Description

technical field [0001] The invention relates to a stainless steel, in particular to a high-strength stainless steel used for storage equipment, and belongs to the technical field of metal smelting. Background technique [0002] Storage equipment refers to the technical devices and tools that can meet the needs of storage and storage of goods. Storage equipment is the main symbol of the level of storage and logistics technology. Modern storage equipment reflects the development of modern storage and logistics technology. Shelves in storage equipment are relatively commonly used equipment. Due to the storage needs of special materials, the use conditions and environment of shelves are becoming more and more harsh, and the thickness of steel plates is required to be thicker and thicker. Correspondingly, the technology of steel plates used in storage equipment The requirements are also constantly increasing. Especially when it is used to store some corrosive goods, the storage ...
