09CuPCrNi-B chemical composition strength

The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)

Q355GNH weathering steel is a kind of atmospheric corrosion resistant steel, which has better corrosion resistance than 09CUPCRNI-B chemical composition, ordinary carbon steel by adding less alloy elements. Q355GNH weathering steel has been widely used in container, railway vehicle, bridge, building and air preheater which need to be resistant to atmospheric corrosion. Q355GNH weathering steel is characterized by the addition of less Cu, P, Cr, Ni and other alloy elements in the steel, so that a dense amorphous spinel type oxide layer with a thickness of about 50-100μm is formed between the rust layer and the base metal, which can prevent oxygen and water from penetrating into the steel matrix, slow down the development of corrosion to steel materials, and improve the atmospheric corrosion resistance.

In steel standard JIS G3106, SM570 steel owned the highest yield strength above 460 Mpa, and the tensile strength within 570-720 Mpa. For SM570 steel, the C element content is 0.18%, the Si element content is 0.55% max, the Mn element content is 1.60% max, the P element content is 0.035% max, the S element content is 0.035% max. 09CUPCRNI-B chemical composition, SM570 steel with thickness from 6mm-300mm,width from 1500mm-4000mm,length from 5000-16000mm.

Q345D seamless pipe has good comprehensive mechanical properties, low temperature impact toughness, cold stamping and cutting processability, weldability. In Q345D seamless pipe, Q is the abbreviation of yield strength, 345 is the yield strength value, that is, the yield strength of Q345D seamless pipe is 345 MPa, and D is the impact temperature, which is minus 20℃. 09CUPCRNI-B chemical composition, Q345D seamless pipe is widely used in various welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, storage tanks, heavy machinery and equipment, mining machinery, power stations, plant structures, low-temperature pressure vessels, textile machinery parts, etc.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.

It is a modern high-tech professional enterprise integrating scientific research, 09CUPCRNI-B chemical composition production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as 09CUPCRNI-B chemical composition process technology development, technology transfer and related technical consulting and technical services.
