Wholesale price of bp370 bulletproof quality matrial

The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep BP370 bulletproof quality processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and BP370 bulletproof quality steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

Is carbon steel 20#? Carbon steel means that alloy elements are not specially added into the steel, which is divided into ordinary carbon structural steel and high-quality carbon structural steel. The grades of ordinary carbon structural steel are Q195, Q215, Q235 and Q275. The grades of high quality carbon structural steels are: 10#, 20#, 45#, 15Mn, 20Mn, 25Mn, 30Mn, 35Mn, 40Mn, 45Mn, 65Mn, etc. It can be seen that BP370 bulletproof quality, 20# steel is carbon steel, but carbon steel means more than 20# steel.

The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. BP370 bulletproof quality, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.

The BP370 bulletproof quality steel making furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the BP370 bulletproof quality internal quality of the steel.

For Q235 steel, Q represents the yield limit of this material, and the following 235 refers to the yield value of Q235 steel, which is about 235 MPa. The BP370 bulletproof quality, Q235 steel yield strength decreases with the increase of the thickness of the material. The yield strength is 235 MPa when the plate thickness / diameter is ≤ 16mm; 225 MPa is the yield strength when the thickness is 16mm < plate thickness / diameter ≤ 40mm; 215 MPa is the yield strength when 40mm < plate thickness / diameter ≤ 60mm; 205 MPa is the yield strength when 60mm < plate thickness / diameter ≤ 100mm; 195 MPa when the plate thickness / diameter is ≤ 150mm; 195 MPa when the thickness / diameter is less than 150mm; and ≤ 200mm when the thickness / diameter is less than 150mm The yield strength is 185 MPa.
