Thermal processing of material sb450 equivalent steel sheet

09MnNiDR steel is pure, has good plasticity and weldability, and excellent low-temperature impact toughness. material sb450 equivalent, 09MnNiDR is used to manufacture low-temperature pressure vessel storage tanks, with a minimum operating temperature of -70℃.Executive standard: GB3531-2008Product specifications: 10 - 80 X 1500 - 4050 X L.

The main function of boron in material sb450 equivalent and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.

Strip steel is coiled and curved steel plate, which is different from common steel pipes and steel plates. Strip steel has obvious characteristics. First, it is thin and easy to curl, which is convenient for logistics and transportation. Second, the surface quality of material sb450 equivalent, strip steel is good, the luster is bright and it has good flexibility. Third, the strip steel is easy to process. When you need to use it, you only need to straighten the bent part and you can directly process it. Fourth, the precision is high, and the strip steel can be made of plain carbon steel, carbon structure steel, spring steel, tool steel, stainless steel, etc.
