Product use of different requirements for welding performance are also different.
A kind of tableware does not do the requirement to the welding performance, even including part of the pot enterprises.
But most products require good welding properties.
Like second class tableware, thermos cup, steel pipe, water heater, water dispenser and so on.
(2) corrosion resistance
The vast majority of stainless steel product requirements corrosion resistant performance is good, like a, 2 kinds of tableware, kitchen utensils and appliances, water heaters, water dispensers, etc., some foreign businessmen also do corrosion resistance test of the products: with NACL aqueous solution heat to a boil, after a period of time out solution, wash and drying, weight loss, to determine the degree of corrosion (note: the product polishing, because of the sand cloth or sandpaper contained Fe ingredients can lead to test surface rust spots).
(3) polishing performance
Stainless steel products in today’s society in the production generally have to go through polishing this process, only a few products such as water heater, water dispenser inner tank do not need polishing.
So this requires the raw material polishing performance is very good.
(4) heat resistance
Heat resistance refers to the high temperature stainless steel can still maintain its good physical and mechanical properties.
(5) corrosion resistance
When the number of chromium atoms in the steel is no less than 12.5%, the electrode potential of the steel can be changed from negative to positive.
Prevent electrochemical corrosion.
