Brief introduction of stainless steel data

Stainless steel definition
Stainless steel is one kind can resist cankerous tall alloy steel. Have beautiful appearance, need not adopt plating look or paint substandard expresses processing, so a lot of machinery plants are indicate from is stainless steel, often do not make any paint processing, and black capable person (alleged black capable person is namely normally steely title) be to must undertake antirust processing.

The handy classification of stainless steel
Stainless steel can the cent of shallow is 200 series, 300 series and 400 series 3 kinds big, meantime 300 series are the most commonly used, 200 series and the substitute that 400 series are 300 series on sure Cheng, and will strictly tell 400 series not to make stainless steel, make do not become rusty iron, as a result of inside do not contain nickel element, use magnet to be able to be attracted so. And 200 series and 300 series have nickel, do not have magnetism so, suck iron to be not sucked.

304 it is the sort that sees at most in 300 series, change from the quote of 304 normally so can the quoted price that differentiate gives all stainless steel goes situation. 200 series contain nickel little, 400 series do not contain nickel, 300 series contain nickel most, suffer nickel price to affect so the biggest is 300 series.

300 series can brief cent is 304, 304L, 316, 316L, 321, 309S, 310S is waited a moment, the content that the basis of difference is all sorts of tantalum is not identical, the character of the stainless steel with not identical content is not identical also, the 304 difference with 304L depend on carbon (C) of content not identical, those who take L is to make clear contain carbon low, also make low carbon, the 316 difference with 316L also are identical.
The appearance of stainless steel is classified
Stainless steel can be divided to coil board, plank, profile, steel tube and component 5 kinds big, the mainest is coil and board. Profile is namely by board of make it all sorts of not identical model the data of shape, have angle iron, flat steel, I-steel, channel. Steel tube basically is to point to seamless steel tube, with seamless steel tube opposite is solder canal namely, difference depends on shaping. Component basically is to point to bend and flange and other dot.

Roll on material and plank practice identical, leave factory way is not same stopped, roll material is hank hank namely, plank is a piece a piece, if leave factory,be plank namely, also call former outfit board, it is thick normally board, as a result of very thick word, it is to cannot be become coil, normally 16 millimeter above cannot be become coiled.

Have coil, have board, a lot of moment are board, coil and board quote also is not identical, if be to buy,coil, weigh heavy business accounting by practice namely, quoted price is so high, board be business accounting of according to theory, quoted price is low, the reason is to have next difference, be like the practice with thick 10mm may be 9.6mm, this center can have price difference.
