How to choose hot rolled p355gh material supplier

Pageviews:

The P355GH material plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The p355gh material products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.

Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to their different materials and properties. According to the different uses, p355gh material it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, welding gas cylinder steel and pressure vessel steel, pipeline steel, etc.

Alloy seamless pipe has good sealing performance and is often used in fluid transportation pipeline, such as pipelines for oil, water, natural gas, for which the steel pipe need to be buried underground for a long time. However, the alloy seamless pipe seldom causes leakage and the loss of resources can be reduced. The p355gh material, alloy seamless pipe is smooth in surface, and has small resistance to the fluid in the pipeline, so it will not block the pipeline. It can make the fluid pass through smoothly, so as to improve the efficiency of fluid transportation and speed up the transportation speed.

Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the p355gh material steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This p355gh material method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.

ASTM A285 grade A standard specification for pressure vessel plates. p355gh material, carbon steel, low- and intermediate-tensile strength. ASTM A285 grade A plates are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both.Supplementary Technology: HIC Test I NACE MR0175 1 215 | Z25 | 235 | S57 | S57.1| S58 | S58.1 1S3 |S4 Thickness: 6MM to 300MM.Width: 1500mm to 4050mm.
