1.309s kowiri tira kōeke
tohu rite i roto i Haina ko 06Cr23Ni13;Amercia Paerewa S30908, AISI, ASTM;JIS G4305 paerewa sus;Paerewa Pakeha 1.4833.
Kei roto i te 309s he whanariki kore utu tapahi kowiri tira, whakamahia mo te tapahi kore utu matua me te mata kanapa/ma e hiahia ana.
Ko te 309 s he iti nga rereketanga o te waro o te 309 he kowiri tira, ka whakamahia te whakapiri ki te waa.He iti te waro ki roto i te rohe wera e tata ana ki te weld i roto i te rerenga o te carbide ki te iti rawa, a tera pea ka puta te rerenga o te carbide he kowiri tira te waikura intergranular i etahi taiao (he welding erosion).
2.309S Motuhake
Ka taea e ia te tu atu i te whakamahana i raro i te 980 ℃, he kaha ake te kaha me te aukati o te waiora, te mahi carburizing teitei.
