On Jan. 31, 2019, BBN steel held the annual meeting with all employees, family members, and friends. It is a moment of joyand it is a moment to summarize the past and look forward.Looking back on 2018, BBN steel exported P235GH tensile strength more than 2 million tons of steel materials to all parts of the world and made outstanding contributions to infrastructure construction at home and abroad. In 2019, BBN steel will make p235gh tensile strength persistent efforts and forge ahead.

The company adheres to the principle of integrity, standardization and efficiency, wins the market with technology, gains reputation with creative services, and wholeheartedly provides customers with high-quality p235gh tensile strength, efficient and fast services. Facing the future, adhere to independent innovation.

Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from p235gh tensile strength. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.

In view of the characteristics of container transportation, such as high added value, low cargo damage and short time, our company takes more consideration of port collection and distribution conditions, port facilities, flight density and route coverage when choosing ports. For the convenience of customers, as well as the safety of goods.

The microstructure of the quenched and tempered alloy steel, p235gh tensile strength after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.

The alloy steel plate is among our business scope, and it is one of our main product. If you have any demands or questions about alloy steel plate, such as 34CrMo4 p235gh tensile strength material properties, 42CrMo4 AISI equivalent, 12Cr1MoV equivalent ASTM, 40Cr material specification, 42CrMo hardness, 50CrMo4 chemical composition and so on, please free free to communicate with us. We have professional technical team and sales team, who will give you p235gh tensile strength professional answers and quotation about alloy steel plate in time.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
