LR grade B multipurpose cargo vessel steel surface treatment

LR grade B multipurpose cargo vessel steel surface treatment

Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, LR grade B multipurpose cargo vessel steel and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.

LR grade B multipurpose cargo vessel steel, European standard high strength EN10025-6 S690QL steel plates are mainly used for manufacturing construction machinery, mining machinery, all kinds of engineering machinery, such as the drilling rig, the electric shovel, the electric wheel dump, the mine motor, the excavator, and the loader for all kinds of engineering construction., etc.

Mechanical properties of 45# steel high-quality carbon structural steel: Tensile strength σb (MPa): ≥600, yield strength σs (MPa): ≥355, elongation δ5 (%): ≥16, section shrinkage ψ (%): ≥40, impact energy Akv (J): ≥39. 45# steel impact toughness value αkv (J / cm2): ≥49 (5), hardness: unheated, ≤229HB; annealed steel, ≤197HB. LR grade B multipurpose cargo vessel steel, 45# steel chemical composition % (Carbon: 0.42 to 0.50, Silicon: ≤0.40, Manganese: 0.50 to 0.80, Sulfur: ≤0.045, Phosphorus: ≤0.045, Chromium: ≤0.40, Nickel: ≤0.40, Molybdenum: ≤0.10).

Q345R steel plate is a special pressure vessel steel with a yield strength of 340 Mpa. LR grade B multipurpose cargo vessel steel, Q345R pressure vessel steel has good comprehensive mechanical and technological properties. The content of phosphorus and sulfur of Q345R pressure vessel steel is slightly lower than that of Q345 (16Mn) steel, and the tensile strength and elongation requirements of Q345R pressure vessel steel are higher than those of Q345 (16Mn) steel, and the impact toughness of Q345R pressure vessel steel is also required. Q345R pressure vessel steel is the most widely used Chinese pressure vessel steel.

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 LR grade B multipurpose cargo vessel steel 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.

The company has accumulated rich experience in long-term cooperation with new and old customers, which makes our products LR grade B multipurpose cargo vessel steel more unique in the same industry, and is favored and praised by users. We always adhere to the enterprise spirit of "integrity, dedication, and people-oriented" and the business philosophy of "creating benefits for users". As a leading international steel supplier, BEBON have two warehouses which are near by Tianjin port and Shanghai port.
