BP300 bulletproof steel length strength has much to do with its dimensions

The BP300 bulletproof steel length plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The BP300 bulletproof steel length products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.

High toughness and low brittleness transition temperature: with the increase of the working pressure of the BP300 bulletproof steel length gas pipeline, the pipe diameter becomes larger, and the pipeline fracture accidents often occur. Toughness is the key factor affecting pipeline fracture. In order to ensure BP300 bulletproof steel length pipeline safety, toughness and strength must be improved at the same time.

The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. BP300 bulletproof steel length, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.

Last year, the technicians in the automation department of BBN STEEL closely combined the needs of the production line, based on the big data platform. It has successively developed more than 10 industrial software such as intelligent boiler combustion system, equipment full life cycle system, and integration of environmental protection management and control, which provide efficient and intelligent support for comprehensive support of high-end production line production and lays a solid foundation for high-quality development.

S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. BP300 bulletproof steel length, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.

The company's after-sales service tenet is "customer first, timely guarantee, enthusiastic service and effective work". In order to establish a set of perfect after-sales service system and strict management system, so that the after-sales service can be effectively guaranteed. The company has set up after-sales service department to ensure timely, unique and effective response to every user's request, coordinate internal resources internally, and put an end to all evasion and delay.
