Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to materials and properties. According to the different uses, it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, A514 grade P structural steel material, welding gas cylinder and pressure vessel steel, pipeline steel, etc. We adhere to the tenet of "customer first, quality assurance and good reputation", and always provides high-quality products for our customers.
With the development of China's A514 grade P 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 grade P structural steel material products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.
The hot rolling method is to heat the A514 grade P structural steel material 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 A514 grade P structural steel material rolling process is usually called semi-finished product production, also called blank production.
The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in A514 grade P structural steel material etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.
We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
