A514 Gr B structural steel material, Medium and heavy steel plate is a kind of steel plate with outstanding characteristics. First of all, there are many kinds of thickness of medium and heavy steel plate, which are generally relatively thick. Secondly, the thickness of medium and heavy steel plate is relatively thick, so it can be used for high strength application such as bridges. Thirdly, the corrosion resistance and wear resistance of medium and heavy steel plate are much better than ordinary steel plate.
With the development of China's A514 Gr B structural steel material market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of A514 Gr B structural steel material products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.
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 A514 Gr B structural steel material 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 A514 Gr B structural steel material steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
Phosphorus is a very harmful element in A514 Gr B structural steel material steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of A514 Gr B structural steel material steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
Our company will accept the product quality objection registration record, pass it to the A514 Gr B structural steel material production unit and relevant departments, and timely coordinate the supervision of product A514 Gr B structural steel material quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
