q460NH weathering steel nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of Q355GNH, Q415NH, Q460NH weathering steel steel, can be used as an alloying element of low alloy steel.
