Ngec me lwongo
Luwil omyera gu lok:
- Wel (bor, wel tube)
- Kit (dit ma woko, pek pa cel)
- Kit me nyonyo (labol, 1.4301, 1.4404)
- Kit ma ki cwalo kwede (me labolle, gin ma ki lwongo ni analed)
- Jami ma mite me neno (me labolle, temo ma pe balo jami, teko pa pii)
- Gin mo keken ma mite (me labolle, lengo ma pire tek pi tic ki nuclear).
rwom me nyonyo ki kit ma ki yubu kwede
Gin ma ki keto ni kwako jami ma ki lwongo ni austenitic stainless steels, medo ki:
- rwom ma opore: 1.4301 (304), 1.4404 (316L), 1.4541 (321), 1.4571 (316Ti), ki mukene.
- rwom me lyeto ma malo: 1.4919, 1.4958, ki mukene.
- Ki keto rwom me C, Si, Mn, P, S, Cr, Ni, Mo, N, ki mukene.
Kit me yubu ki cwalo jami
- Kit me yubu ne: Labongo goro, ki tyeko ki ngiico/lyet.
- Tic ki lyeto: keto gin ma ki lwongo ni Solution annealing (ma miite pi austenitic steels).
- Kit ma ki yubu kwede: Pe ki buru, buru, ki goro; keto gin ma ki lwongo ni pickling onyo passivation twero bedo gin ma mite.
Gin ma mite me neno ki temo
1 Kit ma jami tiyo kwede
- Temo teko (Rm, Rp0.2, dongo)
- Temo tek (ka mitte)
2 Non-Destructive Testing (NDT)
- Eddy current onyo ultrasonic testing me nongo peko.
- Temo jami ma pii mol iye (labongo miite, kono pi ki waco).
3 Temo mukene
- Pimo dit pa nyig cam (pi rwom mogo)
- Temo jami ma ki lwongo ni intergranular corrosion (me labolle, temo me Strauss pi miyo teko).
keto lanyut ki miiyo twero
- Tube omyera ki coc iye:
- Nying/lanyut pa layub jami
- rwom me nyonyo
- Dit
- Namba me lyeto
- Gin ma ki ngeyo (EN 10216-5).
- Karatac me neno 3.1 onyo 3.2 (EN 10204).
Diyo cwiny ki dit pa jami
- Umo rwom me rwate pi dit pa cel, pek pa cel, rwom me atir, ki borre.
