Heat treatment process and purpose of S420NL carbon steel plate sheet

Steel material has an irreplaceable role in many projects, especially in building construction, bridge cofferdams, road construction, foundation pit support, garden engineering, excavator paving, subgrade engineering and other projects. Therefore, the quality of S420NL carbon steel plate sheet steel material can not be ignored, so how should customers identify the authenticity of steel when choosing steel materials? Today we would like to analyze it together. So that it can help you to purchase satisfied steel materials in the future.

In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product S420NL carbon steel plate sheet structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel S420NL carbon steel plate sheet supplier in the world.

we also provide the S420NL carbon steel plate sheet welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful S420NL carbon steel plate sheet welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.

Will S420NL carbon steel plate sheet, stainless steel rust? Under normal conditions, stainless steel will not rust. It has a great relationship to the composition of stainless steel. In addition to iron, stainless steel has chromium, nickel, aluminum, silicon and so on elements. Scientists have found that the more uniform the internal structure of steel, the closer the various components are linked, and the more difficult it is for corrosive substances to invade. In addition, a layer of oxide protective film is attached to the surface of stainless steel, which is just like wearing armor on steel, it is not easy to rust.

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
