Quality optimization measures of SM490A carbon steel plate sheet

HP295 is mainly used in the manufacture of liquefied gas cylinders, its SM490A carbon steel plate sheet chemical composition is stable, P, S content is low, pure steel, the internal organization, fine grain. Moderate strength, good plasticity, low yield ratio, yield platform is not obvious, vertical and horizontal performance of small differences, excellent cold stamping performance.

The whole plant covers an area of 18,480 square meters, a workshop area of 9,500 square meters, and a final assembly workshop of 4,300 square meters; fixed assets are 25.50 million yuan. The company has SM490A carbon steel plate sheet strong technical force, complete quality assurance system sophisticated tooling equipment and advanced technology. It can provide high efficiency professional equipment and SM490A carbon steel plate sheet pressure vessels for domestic and foreign chemical, petroleum, chemical, metallurgical, pharmaceutical, fertilizer, textile, and environmental protection industries.

The preparation of SM490A carbon steel plate sheet 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 SM490A carbon steel plate sheet centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

When the stainless steel plate is alloyed with chromium, the type of surface oxide is changed to that formed on pure chromium metal. This tightly adherent chromium rich oxide protects the surface from further oxidation. This kind of oxide layer is very thin, through which we can see the natural luster of the steel surface, so that SM490A carbon steel plate sheet, stainless steel has a unique surface.

With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel SM490A carbon steel plate sheet product quality. Reaching every corner of the globe with professional services, users anywhere can get thoughtful and detailed services form us is our pursue. We promise all our steel materials are manufactured and tested in accordance with responding standards. We will take full responsibility for the quality of the steel materials we provide.
