ib.Tag nrho cov txiaj ntsig yog qhov tseem ceeb tshaj plaws tshwj tsis yog cov qhia.b.Nyob rau hauv rooj plaub ntawm kev tsis sib haum xeeb D. siv rau cov khoom tsom xam D. siv rau

(3) Selenium tuaj yeem siv los hloov cov sulfur, tab sis nws txoj kev siv yuav raug txwv.

d.Yog tias qhov loj feem ntawm npib tsib xee tsawg dua 8%, qhov tsawg kawg nkaus feem ntawm manganese yuav tsum yog 5%.

e.Thaum qhov loj feem ntawm npib tsib xee ntau dua 8%, cov ntsiab lus tooj liab yam tsawg kawg yog tsis txwv.

f.Molybdenum cov ntsiab lus yuav tshwm sim hauv cov chaw tsim khoom cov lus qhia.Txawm li cas los xij, rau qee yam kev siv, yog tias tsim nyog los txwv cov ntsiab lus molybdenum, nws yuav tsum tau qhia los ntawm tus neeg siv hauv daim ntawv xaj.

④, ib.Yog tias qhov loj feem ntawm chromium tsawg dua 17%, qhov tsawg kawg nkaus feem ntawm npib tsib xee yuav tsum yog 12%.

h.Austenitic stainless hlau nrog ib pawg loj ntawm 0.03% carbon thiab ib feem ntawm 0.22% nitrogen.

⑤, ib.Rau cov khoom lag luam loj dua, cov chaw tsim khoom cov lus qhia yuav muaj cov ntsiab lus carbon ntau dua kom ua tiav cov khoom siv kho tshuab, tab sis nws yuav tsum tsis pub tshaj 0.12% rau Austenitic steel.

⑥, ib.Titanium thiab / lossis niobium tuaj yeem suav nrog txhawm rau txhim kho corrosion.

⑦, ib.Cov mis no tsuas yog siv rau lub hom phiaj ntawm kev faib cov duplex steels raws li daim ntawv no (nws tsis yog tsim los siv los ua kev xaiv rau kev tiv thaiv corrosion).
