Q: Dab tsi yog cov qauv qauv rau 2205 round kav?
A: ASTM A790: Txuj rau seamless thiab welded duplex stainless hlau kav.
ASTM A789 Txheem rau seamless thiab welded duplex stainless hlau tubing rau kev pabcuam dav dav.
TS EN 10216-5: Tus qauv European rau seamless stainless hlau raj rau lub hom phiaj siab.

Q2: Qhov txawv ntawm 316L thiab 2205 yog dab tsi?
Lub zog tawm los ntawm 2205 yog kwv yees li ob zaug ntawm 316L; qhov no tso cai rau txo cov phab ntsa tuab hauv kev tsim, yog li txo qhov hnyav tag nrho thiab tus nqi. PREN (Pitting Resistance Equivalent Number) ntawm 2205 feem ntau yog nyob nruab nrab ntawm 32 thiab 35, qhov ntawm 316L tsuas yog nyob ib ncig ntawm 24.

Q: Puas yog 2205 duplex stainless hlau round kav hlau nplaum?
A: Yog, lawv yog hlau nplaum. Vim tias 2205 muaj microstructure muaj kwv yees li 50% ferrite, nws nthuav tawm cov hlau nplaum tseem ceeb. Qhov no txawv ntawm qhov sib txawv ntawm 304/316 austenitic stainless hlau, uas tsis yog- sib nqus (lossis tsuas yog sib nqus tsis muaj zog).
