Welcome to BBN High Strength Steels Factory
Main product: low-temperature boilerplate, pressure vessel plate, EN 10025-6 high strength steel S690Q high-strength plate, Q245R, Q345R grade, Q420C, Q690C, Q690D, Q345R steel plate, A516 Gr 70, A572 Grade 50 equivalent. The company's long-term and stable cooperation relationship with major steel mills ensures that the company provides excellent products and high-quality services to new and old customers, and strives to build a first-class marketing system in the industry.
The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep EN 10025-6 high strength steel S690Q processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and EN 10025-6 high strength steel S690Q steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.
Nickel element is mainly used to form and stabilize the austenite structure, so that the EN 10025-6 high strength steel S690Q steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.
Composition characteristics of low alloy structural steel, EN 10025-6 high strength steel S690Q: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.
We are willing to cooperate sincerely with you with high-quality EN 10025-6 high strength steel S690Q products and sincere service to expand the market and create brilliant! We will work hard to create a first-class steel company and provide you with faster and more considerate after-sales services! Moreover, our shipbuilding steel plates have been certified by the nine countries' classification societies including DNV, ABC, GL, LR, BV, CCS, RINA, NK, and KR. The quality assurance system has passed ISO9001-2000 standard certification.
