15-7M0Ph simbi alloy inogona kumira marudzi ese ekutonhora kuumba uye welding process pasi pemamiriro eaustenite.Zvadaro kuburikidza kupisa kurapwa anogona kuwana
simba gurusa;Pasi pe550 ℃ ine yakanakisa tembiricha yakasimba, yakagadzirirwa kuve nekuoma kukuru kupfuura 17-4 PH.The alloy is martensitic in structure in annealed condition uye inosimbiswazve neashoma tembiricha yekupisa kurapwa iyo inokonzeresa mhangura ine chikamu mune alloy.

•Inogona kumira marudzi ese ekutonhora kuumba uye welding process pasi pemamiriro e austenite.ipapo kuburikidza nekupisa kurapwa kunogona kuwana yakanyanya
simba, Pasi pe550 ℃ ine yakanakisa tembiricha simba.
•Magetsi welding midziyo: Simbi inogona kutora arc welding, resistance welding uye gasi rakadzivirirwa arc welding, gasi rakadzivirirwa welding ndiyo yakanyanya kunaka.
Welding inowanzoitwa mumidziyo yakasimba mhinduro yekurapa mamiriro, uye haifanire kudziya preheat isati yavekupisa.
Kana welding ichida simba rakawanda, iyo 17-7 ine yakaderera yemukati ye δ- ferrite inosarudzwa zvakanyanya, austenitic Stainless simbi welding waya inogona kushandiswa.
Inoshandiswa kugadzira avhiyesheni yakatetepa-madziro chimiro zvikamu, marudzi ese emidziyo, mapaipi, chitubu, valve firimu, chikepe shaft,
compressor ndiro, reactor zvikamu, pamwe neakasiyana ezvimiro zvemichina yemakemikari, nezvimwe.
