The basic knowledge integration of sa573 grade 65 [450] carbon plate steel sheet

BBN employees work hard and work hard in their work. In life, colleagues care about each other, like a family, and accompany each other at important moments in life. BBN Steel organizes employees to carry out tourism activities every year, so that families can be exposed to nature and relax physically and mentally. The good combination of working and rest can achieve the goal of hard work and happy life.

Composition characteristics of sa573 grade 65 [450] carbon plate steel sheet product: (1) Low carbon: Due to high requirements for toughness, weldability and cold formability, its carbon content does not exceed 0.20%. 2) Add manganese-based alloying elements. 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the steel.

Nickel element is mainly used to form and stabilize the austenite structure, so that the sa573 grade 65 [450] carbon plate steel sheet steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.
