Flaw detection disqualification of BV EH32 floating vessel steel

Flaw detection disqualification of BV EH32 floating vessel steel

16Mo3 steel plate is used for pressure vessel, and it is EN10028-2 designated chromium molybdenum steel alloy that is used for increasing working temperature. 16Mo3 steel plate is used to make industrial boilers and pressure vessels for the petroleum, natural gas and chemical industries. 16Mo3 steel plate is different from other raw materials in welding: BV EH32 floating vessel steel preheating shall be carried out first, and the weld joint shall be kept for about 30 minutes after the completion of welding.

The company has sufficient inventory and complete varieties and specifications. In line with the sales principle of low price operation and quality first, let customers buy BV EH32 floating vessel steel at ease and use it comfortably! Integrity, professionalism and efficiency are our service tenets. We will wholeheartedly provide excellent BV EH32 floating vessel steel products and high-quality services for new and old customers. We also sincerely welcome new and old customers to call and write to discuss business and guide work!

BV EH32 floating vessel steel annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of BV EH32 floating vessel steel annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. BV EH32 floating vessel steel annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

The composition characteristics of low alloy high strength steel are low carbon ≤0.20%, low alloy, and total alloying elements is less than 3%. The low carbon content is to meet the process performance requirements of BV EH32 floating vessel steel, low alloy high strength steel for engineering structural parts such as plasticity, toughness, weldability and cold deformation; adding a small amount of alloying elements (mainly Mn) to achieve the purpose of improving mechanical properties. Mn not only has a significant strengthening effect on ferrite, it can also reduce the cold brittle temperature of steel, increase the amount of pearlite in the steel, and further improve the strength.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
