Qhov txawv ntawm 1.4028 thiab 1.4021 yog dab tsi?

1.4021 stainless hlau yog dab tsi?

1.4021 stainless hlau (tseem hu ua X20Cr13 los yog AISI 420) yog ntau yam, hardenable martensitic stainless hlau muab cov neeg kho tshuab siab zog, zoo heev hnav tsis kam, thiab nruab nrab corrosion kuj. Nrog 12-14% chromium thiab 0.15-0.25% carbon, nws yog hlau nplaum, polishable heev, thiab feem ntau siv rau hauv cov khoom tawv thiab tempered rau cov cuab yeej, cutlery, twj tso kua mis, thiab fasteners, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas tsis yog-chloride.

 

1.4028 stainless hlau yog dab tsi?

1.4028 (X30Cr13 / AISI 420B) yog martensitic, cua sov- kho stainless hlau featuring kwv yees li 13% chromium thiab 0.30% carbon. Nws muaj cov hardness siab (kwv yees . 48-51} HRC) thiab hnav tsis kam, ua rau nws zoo tagnrho rau kev txiav cov cuab yeej, cov cuab yeej phais, thiab cov ncej, thaum muab cov tshuaj tiv thaiv tsis zoo hauv qhov tsis muaj - nruj.

 

Qhov txawv ntawm 1.4021 thiab 1.4028 yog dab tsi?

Thaum 1.4021 thiab 1.4028 zoo ib yam 420-qib martensitic stainless hlau, 1.4028 (420B) yog cov pa roj carbon ntau dua siv rau cov ntawv thov uas yuav tsum tau muaj zog dua, xws li cov cuab yeej phais, cutlery, thiab valve Cheebtsam, thaum 1.4021 (420B) yog qhov zoo dua rau cov khoom siv zoo dua thiab zoo dua rau cov khoom siv zoo.

1.4021 vs . 1.4028 Stainless hlau: Cov ntsiab lus carbon

1.4021 (X20Cr13) thiab 1.4028 (X30Cr13) yog ob qho tib si martensitic, 13% chromium stainless hlau, tab sis txawv feem ntau ntawm cov ntsiab lus carbon, uas cuam tshuam rau hardness thiab corrosion kuj. 1.4021 muaj qis dua carbon ntau (kwv yees . 0.16-0.25}%), muab cov pa roj carbon zoo dua (kwv yees . 0.26–0.35%), muab cov hardness zoo dua thiab hnav tsis kam.

1.4021 vs . 1.4028 Stainless Steel: Hardness/Strength

1.4028 stainless hlau feem ntau muab siab dua hardness thiab lub zog dua 1.4021 vim nws cov ntsiab lus carbon ntau dua (0.26–0.35% vs. 0.16–0.25%). Thaum 1.4021 (420A) ua tiav ib puag ncig 46-50 HRC, 1.4028 (420B) ncav cuag 50-54+ HRC tom qab kev kho cua sov. Ob leeg yog martensitic stainless hlau, tab sis 1.4028 yog qhov zoo dua rau hnav tsis kam thiab siv zog dua.

 

Yog 1.4021 magnetic?

1.4021 (tseem hu ua AISI 420 lossis X20Cr13) yog martensitic stainless hlau uas muaj zog sib nqus nyob rau hauv txhua yam kev mob, suav nrog annealed, quenched, thiab tempered xeev. Nws yog ib qho siab -chromium steel (12-14%) nquag siv rau cov ntawv thov uas xav tau ob qho tib si hnav thiab hlau nplaum, xws li cov cuab yeej, cutlery, thiab cov khoom siv.
