Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, A514 grade H alloy steel plate based on a high starting point and high technology, the company has vigorously developed various steel products A514 grade H alloy steel plate and deep-processed parts, steel structures, precision castings, seamless pipes.
SA516Gr45 (R-HIC) This type of steel plate is mainly used in the manufacture of equipment used in wet hydrogen sulfide environment, such as: liquefied petroleum gas desulfurization system, stable absorption system for catalytic cracking, condensation system of atmospheric and vacuum distillation tower, etc. The material A514 grade H alloy steel plate has the characteristics of high purity, low P, low S, good uniformity of structure and mechanical properties, resistance to hydrogen cracking and sulfide stress corrosion.
Shipbuilding steel plates have always been the key products of our company, and it is sold well in many countries and regions around the world. The thinnest certifiable thickness of our shipbuilding steel plates is up to 3mm. We cooperate with classification societies to certify the shipbuilding steel A514 grade H alloy steel plate and issue EN10204 3.2 material test certificate. According to the certificate number, the customer can verify the source of the shipbuilding steel plates with the corresponding classification society near them.
Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for A514 grade H alloy steel plate and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
A514 grade H alloy steel plate, No.45 seamless pipe belongs to high quality carbon structural steel. The carbon (C) content of No.45 seamless pipe is 0.42 ~ 0.50%, Si content is 0.17 ~ 0.37%, Mn content is 0.50 ~ 0.80%, Cr content is ≤ 0.25%, Ni content is ≤ 0.30%, Cu content is ≤ 0.25%. The tensile strength, yield strength, elongation, reduction of area and impact energy of No.45 seamless pipe are 600 MPa, 355 MPa, 16% and 40% respectively. No.45 seamless pipe is used to manufacture high strength moving parts.
The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality A514 grade H alloy steel plate products and excellent services. Our company's products A514 grade H alloy steel plate are widely used in petroleum, chemical, power station, boiler and other industries, mainly used in reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear energy reactor pressure shells and other equipment.
We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
