BBN steel company was founded in 2000, starting the international business in 2010 and successfully being approved and certified by ISO9001:2008. After ten years development, BBN steel has become the large-scale comprehensive enterprise group, combining steel trading, P355GH boiler material grade plate processing, and steel distribution, also have large warehouse and processional representatives both inTianJin, Zhengzhou and Beijing city.

The quality of p355gh boiler material grade shall not only meet the requirements of the standard, but also be higher or stricter than the product characteristics specified in the standard, including chemical composition, structure, physical properties, chemical properties and other requirements of p355gh boiler material grade buyer, such as packaging, delivery time, etc.. On the basis of the quality of p355gh boiler material grade in line with the corresponding standards, some buyers will put forward specific requirements according to their own use requirements, which is called technical agreement. That is, some specific factors should be met according to the buyer's requirements. These requirements may be the control of chemical element content of p355gh boiler material grade and certain performance limit of p355gh boiler material grade, etc.

37SiMn2MoV steel is high-grade quenched and tempered steel. p355gh boiler material grade, 37SiMn2MoV steel has excellent comprehensive mechanical properties, good heat treatment process, good hardenability, low sensitivity to quenching crack, high resistance to tempering, very low temper brittleness, good high temperature strength and low temperature toughness. Chemical composition of 37SiMn2MoV steel: C: 0.33-0.39, Si: 0.60-0.90, Mn: 1.60-1.90, Mo 0.40-0.50, V: 0.05-0.12. After quenching and tempering, 37SiMn2MoV steel is usually used to manufacture heavy load and large section important parts.

Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the p355gh boiler material grade steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the p355gh boiler material grade weathering steel is purified and the content of inclusions is greatly reduced.

15Mo3 steel plate is used for boiler and high temperature pressure vessel.15Mo3 steel plate executive standard: DIN17155Delivery status of p355gh boiler material grade, 15Mo3 steel plate: normalizingNormalizing temperature of 15Mo3 steel plate: 650 ~ 700 ℃Normalizing time of 15Mo3 steel plate: 1.5t-2.5t15Mo3 welding repair: welding repair can only be carried out after the approval of the purchaser.Requirements for tensile properties of 15Mo3 steel plate: tensile strength 450-600 MPa, yield strength 270 MPa.
