The alloying elements of low alloy steel are less than 5%. The low alloy steel is added one or several alloy elements on the basis of carbon steel to improve the performance. Such as manganese, silicon, aluminum, nickel, copper, boron, phosphorus, rare earth, etc. BV FH40 marine steel material Steel with one or more of these elements will have the advantages of high strength and toughness. Due to the addition of few alloy elements, it is called low alloy high strength steel.
The company attaches great importance to systematic management, and has passed the BV FH40 marine steel material ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on BV FH40 marine steel material quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.
Three advantages of semi-endless rolling technology: 1. The limit specification of Q345B steel is expanded from 1.5 mm × 1300 mm to 1.5 mm × 1600 mm. 2. the semi-endless rolling technology can effectively reduce the fluctuations in the temperature, size, and shape control accuracy of the strip head and tail. 3. The different parts of the strip steel BV FH40 marine steel material produced by semi-endless rolling have uniform structure and mechanical properties, the yield strength fluctuation is less than 40 MPa, and the tensile strength fluctuation is less than 20 MPa.
Corrosion resistance mechanism of BV FH40 marine steel material, stainless steel: obvious Cr2O3 film is formed on the surface of stainless steel, and the minimum content of O and Cr (10.5%) is required to obtain continuous protective film to prevent corrosion. If the protective film is damaged, it can recover naturally.
As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality BV FH40 marine steel material products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
