Dab tsi yog 1.4547 khoom sib npaug?

1.4547 (tseem hu ua UNS S31254, 254 SMO, thiab SS2378) yog siab- alloy austenitic stainless hlau nrog zoo corrosion kuj. Piv nrog rau cov hlau tsis zoo tib yam, 1.4547 nthuav tawm cov kev tiv thaiv zoo tshaj plaws rau cov corrosion tsis zoo, tshwj xeeb tshaj yog nyob rau hauv acidic media uas muaj halogens. Nws muaj cov ntsiab lus siab ntawm alloying ntsiab, uas muab cov hlau no zoo heev rau pitting thiab crevice corrosion. Tsis tas li ntawd, cov hlau no tseem muaj kev tiv thaiv zoo heev rau kev ntxhov siab corrosion cracking.

 

1.4547 cov khoom (tus qauv European) yog siab - alloy austenitic stainless hlau, sib npaug rau UNS S31254 (American standard), feem ntau hu ua 254 SMO (hom npe / lub npe npe), ASTM F44 (forgings), thiab X1CrNiMoCuN20 (tus qauv).

Dab tsi yog qhov hardness ntawm 1.4547 stainless hlau?
1.4547 stainless hlau (254 SMO) tsis yog cua sov- kho tau rau hardening thiab, nyob rau hauv cov kev daws teeb meem -annealed mob, feem ntau pom ib tug hardness ntawm tsawg dua los yog sib npaug rau 220 HB (≈90 HRB), muab qhov sib npaug ntawm lub zog siab thiab zoo heev ductility es tsis hnav tsis kam.

 

Dab tsi yog qhov ntom ntawm 1.4547 stainless hlau?
Qhov ceev ntawm 1.4547 stainless hlau yog kwv yees li 8.0 g / cm³ (8,000 kg / m³), ​​zoo ib yam li lwm yam siab -alloy austenitic stainless hlau, txhawb nws siv hauv cov qauv thiab siab- cov ntawv thov uas tsis muaj qhov hnyav hnyav piv rau 316L.

 

Dab tsi yog qhov txawv ntawm 1.4547 thiab 1.4545 stainless hlau?

1.4547 (254 SMO) yog super austenitic stainless hlau uas muaj cov qib molybdenum siab heev (kwv yees li 6%) thiab nitrogen, nrog PREN tus nqi kwv yees li 42-45. Nws muaj kev tiv thaiv zoo heev rau chloride pitting corrosion, crevice corrosion, thiab seawater corrosion. Hauv qhov sib piv, 1.4545 (17{13}}4PH) yog cov nag lossis daus-tawv tawv stainless hlau nrog lub zog tensile txog li ntawm 1,300 MPa tom qab kev laus kev kho mob, tab sis nws tsis kam mus rau chloride corrosion yog txo qis dua li ntawm 1.4547. Yog li ntawd, 1.4547 yog qhov tsim nyog rau qhov chaw muaj corrosive heev, thaum 1.4545 yog qhov tsim nyog rau kev siv tshuab ua haujlwm siab.
