200 series, chromic - nickel - manganese austenite stainless steel

300 series, chromic - nickel austenite stainless steel

Model 301, it is good to extend a gender, use at shaping product. Also can make its rapid and sclerotic through machining. Weldability is good. Anti-wear properties and fatigue intensity excel 304 stainless steel.

Model 302, corrosion resistance is the same as 304, because contain carbon,want relatively tall strength is consequently better.

Model 303, through adding a few sulfur, phosphor makes its relatively treatment of 304 easier cutting.

Model 304, current model; Namely 18/8 stainless steel. GB brand is 0Cr18Ni9.

Model 309, than 304 have better be able to bear or endure lukewarm sex.

Model 316, afterwards the after of 304, the 2nd gets the steel that uses the most extensively is planted, basically use at food industry and surgical operation equipment, add molybdenum element to make its obtain a kind to fight cankerous special structure. As a result of than 304 its are had better fight chloride to corrode ability to also be made consequently " marine steel " will use. SS316 is used at nuclear fuel to reclaim normally device. 18/10 class stainless steel also accords with this application level normally. [1]

Model 321, besides because added titanium element,dropped material welding line other property is similar besides rustily risk 304.

400 series, ferrite and martensite stainless steel

Model 408, hear resistance is good, weak corrosion resistance, the Cr of 11% , the Ni of 8% .

Model 409, the cheapest model (flower beauty) , use as normally car vent-pipe, belong to ferrite stainless steel (chromium steel) .

Model 410, martensite () of high strenth chromium steel, wearability is good, corrosion resistance is poorer.

Model 416, the treatment performance that added sulfur to improve data.

Model 420, " cutting tool class " martensite steel, this plants tall chromium steel of similar cloth family name the earliest stainless steel. Also use at surgical operation cutting tool, what can do is very shining.

Model 430, ferrite stainless steel, adornment is used, use at car act the role ofing to taste for example. Shape goodly quality, but be able to bear or endure Wen Xinghe corrosion resistance wants difference.

Model 440, steel of high strenth cutting tool, contain carbon tallish, after can obtain the heat treatment with proper course to succumb higher intensity, hardness can achieve 58HRC, belong to the hardest stainless steel. The commonnest application example is " razor piece " . Commonly used model has 3 kinds: 440A, 440B, 440C, still have 440F(easy treatment) additionally.

500 series, heat-resisting chromic alloy steel.

600 series, stainless steel of martensite precipitation sclerosis.

Model 630, model of the most commonly used precipitation sclerosis stainless steel, also call 17-4 normally; 17%Cr, 4%Ni.
