1inch BP300 bulletproof steel width Hot Rolled Plate

The production process of weathering steel plate is complicated, which is also the key to guarantee its good performance. Through special production and processing technology, we can better apply BP300 bulletproof steel width, weathering steel plates to various fields. Like some home landscape design, we can see the different charms of weathering steel plates. Weathering steel plates are also used in the construction field. Weathering steel plates can be used to make stairs and walls, and have good practical effects.

Composition characteristics of low alloy structural steel, BP300 bulletproof steel width: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium BP300 bulletproof steel width carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some BP300 bulletproof steel width alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
