In August 2011, the expanded license for the special equipment material manufacturing of A572 Grade 60 HSLA Steel steel plates for heavy steel boilers and pressure vessels successfully passed the expert review and identification. At this point, the company has the qualification to produce steel plates for boilers and pressure vessels with a maximum thickness of 80 mm. Production continues to be at the leading domestic level. Our boiler steel plate has been widely used in the A572 Grade 60 HSLA Steel manufacture of I, II, III pressure vessels and various pressure vessel reaction tanks.In recent years, in line with the development trend of iron and A572 Grade 60 HSLA Steel steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which A572 Grade 60 HSLA Steel are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized A572 Grade 60 HSLA Steel are higher than that of annealed A572 Grade 60 HSLA Steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of A572 Grade 60 HSLA Steel is simple, the cost is low, the productivity is high, and it is widely used in actual production."The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, A572 Grade 60 HSLA Steel tube.The extrusion method is to pierce the billet or ingot with a piercer, and then extrude it into a steel tube with an extruder. This method is less efficient than the cross rolling method and is suitable for the production of high-strength alloy steel tubes."The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
