Hot rolled GB/T 4171 Q310GNH steel sheet properties

GB/T 4171 Q310GNH steel sheet,Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.

Steel pipe refers to the steel with openings at both ends and hollow section, and its length is larger than that of surrounding steel. According to the processing technology, it can be divided into seamless steel pipe and welded steel pipe, . The production methods mainly include hot rolling, cold rolling, extrusion, cold drawing, forging, welding, etc. The size range of steel pipe is very wide, from capillary with small diameter to large diameter pipe with several meters. Steel pipe can be used for pipeline, thermal equipment, mechanical industry, petroleum geological exploration, container, chemical industry and special purpose.

As for Q460 series low alloy steel, there are three quality Grade C, D, E Q460C steel plates are mainly used in various large-scale engineering structures and light-weight structures that require high strength and large load Q460C steel mechanical properties: Q460C yield strength MPa in different thickness: ≤16mm: ≥460; 16-40mm: ≥440; 40-63mm: ≥420; 63-80mm: ≥400; 80-100mm: ≥400; 100-150mm: ≥380 The tensile strength MPa: 550-720Elongation: ≥17%Impact test: 0 ℃ impact test: ≥34J,GB/T 4171 Q310GNH steel sheet.

GB/T 4171 Q310GNH steel sheet,Pipeline steel can be divided into three types: high cold, high sulfur area and submarine laying. According to the development trend, service conditions, main failure forms and failure reasons of oil and gas pipelines, it is required that the pipeline steel not only has good mechanical properties, but also has negative temperature resistance, corrosion resistance, seawater resistance and hsscc resistance. These pipelines with bad working environment have long lines and are not easy to maintain, so they have strict quality requirements.

GB/T 4171 Q310GNH steel sheet,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.

GB/T 4171 Q310GNH steel sheet,The company is mainly engaged in steel plates manufacturing and deep processing, sales and distribution. It is committed to building a complete modern steel purchase and sale network.
