EN10216-5 Cov Hlau Tsis Muaj Qhov Txuas Rau Lub Hom Phiaj Siab Ntawm Qhov Kub Siab - Cov Kev Cai Xa Khoom Siv
Cov Ntaub Ntawv Txog Kev Txiav Txim
Cov neeg yuav khoom yuav tsum qhia meej tias:
- Qhov ntau (ntev, tus naj npawb ntawm cov raj)
- Qhov ntev (txheej sab nraud, phab ntsa tuab)
- Qib hlau (piv txwv li, 1.4301, 1.4404)
- Kev xa khoom (piv txwv li, cov tshuaj annealed)
- Cov kev cai tshuaj xyuas (piv txwv li, kev sim tsis ua puas tsuaj, kev siab hydrostatic)
- Tej yam yuav tsum tau ua tshwj xeeb (piv txwv li, kev huv tshwj xeeb rau kev siv nuclear).
Cov Qib Hlau & Cov Tshuaj Lom Zem
Tus qauv no suav nrog cov hlau tsis xeb austenitic, suav nrog:
- Cov qib txheem: 1.4301 (304), 1.4404 (316L), 1.4541 (321), 1.4571 (316Ti), thiab lwm yam.
- Cov qib kub siab: 1.4919, 1.4958, thiab lwm yam.
- Cov kev txwv ntawm cov khoom sib xyaw rau C, Si, Mn, P, S, Cr, Ni, Mo, N, thiab lwm yam, tau teev tseg.
Cov Cai Tsim Khoom & Kev Xa Khoom
- Txoj kev tsim khoom: Seamless, txias / kub tiav.
- Kev kho cua sov: Kev ua kom cov kua kub (yuav tsum muaj rau cov hlau austenitic).
- Qhov chaw tiav: Tsis muaj nplai, tawg, thiab qhov tsis zoo; tej zaum yuav xav tau pickling lossis passivation.
Kev Tshuaj Xyuas & Kev Ntsuas Cov Kev Cai
1 Cov Khoom Siv Kho Tshuab
- Kev sim tensile (Rm, Rp0.2, elongation)
- Kev kuaj qhov nyuaj (yog tias xav tau)
2 Kev Ntsuas Tsis Ua Rau Puas Tsuaj (NDT)
- Kev kuaj eddy tam sim no lossis ultrasonic rau kev kuaj pom qhov tsis zoo.
- Kev kuaj hydrostatic (xaiv tau, tshwj tsis yog teev tseg).
3 Lwm Yam Kev Ntsuas
- Kev ntsuas qhov loj ntawm cov noob (rau qee qib)
- Kev sim xeb intergranular (piv txwv li, Strauss sim rau kev ua kom hnov mob).
Kev Cim Npe & Daim Ntawv Pov Thawj
- Cov raj yuav tsum muaj cim nrog:
- Lub npe/logo ntawm tus neeg tsim khoom
- Qib hlau
- Qhov Loj
- Tus lej cua sov
- Tus qauv siv (EN 10216-5).
- Daim Ntawv Pov Thawj Tshuaj Xyuas 3.1 lossis 3.2 (EN 10204).
Kev kam rau siab & Qhov ntev
- Npog qhov kam rau ua rau sab nraud txoj kab uas hla, phab ntsa tuab, ncaj, thiab ntev.
