The unqualified flaw detection for 1.8987 EN 10025-6 high strength steel

The boiler and pressure vessel steel plates are our main products. Our main conducted standards for boiler and pressure vessel steel plates are (ASME) ASTM (S)A202, (S)A203, (S)A204, (S)A285, (S)A299, (S)A302, (S)A387, (S)A515, (S)A516, (S)A517, 1.8987 EN 10025-6 high strength steel, (S)A533, (S)A537, (S)A612, (S)A662, (S)A841, EN10028-2, EN10028-3, EN10028-5, EN10028-6, JIS G3115, JIS G3103, GB713, GB3531, DIN 17155, JIS G3116, GB6653, EN10120, etc. Our typical boiler and pressure vessel steel grades are A204 grade B, A516 grade 70, A537 class 1, A537 class 2, 16Mo3, Q245R,Q345R, etc.

At the same time of doing well in 1.8987 EN 10025-6 high strength steel production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the 1.8987 EN 10025-6 high strength steel technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.

Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.

The characteristic of niobium in 1.8987 EN 10025-6 high strength steel etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.

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.
