What are the factors influencing the lamellar tearing of Z-direction NV A fishing vessel steel

Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of NV A fishing vessel steel circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and NV A fishing vessel steel management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

Our company has 80 tons NV A fishing vessel steel, 7mm thickness VL Grade A hot rolled sheets in Tianjin stock. Below is the ship steel VL A plates available specification(mm): 7*2850*9850, 7*1770*6000, 7*1770*6000, 7*1950*10600, 7*2300*6000, 7*3000*12000, 7*3030*6900, 7*3180*8600, 7*2950*7350, 7*1950*10500, 7*2350*7700, 7*3030*7900, 7*3100*9300, 7*2920*9900, 7*2850*11400, 7*2400*11000, 7*3030*8000, 7*3080*7650, 7*1910*6000, 7*2950*9400.

Different form NV A fishing vessel steel, boiler steel plate is one of the most critical materials in boiler manufacturing. Boiler steel plate mainly refers to the hot-rolled special carbon steel and low alloy heat-resistant steel plate used to manufacture important components such as the shell, drum, header end cover, support and hanger in the boiler. Boiler steel plates are often working under medium, high temperature and high pressure. In addition to withstand higher temperatures and pressures, boiler steel plates are also subject to impact, fatigue loads, and water and gas corrosion, resulting in poor working conditions.

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 NV A fishing vessel steel 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 NV A fishing vessel steel etc. steel is strictly controlled.
