Hom 904L yog lub siab alloy austenitic stainless hlau uas paub txog nws cov khoom corrosion. Qhov no qis carbon version ntawm Hom 904 stainless hlau kuj muaj lwm yam txiaj ntsig rau cov neeg siv xws li:
- Tsis-magnetic
- Cov khoom muaj zog corrosion dua li Hom 316L thiab 317L
- Zoo tsis kam rau sulfuric, phosphoric thiab acetic acids
- High tsis kam rau crevice thiab kev nyuaj siab corrosion cracking
- Zoo heev formability thiab weldability
Vim tag nrho cov txiaj ntsig ntawm kev siv hom 904L stainless hlau, nws tuaj yeem pom nyob rau hauv ntau daim ntawv thov hauv ntau yam kev lag luam tseem ceeb suav nrog:
- Cov khoom siv cua txias rau cov dej hiav txwv
- Kev ua tshuaj lom neeg ntawm sulfuric, phosphoric thiab acetic acids
- Kub exchangers
- Condenser tubes
- Gas ntxuav
- Tswj thiab ntsuas
- Kev lag luam roj thiab roj
- Kev tsim tshuaj
- Kev xaim hauv electrostatic precipitators
Yuav kom suav nrog Hom 904L, stainless hlau yuav tsum muaj cov tshuaj lom neeg tshwj xeeb uas suav nrog cov hauv qab no:
- Fe balance
- Yog '23-28%
- Cr 19-23%
- Mos 4-5%
- Mn 2%
- Cu S 1-2.0%
- Yog '0.7%
- S 0.3%
- N 0.1%
- P 0.03%
