"Metals and alloys corrosion atmospheric corrosion, Part 2: Guidance values for corrosion grades" is a national recommended standard, which mainly provides the corrosion grade guidance values for metals and alloys in different atmospheric environments. These guidance values help to evaluate and compare the effect of different atmospheric conditions on the corrosion of metals and alloys. The standard corresponds to the international standard ISO 9224 and provides a practical reference for engineering design and material selection, ensuring the Reliability and durability of equipment and structures in the actual use environment.
