C22 alloy thiab 20 Alloy phaj muaj kev sib piv corrosion
Cov Sulfuric Acid Ib puag ncig:Hauv cov sulfuric acid nrog lub siab ntawm tsawg dua lossis sib npaug nrog 7 {{{{{{{{{{9 {9}}. 1 hli. Txawm li cas los xij, nyob rau hauv lub rhaub 10% sulfuric acid ib puag ncig, cov corrosion acid ib puag ncig, muaj peev xwm tswj tau ntau dua li 0.30 molybdenum tus nqi tsawg dua los yog sib luag rau 0.1 mm \/ xyoo.
Hydrochloric acid thiab lwm yam txo cov acids:Hauv kev txo cov acid acid, hauv hydrochloric acid muaj cov chloride (ntau dua los yog sib npaug lossis sib npaug) Rau cov sib xyaw ua ke acid, lub siab alloy muaj pes tsawg leeg ntawm C22 muab ib qho kev ua haujlwm dav dav, thaum Alloy 20 yuav ntsib kev pheej hmoo corrosion loj.
Alloy 20 Steel Phaj thiab N06020 Steel Phaj Nrig Corrosion Kuj
Pitting thiab crevice corrosion:Hastelloy C22 muaj qhov ntsuas kub tseem ceeb (CPT ntau dua lossis sib npaug ntawm 85 degree) thiab muaj kev sib npaug heev los yog sib npaug yog txog {{4 4}} degree). Nyob rau hauv seaterwater lossis high chloride ion ib puag ncig, C22 daim hlau tuaj yeem siv nyab xeeb rau hauv cov kev mob hauv qab 85 degree, Thaum Alloy 20 tsuas yog tsim nyog rau ib puag ncig hauv qab 50 degree.
Kev ntxhov siab corrosion cracking (SCC):Hastelloy C22 showed no signs of cracking in 25% NaCl + 0.5% H₂S solution at 80°C tested according to NACE TM0177 standard. Alloy 20 relies on its 33% nickel content to provide good resistance to chloride ion stress corrosion, which is better than 304/316 stainless steel, but it may still crack in high temperature (>80 DEGREE) THIAB KEV ZOO TSHAJ PLELRORIDE OCRUG.
