ASTM A210 yog dab tsi
ASTM A210 yog tus qauv tshwj xeeb rau seamless nruab nrab - carbon steel boiler raj thiab superheater tubes. Nws yog cov khoom siv dav siv rau boiler raj, superheaters, thiab cov khoom siv hluav taws xob sib txawv hauv cov khoom siv hluav taws xob thiab cov chaw tsim khoom. Tsis zoo li A192, A210 npog ntau cov qib carbon steel, nrog rau nruab nrab -carbon thiab carbon-manganese steels nrog lub zog siab dua.
Ob Qib Siab
Qib A-1 yog qhov nruab nrab- carbon steel thiab tus qauv qib rau kev pabcuam boiler, siv rau cov raj boiler dav dav thiab kev lag luam. Qib C yog cov pa roj carbon-manganese steel muab siab dua tensile thiab yield zog, siv rau superheater raj thiab kub-kub seem uas yuav tsum tau muaj zog dua.
Tshuaj muaj pes tsawg leeg
| Element | Qib A-1 (%) | Qib C (%) |
|---|---|---|
| Cov pa roj carbon | 0.13 - 0.19 | 0.24 - 0.31 |
| Manganese | 0.37 - 0.65 | 0.84 - 1.15 |
| Phosphorus, max | 0.035 | 0.035 |
| Sulfur, max | 0.035 | 0.035 |
| Silicon, min | 0.10 | 0.10 |
Mechanical Properties
Qib A-1 muaj lub zog tensile yam tsawg kawg nkaus ntawm 415 MPa (60,000 psi), qhov tsawg kawg nkaus yield zog ntawm 255 MPa (37,000 psi), thiab qhov tsawg kawg nkaus elongation ntawm 30 feem pua ntawm 50 hli. Qib C muaj lub zog tensile yam tsawg kawg nkaus ntawm 485 MPa (70,000 psi), qhov tsawg kawg nkaus yield zog ntawm 275 MPa (40,000 psi), thiab qhov tsawg kawg nkaus elongation ntawm 30 feem pua.
Kev sib piv nrog ASTM A192
A192 yog rau yam tsawg kawg nkaus -phab ntsa-thickness, qis- carbon steel hlab feem ntau rau siab - dej siab- raj boilers. A210 yog rau tus qauv-phab ntsa, nruab nrab- cov pa roj carbon lossis siab dua- cov raj muaj zog siv hauv boilers thiab superheaters qhov twg yuav tsum muaj zog ntau dua, tshwj xeeb tshaj yog nyob rau qhov kub siab. Qib C yog lwm txoj hauv kev rau A192 thaum xav tau lub zog siab dua.
