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.

Our SA516Gr70 pressure vessel plate has good impact resistance, small temperature deformation, good welding performance, good fatigue resistance, good anti-layered cracking performance, micro-alloying, high purity, low carbon equivalent, strong resistance to sulfur and hydrogen. The product has good dimensional tolerance and surface quality. China made commercial use ABS A32 boat building steel steel plates are now widely used in major chemical sites.

Hydrogen (H) is the most harmful element in general steel such as commercial use ABS A32 boat building steel. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
