In the market, the price of A514 grade B structural steel material, alloy coil plate is unstable. When purchasing alloy plate, first of all, you need to observe the market situation, and then do a price analysis. In this way, you can buy the most favorable alloy coil plate. At the same time, you can also go to the Internet to inquire about the manufacturer of alloy coil plate. It is necessary to consult the price and ask several manufacturers for comparison. For the A514 grade B structural steel material, alloy coil plate quality, you can visit the manufacturer to have a look at the material and quality. Finally, you can choose the most suitable manufacturer to put orders.
The wear-resistant layer of A514 grade B structural steel material wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy A514 grade B structural steel material carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.
Laser cutting A514 grade B structural steel material has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the A514 grade B structural steel material cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.
The requirements for toughness impact energy of A514 grade B structural steel material, S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.
The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel A514 grade B structural steel material products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
