Uhlobo lwe-904L insimbi engagqwali ephezulu ye-alloy austenitic eyaziwa ngezakhiwo zayo zokugqwala. Le nguqulo yekhabhoni ephansi yohlobo lwe-904 yensimbi engagqwali iphinde inikeze ezinye izinzuzo kubasebenzisi ezihlanganisa:
- Okungewona uzibuthe
- Izakhiwo zokugqwala ezinamandla kunohlobo 316L no-317L
- Ukumelana kahle ne-sulphuric, phosphoric kanye ne-acetic acid
- Ukumelana okuphezulu nokuqhekeka nokuqhekeka kokugqwala kwengcindezi
- Excellent formability kanye weldability
Ngenxa yazo zonke izinzuzo zokusebenzisa i-Type 904L yensimbi engagqwali, ingatholakala kwinani lezinhlelo zokusebenza ezimbonini eziningi ezibalulekile ezihlanganisa:
- Imishini yokupholisa amanzi olwandle
- Ukucutshungulwa kwamakhemikhali kwe-sulphuric, phosphoric kanye ne-acetic acid
- Izishintshi zokushisa
- Amashubhu e-Condenser
- Ukugeza igesi
- Ukulawula kanye nezinsimbi
- Imboni kawoyela negesi
- Ukukhiqizwa kwemithi
- Izintambo kuma-electrostatic precipitators
Ukuze kubhekwe njengohlobo 904L, insimbi engagqwali kufanele ibe nokwakheka kwamakhemikhali okuhlukile okuhlanganisa okulandelayo:
- Fe ibhalansi
- Kuze kube ngu-23-28%
- Cr 19-23%
- Mo 4-5%
- Mn 2%
- I-Cu S 1-2.0%
- Si 0.7%
- S 0.3%
- N 0.1%
- P 0.03%
