- Dit (bor pa woko, lac pa ot)
- Steel grade (e.g., 1.4301, 1.4404)
- Kite mi cwalo (e.g., pii ma juyiko)
- Piny ma mitere pi neno (e.g., temo ma rac ungo, tegu pa pii)
- Piny moko ci ma mitere (e.g., leng pa piny ma pire tek pi tic mi nuclear).
Kite pa cuma & kit pa kemikol
Lembe ma jukwanu uketho i iye austenitic stainless steels, ikinde:
- Kite ma rwom: 1.4301 (304), 1.4404 (316L), 1.4541 (321), 1.4571 (316Ti), man mukende mapol.
