The development A572 Gr 50 high strength steel of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with A572 Gr 50 high strength steel high-quality and efficient services, work together for win-win, and create a better tomorrow!
As an experienced world class steel materials supplier and exporter, logistics and fast delivery is a crucial step to us. Our logistics department and shipping department take the responsiblity to allocate and transport steel materials from our mill and warehouse to customer port or designated destination. The cooperation of the two departemts are excellent and that powerfully support our fast delivery, and strive for shorter time for customers to receive steel materials.
Q355GNH weathering steel: Q——The first letter of the Chinese pinyin of "Qu" in the yield strength; 355——The lower limit of the lower yield strength of steel, in N/mm²; GNH——respectively the first letter of "Gao, Nai, Hou" Chinese Pinyin; Quality grades are divided into A, B, C, D, E (1)Q355GNH executive standard: GB/T 4171-2008 (2)Q355GNH smelting method: the steel is smelted by converter or electric furnace, and it is killed steel.
The boiler steel is not only required to have good corrosion resistance at low temperature, but also required to have good oxidation resistance at high temperature for components working at high temperature. Especially for the components of superheater and reheater, when they A572 Gr 50 high strength steel work at high temperature, they are required not easy to be oxidized and peeled. Generally, the development speed of oxidation depth at working temperature is required to be less than 0.1mm/year. The addition of chromium, nickel, aluminum and silicon can improve the oxidation resistance of steel.
A572 Gr 50 high strength steel, HP265 steel with the thickness range is 1.2-12mm. HP265 steel’s mechanical properties is include the yield strength more than 265MPa, tensile strength is 410-520MPa. The chemical composition of HP265 steel is C element content is 0.18, the Si element content is 0.10, the Mn element content is 0.80, the P element content is 0.025% max, the S element content is 0.015% max.
