304 stainless steel and ordinary steel what is the difference between the price of how much difference?
According to the microstructure, the stainless steel has martensite, austenite, ferrite and duplex stainless steel. Austenitic plasticity, low strength, a certain toughness, easy to process molding, without ferromagnetism.
The addition of nickel stainless steel elements, to further improve the performance, in the air, water, steam, has good chemical stability, and water solution in many kinds of acid, alkali and salt also has enough stability, even in high or low temperature environment, can still keep its corrosion resistance advantages.
Stainless steel can keep luster in the air does not rust, because chromium alloy containing a certain amount (less than 10.5%), it can form a layer of insoluble in some medium solid oxide film on steel surface.
Stainless steel is unique in that it is determined by two elements, chromium and nickel. No chromium is not stainless steel, and the amount of nickel determines the value of stainless steel.
