### 1. Cov khoom yog dab tsi yog cov khoom siv tshwj xeeb ntawm SA213?
** SA213 ** Yog ** ASTM Txheem ** Rau Seamless Ferritic thiab Austenic Alloy-{{{{}} Cov raj yog tsim Rau qhov kev pab kub-siab / siab (e {{13} g., fais fab nroj tsuag).
### 2. Yuav ua li cas qhia yog tias steel yog stainless lossis tsis?
Siv cov hau kev no:
- ** ** MOTERET TEST **: feem ntau ntawm cov hlau tsis muaj pa (tshwj xeeb tshaj yog Austenitic, e .} 2}}}},}},}, tsis muaj sib nqus **; Cov hlau zoo tib yam sib nqus . * Nco tseg: * Qee qhov cub ...}}, martensitic 410) yog sib nqus .
- ** Kev sim cais tawm **: Stainless hlau ua rau ** luv luv, reddish txim txim ** yam tsis muaj tawg; Pa roj carbon steel tsim kev ci ntsa iab, ntev ntev daj |.
- ** Kuaj tshuaj lom neeg **: Thov ** Nitric Acid **; Stainless hlau tiv taus corrosion (tsis muaj tshuaj tiv thaiv), thaum carbon steel corrodes .
- ** Saib saum npoo npoo
### 3. Puas muaj koob 9 stainless hlau?
** TSIS MUAJ {{.} "series 9" {} {} {}}}}} Thaum} Chromium (ntau dua los yog sib npaug rau 10 {. 5%) kom tau cais raws li stainless hlau.
### 4. yog series 9 stainless hlau zoo dua li ultra 2?
** Tsis sib piv - cov hom phiaj sib txawv: **
- ** series 9 (e {. g}, T91) **: Kev sib luag (tsawg dua lossis sib npaug corrosion tsis kam {}
- ** ALCTRA 2 **: Yuav muaj ** (e {{{{{{{{5} .
Rau corrosion / Acidic ib puag ncig **: ultra 2 (stainless 2 (stainless) yeej .
Rau cov creep resistance ntawm 600℃**: series 9 (T91) yeej .
### 5. yog series 9 titanium?
** TSIS MUAJ {.}} ... {{{}}}}} g {}}}}}}, qib 5, Ti -6 al -4 v) thiab tsis muaj hlau .
### Cov Ntsiab Tseem Ceeb:
- ** "series 9" ** {{= ferritic steel (e {} g}, T91) rau cov kev siv kub siab {}}
- ** Stainless hlau ** Yuav tsum muaj ntau dua lossis sib npaug rau 10 . 5% cr (e {} g}}}}}}}, 314, 314, 314, 314, 316).
- ** ALLTRA 2 ** yog ib txwm muaj tus hwm Stainless Alloy {2 2}}
- ** Titanium ** Yog qhov txawv txav tsis-ferrous hlau.
