What is Q235D carbon steel material equivalent steel grade in China

In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of Q235D carbon steel material high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Anshan Iron and Steel's 4300 mm rolling mill, Shagang's 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's Q235D carbon steel material technical equipment.

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. Q235D carbon steel material, 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.

The company has a perfect after-sales service system and quality assurance system. The company adheres to the service principle of "all for users", and has established a professional after-sales service team. In the future service process, the after-sales service adopts regular return visit for customers. Timely understand the customer's satisfaction with our products, and solve the user's problems at any time.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
