Hydrogen cia tso tsheb hlau luam: 316l vs . 21-6-9} cryogenic kev ua haujlwm

 

Vim li cas 316l tseem yog tus qauv rau chaw tso tsheb hlau luam loj?
Low-carbon 316L maintains >Hla 100-253℃.}}}}}} kev pom zoo rau 4.5 bar tsim kev siab.

 

Thaum nitrogen-expatened 21-6-9 yog teev?
Rau cov tso tsheb hlau luam hauv mobile xav tau 380 MPa tawm los lub zog {}}}}}} tso cai vs . 316 l.

 

Nyuaj kev tiv thaiv txoj kev?
Double vacuum melting reduces inclusions >20μm {{.}} ottm grain loj # 7 lossis finer {{} eecth. 4x mawp. Sib nqus permeability<1.02 at all production stages.

 

Kev soj ntsuam cov txheej txheem kev sim ua ntej?
Helium Bask tus nqi<1×10⁻⁷ mbar·L/s (static), <1×10⁻⁹ mbar·L/s (transport). Test duration: 1 hour per 10m³. Acoustic emission monitoring during cooldown.

 

Txias cov txheej txheem sib dhos?
