Export BP600 bulletproof steel grade Pressure Vessel Plate

27SiMn steel plate has high strength and wear resistance, high hardenability, good machinability, moderate cold deformation plasticity and weldability. In addition, the toughness of 27SiMn steel does not decrease much during heat treatment, but it has quite high strength and wear resistance, especially when water quenching still has high toughness; but this steel is highly sensitive to white spots and has temper brittleness during heat treatment. Tendency and sensitivity to overheating.

Standing at a new historical starting point, we adapt to the requirements of supply side BP600 bulletproof steel grade structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading BP600 bulletproof steel grade steel materials supplier.

Nickel element is mainly used to form and stabilize the austenite structure, so that the BP600 bulletproof steel grade steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.

With the increase of temperature, the yield limit of BP600 bulletproof steel grade will decrease monotonically, but the tensile strength of BP600 bulletproof steel grade will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of BP600 bulletproof steel grade. Near the blue brittleness temperature, the BP600 bulletproof steel grade strength increases and the plasticity decreases. The elongation and section shrinkage of BP600 bulletproof steel grade increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

It is very important for a company to have a sound after-sales service system, which better guarantees the interests of customers and increases the reliability of the company's products in the hearts of customers. Our company has a dedicated after-sales service team and good after-sales service reputation, and has been recognized by customers over the past decades.
