The patent application with application number 200410047238.6 proposes to add 1.5-2.9% copper to nickel-saving austenitic stainless steel to achieve antibacterial effect, but due to the limited antibacterial ability of copper ions alone (about 1% of silver ions of the same weight), Therefore, the amount of copper added is relatively high, and the copper content of 2-5% will deteriorate the thermoplasticity of the steel, resulting in a decrease in performance, and after the copper is added, it must undergo high-temperature aging treatment to play an antibacterial effect, resulting in an increase in production costs; the application number is The 200510013238.9 patent application meets the antibacterial requirements by adding copper and a small amount of silver to nickel-saving and chromium-saving austenitic stainless steel, but due to the low content of nickel and chromium, the corrosion resistance of stainless steel is weak, and the scope of use of stainless steel is limited

Description

technical field [0001] The invention relates to the technical field of stainless steel materials and their preparation, in particular to a corrosion-resistant stainless steel coffee pot 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 (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.
