The main characteristics of hardox 400 thickness range weldability
Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of HARDOX 400 thickness range 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 HARDOX 400 thickness range 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.
The seamless steel pipe for general use is rolled by common carbon structural steel, HARDOX 400 thickness range, low alloy structural steel or alloy structural steel, with the largest output. It is mainly used as the pipe or structural part for conveying fluid. According to different uses, it can be divided into three categories: a according to chemical composition and mechanical properties; B according to mechanical properties; C according to hydrostatic test. If the steel pipe supplied according to class AB is used to accept liquid pressure, hydrostatic test shall also be carried out. The seamless pipes for special purposes include seamless pipes for boiler, chemical power, geological and petroleum, etc.
Carbon steel is easy to be forged and processed into other products. Alloy steel and other steel products require too much investment for later processing equipment, and the processing is relatively cumbersome. In addition, the use of carbon steel has a long history, and people have rich experience to operate carbon steel, HARDOX 400 thickness range. It is more handy for the operation and processing of carbon steel. In addition, carbon steel has a wide range of adaptability, from the sea to the land. No matter high temperature or severe cold, the stability of carbon steel is always very reliable.
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 HARDOX 400 thickness range are higher than that of annealed HARDOX 400 thickness range, but the elimination of internal stress is not as good as annealing. The normalizing operation of HARDOX 400 thickness range is simple, the cost is low, the productivity is high, and it is widely used in actual production.
HARDOX 400 thickness range, S235JR VS S275JR VS S355JR plates in yield strength: For plate thickness ≤16mm, the min. yield strength of S235JR plates is 235 Mpa, S275JR plates is 275 Mpa, S355JR plates is 355 Mpa. The yield strength of S235JR S275JR S355JR plates reduces with the increasing of plate thickness. S235JR VS S275JR VS S355JR plates in tensile strength: For plate thickness 3-100mm, the tensile strength of S235JR plates is 360-510 Mpa, S275JR plates is 410-560 Mpa, S355JR plates is 470-630 Mpa. For plate thickness 100-150mm, the tensile strength of S235JR plates is 350-500 Mpa, S275JR plates is 400-540 Mpa, S355JR plates is 450-600 Mpa.
Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
