Thayipha i-440 Stainless Steel, eyaziwa ngokuthi "insimbi yensingo," iyinsimbi eqinile ye-carbon chromium. Uma ifakwa ngaphansi kokwelashwa ngokushisa ifinyelela amazinga aphezulu obulukhuni anoma yiliphi ibanga lensimbi engagqwali. Uhlobo lwe-440 Stainless Steel, oluza ngamamaki amane ahlukene, 440A, 440B, 440C, 440F, lunikeza ukumelana nokugqwala okuhle kanye nokumelana nokuhuzuka. Wonke amamaki angenziwa ngomshini kalula esimweni sawo se-annealed, aphinde anikeze ukumelana nama-acids athambile, ama-alkali, ukudla, amanzi ahlanzekile, nomoya.

Ngenxa yezakhiwo ezivelele zebanga ngalinye, wonke amabanga ohlobo lwe-440 Stainless Steel angatholakala kwinani lemikhiqizo ehlukene okuhlanganisa:
- Izikhonkwane ze-Pivot
- Amazinyo kanye nezinsimbi zokuhlinza
- Izinsimbi zommese ezisezingeni eliphezulu
- Izihlalo zamavalvu
- Imilomo
- Amaphampu kawoyela
- Ama-elementi agingqayo
Ibanga ngalinye le-Type 440 Stainless Steel lakhiwe ukwakheka kwamakhemikhali okuhlukile. Kufanele kuqashelwe ukuthi umehluko omkhulu kuphela phakathi kwamabanga izinga leCarbon
