The difference between low alloy high strength steel plate and carbon steel plate, A514 grade B structural steel material:(1) Strength difference between low alloy high strength steel plate and carbon steel plate:The strength of low alloy high strength steel plate is higher than that of carbon steel plate;(2) Hardness difference between low alloy high strength steel plate and carbon steel plate:The hardness of low alloy high strength steel plate is higher than that of carbon steel plate;(3) Usage difference between low alloy high strength steel plate and carbon steel plate:The application range of low alloy high strength steel plate is wider than that of carbon steel plate.
Wear resistant plate is composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal conditions, the thickness of the A514 grade B structural steel material alloy wear-resistant layer of the wear-resistant plate is 1 / 3-1 / 2 of the total thickness. When working, the matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the A514 grade B structural steel material wear-resistant property to meet the requirements of specific working conditions.
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.
