At the same time, the company operates a variety of products of related iron and normalized CCS grade E bulk vessels steel steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained normalized CCS grade E bulk vessels steel ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.
The strength of normalized CCS grade E bulk vessels steel, 20 # steel plate is slightly higher than that of 15# steel, rarely quenched, and has no temper brittleness. Cold deformation plasticity is high, generally for bending, calendering, flange and hammer arch processing. Arc welding and contact welding have good welding performance and small thickness during gas welding. Cracks are likely to occur on parts with strict shape requirements or complex shapes.
The boiler steel plate has small strain aging sensitivity, especially in the corresponding working temperature range, a certain value of aging impact energy must be guaranteed;The boiler steel plate has low notch sensitivity, which can prevent steel from cracking in welding, opening, and local stress concentration areas;The normalized CCS grade E bulk vessels steel, boiler steel plate has good welding performance;The normalized CCS grade E bulk vessels steel, boiler steel plate has a good microstructure, white spots and cracks are not allowed.
After adding trace elements such as phosphorus, copper, chromium, and nickel to Q355NH steel, a dense and highly adherent protective film is formed on the surface of the weathering steel, which prevents rust from spreading and developing, and protects the substrate under the rust layer to slow its corrosion . An amorphous spinel oxide layer of about 50 μm to 100 μm thick formed between the rust layer and the substrate is dense and has good adhesion to the base metal, which greatly improves the atmospheric corrosion resistance of the steel material, normalized CCS grade E bulk vessels steel.
"ASTM A516 Grade 70 plate is a boiler / pressure vessel quality of steel plate for use in low to moderate services. It has improved notch toughness. normalized CCS grade E bulk vessels steel, A516 Grade 70 steel plates can be produced with thick up to 200mm.For boiler steel plate A516 Grade 70, the yield strength shall be above 260 Mpa, tensile strength from 485 Mpa to 620 Mpa.A516 Garde70 steel plate is equivalent to the P355GH and 490B grades. "
The company specializes in hot rolled plates producing, steel plate processing, steel plates cutting, carbon steel plate weldding and exporting of wide and thick steel plates. BBN company has high-quality CNC normalized CCS grade E bulk vessels steel steel plate cutting processing equipment, professional technical personnel, and supporting marketing and after-sales service system.
