Boiler vessel plate: it is used to manufacture various boilers and important accessories. Because the boiler steel plate is in the medium temperature (below 350 ° C) and high pressure state, in addition to bearing high pressure, it is also subject to impact, fatigue load and water and air corrosion. BV grade D refrigerated cargo ship steel. It is required to ensure a certain strength and good welding and cold bending performance. It is a special steel plate for pressure vessel, which is widely used in China.
The development BV grade D refrigerated cargo ship steel of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with BV grade D refrigerated cargo ship steel high-quality and efficient services, work together for win-win, and create a better tomorrow!
The purpose of BV grade D refrigerated cargo ship steel quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of BV grade D refrigerated cargo ship steel. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
Compared with the common pressure vessel, the pressure parts of the boiler not only bear the pressure, but also suffer from the radiation and erosion of the high temperature flue gas. Once the pressure components of the boiler fail in operation, it will cause extremely serious consequences. Therefore, the BV grade D refrigerated cargo ship steel, steel materials used to manufacture the pressure components of the boiler must have enough high strength, plasticity, toughness, fatigue resistance and corrosion resistance, as well as good high-temperature mechanical properties for high-temperature components.
Our company will accept the product quality objection registration record, pass it to the BV grade D refrigerated cargo ship steel production unit and relevant departments, and timely coordinate the supervision of product BV grade D refrigerated cargo ship steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
