Stainless steel vibrant wire rod is divided into: Martensitic steels, ferritic steels, austenitic steels, austenitic-tiesu (duplex) stainless steel and precipitation-hardening stainless steel. Also, the elements are divided into: chromium stainless steel, Stainless steel bright wire rod and crmnn stainless steel. Main characteristics Weldability Application needs for welding functionality also varies. Welding overall performance frequently don't require a class of tableware, even like some Pan enterprises. But most items call for raw components weldability good, cutlery, flask, like two steel pipes, water heaters, drinking fountains, and so forth. Stainless steel wire sculpture Corrosion resistance Most stainless steel goods needs resistance corrosion functionality very good, like one particular or two class tableware, and kitchen, and water heater, and water machine,, some abroad businessman on merchandise also do resistance corrosion efficiency test: with NACL water solution heating to boiling, a time Hou pour off remedy, wash NET drying, mentioned weight loss, to determines by corrosion degree (Note: goods polishing Shi, as a result of Emery cloth or sandpaper in the contains Fe of components, will led to test Shi surface appeared rust) Heat resistance Is below the higher temperature heat resistance stainless steel to keep its exceptional physical-mechanical properties. Effect of carbon: carbon formed in austenitic stainless steel is powerful and steady. Austenitic and expanded austenite element. Carbon nickel austenite is approximately 30 instances, carbon is an element of space, through strong remedy strengthening could considerably boost the strength of austenitic stainless steel. Carbon can also boost austenitic stainless steel in high concentration chloride (if 42%MgCl2 boiling aqueous answer) within the resistance to stress corrosion performance. 
Nevertheless, in austenitic stainless steels, carbon, typically known as dangerous elements, that is mostly due to the corrosion resistance of stainless steels beneath some of the situations of use, carbon and higher chromium steels of chromium in chromium-carbon compounds which can bring about partial depletion of the steel's corrosion resistance especially resistant to intergranular corrosion performance. So. 60 development of new chromium-nickel austenitic stainless steels are carbon content material is much less than 0.03% or 0.02% of ultra low-carbon, we can see that with reduced carbon content material, steel intergranular corrosion susceptibility decreased when the carbon content is decrease than 0.02% is definitely the most clear effect, some Pearl also noted that carbon and chromium also increases tendency of pitting corrosion of austenitic stainless steel. Due to the harmful effects of carbon, not merely within the refining of austenitic stainless steel and ought to be controlled as essential in low carbon content material as you can, and within the subsequent heat, is also in the course of action of cold functioning and heat treatment on stopping carbon stainless steel and carbide precipitation of chromium-free. Corrosion resistance When the atomic number of chromium content material in steel of not much less than 12.5%, the electrode potential of the steel could be mutated, rose from damaging to the optimistic electrode. To stop electrochemical corrosion.
