1.309s urwego rwicyuma
ikirango gihuye mubushinwa ni 06Cr23Ni13;Amercia Standard S30908, AISI, ASTM;JIS G4305 sus;Igipimo cy’iburayi 1.4833.
309s irimo sulfure yubusa gukata ibyuma bitagira umuyonga, bikoreshwa mugukata kubusa hamwe nubuso bwiza / busukuye busaba ibihe.
309 s ni bike bya karubone itandukanye ya 309 ibyuma bidafite ingese, gusudira bikoreshwa mubirori.Ibirimo bike bya karubone bikozwe muri zone yibasiwe nubushyuhe hafi ya weld mu mvura ya karbide kugeza byibuze, kandi bishobora kuviramo kugwa imvura ya karbide idafite ibyuma byangirika hagati yibidukikije (gusudira isuri).
2.309S Umwihariko
Irashobora kwihanganira ubushyuhe bukabije munsi ya 980 ℃, ifite imbaraga nyinshi hamwe no kurwanya okiside, ubushyuhe bwo hejuru bwa carburizing.
