The manufacturing process of application of bp370 bulletproof

In terms of service, our service is a "one-stop" way of working. We have our own application of BP370 bulletproof processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as application of BP370 bulletproof cutting, welding, drilling, galvanizing, etc., at the lowest cost.

Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to their different materials and properties. According to the different uses, application of BP370 bulletproof it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, welding gas cylinder steel and pressure vessel steel, pipeline steel, etc.

Structural steel alloy steel plates are unaffected by high temperatures due to their Molybdenum content, creating rock-like bodies. Combustible industries involve high-temperature procedures, where assemblies made from cheap steel can wither away. Alloy steel sheets application of BP370 bulletproof are robust, recyclable, and have enhanced surface quality. A balance between both Steel and chromium forms DIN 15 Mo3 Alloy Steel plates imperious to oxidation and erosion, with brittle-free hardenability from Steel and Chromium. They don't age or decay, are anti-corrosion and have excellent thermal and heat conductivity.

S355J2 steel plate application of BP370 bulletproof rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the application of BP370 bulletproof single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.

Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. application of BP370 bulletproof, Q420C steel has good mechanical properties and weldability, good cold and hot workability.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent application of BP370 bulletproof products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the application of BP370 bulletproof technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
