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.

JIS g3101:2004 ss540 structural steel angle contains 0.30% carbon and 1.60% manganese, which greatly improves the strength of steel. Compared with 05CUPCRNI chemical composition SS400 and ss490, ss540 has higher strength with yield strength of 400MPa and tensile strength of 540Mpa. High strength makes it popular in applications that require strength but weight is a problem.

Carbon steel is easy to be forged and processed into other products. Alloy steel and other steel products require too much investment for later processing equipment, and the processing is relatively cumbersome. In addition, the use of carbon steel has a long history, and people have rich experience to operate carbon steel, 05CUPCRNI chemical composition. It is more handy for the operation and processing of carbon steel. In addition, carbon steel has a wide range of adaptability, from the sea to the land. No matter high temperature or severe cold, the stability of carbon steel is always very reliable.
