Simbi isina tsvina 304,304L,304H

Stainless simbi 304 uye Stainless simbi 304L inozivikanwawo se 1.4301 uye 1.4307 zvakateerana. 304 ndiyo inonyanya kushandiswa uye inoshandiswa zvakanyanya simbi isina tsvina. Ichiri dzimwe nguva inodaidzwa nezita rayo rekare 18/8 iro rinotorwa kubva muchimiro chezita re304 ichive 18% chromium uye 8% nickel. 304 Stainless simbi igiredhi reaustenitic rinogona kudhonzwa zvakadzika. Ichi chivakwa chakonzera kuti 304 kuve giredhi rinonyanya kushandiswa mumashandisirwo senge sink uye saucepan.

304L ndiyo yakaderera kabhoni vhezheni ye304. Inoshandiswa muheavy geji zvikamu zvekuvandudza kukwenenzverwa.

304H, yakakwira kabhoni yemukati musiyano, inowanikwawo kuti ishandiswe pakupisa kwakanyanya.
