4.1.4303 stainless hlau thiab 305 stainless hlau: corrosion tsis kam & cov ntawv thov
General corrosion tsis kam:
Cov kev ua tau zoo sib xws hauv cov huab cua, dej, thiab ib puag ncig kev sib ze.
Viav Vuam Scararios:
1.4303 cov pa roj roj tsawg zaus muaj kev pheej hmoo corrosion-vuam, tsis muaj kev kho cua sov, tsis muaj kev kho cua sov.
305 yuav tsum ceev faj rau vuam vim ntau dua cov pa roj carbon ntau dua.
Kev Kub-Kub Oxidation:
3 {0 5 lub qis dua si (tsawg dua lossis sib npaug nrog 0.75%) muaj cov oxidation zoo dua li 600 degree.

5. Interchangeability
Tuaj yeem hloov pauv thaum:
Tsis-welded, chav-hluav taws xob ib puag ncig (piv txwv li, archectural luas, qhov chaw txias-tsim).
Cov ntsiab lus carbon cov ntsiab lus tsis nruj (piv txwv li, cov qauv uas tso cai tsawg dua lossis sib npaug}. 12% c).
Tsis tuaj yeem hloov pauv thaum:
Welded qauv (1.4303 cov pa roj carbon ntau yog qhov tseem ceeb rau corrosion tsis kam).
High temperatures (>600 degree) lossis cov tshuaj oxidizing heev (305's qis dua zoo dua oxidation tsis kam).
Cov Qauv tshwj xeeb tau muab qhab nia ib qib (piv txwv li, en 10088-2 rau 1.4303 lossis ttm A240 rau 305).
6.1.4303 stainless hlau thiab 305 stainless hlau: nqi & ua haujlwm
Nqi:
1.4303 yog me ntsis kim dua (tsawg dua los yog sib npaug rau 5% hwm tau) vim cov khoom siv roj carbon tsawg.
Ua haujlwm:
Txias tsim: ob qho zoo hauv kev sib sib zog nqus thiab kiv.
Vuam: 1.4303 muaj cov kev tswj kom zoo dua weldability (tsis txhob txhawb qhov kub uas xav tau); 305 Yuav tsum muaj cov tshev corrosion weld.
Machining: me ntsis sib txiav tsis kam nyob rau hauv 305 vim muaj cov roj carbon ntau dua, tab sis qhov sib txawv yog tsawg heev.
