| Neeg Kho Tshuab Muaj Zog | Siab dua | Qi dua |
| Ua haujlwm Temp ntau | Txog li ~ 500 degree | Tsawg xav tau ib puag ncig |
🔎 Lub ntsiab: A181 yog cov qib qis forged carbon hlau rau cov tshuab hluav taws xob tsawg. A105 yog ntau ntau yam.
4️⃣ ASTM A105 VS ASTM A234
| Yam zoo | ASTM A105 | ASTM A234 |
|---|---|---|
| Kev tsim khoom | Tiv thaiv | Tau tawm |
| Daim ntawv thov | Flanges, fittings | Taub qab-weld yeeb nkab fittings |
| Khoom Hom | Forged carbon hlau | WPB (Wrought Carbon Hlau) |
🔎 Lub ntsiab: A105 yog siv rau forged fittings, A234 (tshwj xeeb yog WPB qib) yog siv rau pob tw-Weld fittings.
5️⃣ ASTM A105 VS ASTM A216 WCB
| Yam zoo | ASTM A105 | ASTM A216 WCB |
|---|---|---|
| Kev tsim khoom | Tiv thaiv | Khoom puab hlau |
| Cov ntaub ntawv ntau | Flanges, fittings, li qub | Valve Lub Cev, Flanges |
| Nto | Zoo dua vim forging | Tej zaum yuav muaj casting qhov tsis xws luag |
| Cov Khoom Siv Neeg Kho Tshuab | Muaj zog, denser | Me ntsis qis dua |
🔎 Lub ntsiab: A216 WCB yog cov hlau nplaum. A105 yog forged - zoo dua rau kev sib khi tseem ceeb thiab lub zog.
6️⃣ ASTM A350 LF2 VS ASTM A105
| Yam zoo | ASTM A105 | ASTM A350 LF2 |
|---|---|---|
| Temp ntau | -29 degree thiab siab dua | -46 degree thiab siab dua |
| Low-temp tawv | Tswj kav | Zoo tshaj |
| Kev Kho Cua Sov | Yam ua tau | Yuav tsum tau (li qub thiab tempered) |
| Siv cov ntaub ntawv | Cov Flanges | Cryogenic thiab qis-temp flanges |
🔎 Lub ntsiab: A350 LF2 yog kev mus xaiv rau kev pabcuam kub-ntsuas; A105 yog dav dav-lub hom phiaj.
7️⃣ AISI 1018 VS ASTM A105
| Yam zoo | ASTM A105 | AISI 1018 |
|---|---|---|
| Cov ntsiab lus carbon | ~0.35% | ~0.18% |
| Lub zog | Siab dua | Qi dua |
| Kev siv | Lub Cheeb Tsam | Tshuab siv tshuab, cov qauv sib luag |
| Luam ntawv | Zoo | Zoo tshaj |
🔎 Lub ntsiab: AISI 1018 yog hlau me rau machining; A105 yog ib qib forging kom muaj zog.
8️⃣ ASME SACH5 VS ASTM A105
| Yam zoo | ASTM A105 | ASME SA35 |
|---|---|---|
| Kev Siv Cov Qauv | ASTM (dav dav) | ASME BOILER & SIAB NTSHEL CODE |
