7. 317 stainless hlau. Lub pitting corrosion kuj thiab creep kuj yog zoo dua 316L stainless hlau, uas yog siv nyob rau hauv lub tsim ntawm petrochemical thiab organic acid corrosion resistant khoom.

8.321 stainless hlau. Titanium-stabilized austenitic stainless hlau, ntxiv titanium los txhim kho intergranular corrosion kuj, thiab muaj zoo kub-kub txhua yam khoom, tuaj yeem hloov tau los ntawm ultra-low carbon austenitic stainless hlau. Tsuas yog rau lub sijhawm tshwj xeeb xws li kub siab lossis hydrogen corrosion kuj, feem ntau tsis pom zoo siv.

9.347 stainless hlau. Niobium-stabilized austenitic stainless hlau, ntxiv niobium los txhim kho intergranular corrosion kuj, corrosion kuj nyob rau hauv acid, alkali, ntsev thiab lwm yam corrosive media yog tib yam li 321 stainless hlau, zoo welding kev kawm, yuav siv tau raws li corrosion-resistant khoom thiab anti. -corrosion Kub hlau yog tsuas yog siv nyob rau hauv thermal zog thiab petrochemical teb, xws li ua ntim, kav dej, tshav kub exchangers, shafts, rauv. tube nyob rau hauv industrial furnaces, thiab rauv tube thermometers.

10. 904L stainless hlau. Super tiav austenitic stainless hlau yog ib hom super austenitic stainless hlau tsim los ntawm OUTOKUMPU hauv Finland. , Nws muaj qhov zoo corrosion kuj nyob rau hauv non-oxidizing acids xws li sulfuric acid, acetic acid, formic acid thiab phosphoric acid, thiab kuj muaj zoo tsis kam mus crevice corrosion thiab kev nyuaj siab corrosion kuj. Nws yog haum rau ntau yam ntawm sulfuric acid hauv qab 70 ° C, thiab muaj corrosion kuj zoo nyob rau hauv acetic acid thiab sib tov acid ntawm formic acid thiab acetic acid ntawm tej concentration thiab kub nyob rau hauv ib txwm siab. Tus qauv qub ASMESB-625 cais nws raws li npib tsib xee-raws li alloys, thiab tus qauv tshiab cais nws li stainless hlau. Tsuas muaj cov qib zoo sib xws ntawm 015Cr19Ni26Mo5Cu2 steel hauv Suav teb. Ob peb lub tuam txhab nyob sab Europe siv 904L stainless hlau ua cov khoom tseem ceeb. Piv txwv li, lub ntsuas lub raj ntawm E + H qhov loj flowmeter yog ua los ntawm 904L stainless hlau, thiab rooj plaub ntawm Rolex watches kuj yog ua los ntawm 904L stainless hlau.

11. 440C stainless hlau. Martensitic stainless hlau muaj qhov nyuaj tshaj plaws ntawm cov hlau tsis muaj zog thiab cov hlau tsis muaj steel, nrog rau hardness ntawm HRC57. Feem ntau yog siv los ua nozzles, bearings, valve cores, valve rooj, tes tsho, valve stems, thiab lwm yam.

12. 17-4PH stainless hlau. Martensitic nag lossis daus hardening stainless hlau nrog hardness ntawm HRC44 muaj lub zog siab, hardness thiab corrosion kuj thiab tsis tuaj yeem siv ntawm qhov kub siab tshaj 300 ° C. Nws muaj kev tiv thaiv corrosion zoo rau cov cua thiab diluted acid lossis ntsev. Nws cov corrosion kuj yog tib yam li ntawm 304 stainless hlau thiab 430 stainless hlau. Nws yog siv los tsim cov platforms offshore, turbine blades, valve cores, valve rooj, tes tsho, valve stems tos.
