Description

technical field [0001] The invention relates to the technical field of stainless steel cup materials, in particular to a wear-resistant and corrosion-resistant stainless steel cup material and a preparation method thereof. Background technique [0002] With the rapid development of the metallurgical industry and the improvement of daily life standards, the use of stainless steel has greatly increased, and a large number of beautiful and durable stainless steel products have entered the field of civilian consumption. Among them, the use of stainless steel in utensils and kitchen supplies accounts for the vast majority. most. Stainless steel refers to steel resistant to weak corrosive media such as air, steam, water, and chemically corrosive media such as acid, alkali, and salt. It is also called stainless acid-resistant steel. In practical applications, the steel resistant to weak corrosion medium is often called stainless steel, and the steel resistant to chemical medium co...
