SA516GR70N steel is a standardized medium and low temperature pressure vessel. The overall performance is improved and the BV grade A ferry steel plate product price is higher. The steel plate has the following characteristics: good impact resistance, low temperature deformation, good welding performance, good fatigue resistance, good anti-laminar cracking performance, low carbon equivalent, and strong resistance to sulfur and hydrogen. The products available for steel plates with a thickness of less than 200mm.
In today's BV grade A ferry steel plate steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of BV grade A ferry steel plate market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.
Laser cutting BV grade A ferry steel plate 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 BV grade A ferry steel plate 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.
Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of BV grade A ferry steel plate etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in BV grade A ferry steel plate etc. steel is strictly controlled.
