Shallow the raw material that talks about stainless steel

What steel is what stainless steel uses?
Stainless steel is a breed of steel, steel is to point to contain carbon (C) the quantity is in 2% say below for steel, be more than 2% it is iron. Steel attends chromium in exercising a process (Cr) , nickel (Ni) , manganese (Mn) , silicon (Si) , titanium (Ti) , molybdenum (Mo) the function that waited for alloying element to improve steel makes steel was had be able to bear or endure corrupt sex (do not go up namely.
The main factor with influence rustily stainless steel has at 3 o'clock:
One of: Of alloying element content, popularly says chromic content rusted not easily in 10.5% steel. The content of chromic nickel jumps over tall anti-corrosive properties to had been jumped over, the content that wants like nickel of 304 raw material is in 8-10% , chromic content arrives at 18-20% , so stainless steel is won't rusty usually.
Secondly: Produce the exercises skill to also can affect stainless steel corrosion resistance of the company. Exercise skill good, equipment no matter the big stainless steel plant with advanced, advanced skill is the drill in alloying element accuses, the drill of cooling temperature accuses the take out of foreign matter, billet to be able to get ensuring, cncdar of fair number of numerical control small letter because this commodity quality is smooth and steady and reliable, connotation quality is good, rust not easily. Conversely a few small steelworks device are backward, skill is backward, in exercising a process, foreign matter cannot take out, producing commodity hard to avoid will be rusty.
Thirdly: External environment, climate is as dry as a chip breezy environment rusts not easily. And air humidity is big, weather of successional overcast and rainy, or the environmental area with great acid-base value is contained to become rusty with respect to Yi Sheng in air. Stainless steel of 304 raw material, if circumjacent environment is too poor,also be can rusty.
A lot of clients buy stainless steel to bazaar, itself takes a small magnet, when seeing money, suck, think sucking those who go up is good stainless steel namely. Did not take magnetism to won't rust, originally this is the understanding of a kind of fault. Stainless steel belt does not take magnetism arrange tectonic resolution, molten steel is in condense because process adjacency condenses temperature is different can form ” of martensite of ”“ of austenite of “ ferrite ”“ to wait different the stainless steel that plans construction, stainless steel of ” of martensite of ”“ of meantime “ ferrite takes magnetism. And stainless steel of “ austenite ” its are Baconian and mechanical function, skill function solderability is good, but only the stainless steel of “ ferrite ” of from corrosion resistance character belt magnetism is ambitious at stainless steel of “ austenite ” . What the Gao Han manganese that at present market is on the move contains nickel less is alleged stainless steel of 200 series, 300 series also does not take magnetism, cncdar of fair number of numerical control small letter but its function and the of 304 space that contain nickel high are very large, instead, 304 through drawing, anneal, polish, forging wait for skill processing to also be met microstrip is magnetic, because this uses stainless steel belt not to take magnetism to come,the stand or fall of differentiate stainless steel is a kind of misunderstanding, also be unscientific.
