Top KF36 offshore engineering steel manufacturer in China

KF36 offshore engineering steel,Over the years, the company has established a standard of steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.

ASTM A537 steel is a heat-treated carbon silicon manganese steel plate for ASTM pressure vessels, which is divided into 3 levels A537 CL1, A537 CL2, A537 CL3. , A537 CL1 plates delivery status: normalizing; When the A537 CL1 plate thickness is ≤65mm, the yield strength is ≥345MPa, and the tensile strength is ≥485MPa. When the thickness is 65 - 100mm, the yield strength is ≥310MPa and the tensile strength is ≥450MPa.

KF36 offshore engineering steel,Our company produces ordinary carbon steel with high strength and good plasticity and toughness. Due to the effect of alloy elements, its strength is 25% - 50% higher than that of ordinary carbon steel, its elongation is 15% - 23%, and its impact toughness at room temperature is higher than 60j / cm 2. We have a KF36 offshore engineering steel production line specializing in the production of ordinary carbon steel plate, and strictly control its quality.

KF36 offshore engineering steel,The preparation of galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

KF36 offshore engineering steel,Q345 and Q345B are steel numbers. The differences are as follows:
1. Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B.
2. Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃).
3. Q345 does not indicate carbon content of steel; Q345B carbon content is 0.20%.
Q345 refers to carbon structural steel with yield point (σ s) of 345MPa. The following letters indicate the quality level, including A, B, C, D and E.

KF36 offshore engineering steel,The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
