The application of laser processing technology in processing of SPA-H cold rolled weathering steel angles

Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while SPA-H cold rolled weathering steel angles steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of SPA-H cold rolled weathering steel angles steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.

Manufacturing method of 12Cr1MoVR alloy: This plate is melted in oxygen top blown converter, open hearth furnace or electric furnace. After negotiation with the demander, other equivalent methods can also be adopted. SPA-H cold rolled weathering steel angles, 12Cr1MoVR alloy steel plate is usually delivered in normalized + tempered state. According to the special agreement at the time of ordering, 12Cr1MoVR steel plate can also be delivered in Annealed or tempered state.

Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.

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.

The company has always been adhering to the business philosophy of "integrity-based, responsibility oriented, quality first, reputation first" and is committed to building a world-class steel materials and service provider. We will continue to work hard to carry forward the enterprise tenet of "quality is the life of the enterprise, survival by quality, development by reputation", and become an enterprise with strong vitality! We always keep it in mind that profit is important to enterprises. But what counts more is social responsibility.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate SPA-H cold rolled weathering steel angles EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
