At present, there are 26SiMnMo (Gy5), 28CrMo (Gy4), 22SiMn2TiB (616), PRO500, 32CrNi2MoTiA (A-8), 32Mn2Si2MoA (F-3), 32Mn2SiA (F-2), BP370 steel hardness and other types of Chinese defense bullet steel. bulletproof steel plate is currently a high-strength steel plate for fire-proofing various types of firearms. The main effective firearms are Type 85 sniper rifle, 95 automatic rifle, American M16 automatic rifle, Russian assault rifle AK-47, etc.

"BBN STEEL's machining process BBN STEEL's main steel plate cutting bearing housing shape, marine machinery gearbox, 45 steel carbon plate cutting zero, Q235B medium and heavy plate, BP370 steel hardness, Q345B low alloy plate, 35#, normal carbon plate, wear-resistant steel, pressure vessel steel, storage tank steel Accessories. CNC cutting all kinds of steel special-shaped parts, steel cutting parts, mechanical parts, mold materials and zero cutting pins. The steel plate guarantees the quality of steel plate cutting, and has several automatic CNC flame cutting equipment to ensure the steel plate size. "

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of BP370 steel hardness nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of BP370 steel hardness steel, can be used as an alloying element of low alloy steel.

We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
