S550Q steel carbon mild steel plate

This standard ASME SA516 is mainly used to improve the notch toughness important for welding steel plates for pressure vessels. The tensile strength of SA516Gr.60 (HIC) is 415MPa min. The main element content is C Mn Si, P and S control determines its performance. SA516Gr.60 (HIC) chemical composition: C: ≤0.30, Mn: 0.79-1.30, P: ≤0.035, S: ≤0.035, Si: 0.13-0.45. It is a carbon steel material for medium and low temperature pressure vessels.

Over the years, the company has trained a number of professional sales talents, enriched the concept of various marketing and customer service, and strengthened the business strength of the company. Now the company's business S550Q steel department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and S550Q steel after-sales service department constitute the service customer network.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium S550Q steel carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some S550Q steel alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.

After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the S550Q steel, alloy wear-resistant steel plate is significantly improved.

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.
