Stainless hlau yog txwv kom muab zais rau hauv austenitic stainless steel, ferritic stainless steel, ob lub tsev steel hlau, martensitic stainless steel thiab nag lossis daus hardening stainless steel raws li nws cov qauv.
Ua ntej, austenitic stainless steel
Austenitic stainless steel yog lub tseem ceeb tshaj plaws hom stainless steel, thiab nws cov zis thiab ntau npaum account rau 70% ntawm tag nrho cov stainless hlau. Raws li cov alloying txoj kev, austenitic stainless steel yuav tau muab faib ua ob pawg: chrome-npib tsib xee hlau thiab hlau-chromium-manganese hlau. Cov yav tas los siv npib tsib xee raws li lub austenitizing caij thiab yog ib lub cev lub ntsiab ntawm austenitic steel; lub tom kawg xyoo kim npib tsib xee-npib tsib xee steel nrog manganese thiab nitrogen.
Feem ntau hais lus, austenitic steel muaj zoo xeb kuj, zoo kev txhua yam khoom thiab txheej txheem zog, tab sis tsis tshua muaj zog thiab hardness.
Ob, ferritic stainless steel
Ferritic stainless steel muaj 11% -30% chromium, uas yog cia li dawb ntawm npib tsib xee. Nws yog ib tug npib tsib xee-npib tsib xee hlau. Nyob rau hauv lub xeev ntawm kev siv, tus qauv no mas ferrite.
Ferritic stainless steel muaj ntau dua lub zog, qis txias ua hauj lwm hardening nyiam, zoo kuj mus Chloride kev nyuaj siab xeb, pitting xeb, crevice corrosion thiab lwm yam hauv zej zos xeb ua tau zoo, tab sis yog rhiab rau intergranular corrosion thiab cov neeg pluag nyob rau hauv uas tsis muaj kub toughness.
Peb, ob lub tsev stainless steel
Nws yog xam hais tias austenite + ferritic ob lub tsev stainless steel yuav raug xa mus rau raws li muaj ntau tshaj li 15% ntawm cov ferrite rau lub austenite matrix los yog 15% los yog ntau tshaj ntawm austenite rau lub ferrite matrix.
Duplex stainless steel combines qhov zoo ntawm austenitic hlau thiab ferritic hlau.
Plaub, martensitic stainless steel
Martensitic stainless steel yog ib hom ntawm steel uas yuav tom los ntawm tshav kub kev kho mob kom muaj siab muaj zog thiab hardness.
Tsib, nag lossis daus hardening stainless steel
Cov nag lossis daus hardening hom stainless steel yog ib tug steel uas precipitates carbides nyob rau hauv steel los ntawm tshav kub kev kho mob txhais tau hais tias ua tau lub dag lub zog txoj kev txhim kho.
