Tsananguro pfupi:
Matavi esimbi isina ngura anoshandiswa mumaindasitiri akasiyana-siyana, anosanganisira kuvaka, kugadzira, mota, zvemuchadenga, nezvimwewo.
Mabhawa eSimbi Isina Kushanda:
Simbi isina ngura 403 isimbi isina ngura yemartensitic ine musanganiswa unosanganisira chromium, nickel, uye kabhoni shoma. Inozivikanwa nekudzivirira kwayo ngura munzvimbo dzine nyoro, kudzivirira kupisa kusvika 600°F (316°C), uye kusimba kwayo uye kuomarara. Simbi isina ngura 405 isimbi isina ngura yeferritic ine chromium uye nickel shoma. Inodzivirira ngura zvakanaka uye inogadzirwa zvakanaka. Haidziviri kupisa sedzimwe simbi dzisina ngura uye inowanzo shandiswa munzvimbo dzine ngura zvishoma. Simbi isina ngura 416 isimbi isina ngura yemartensitic ine sarufa yakawedzerwa, iyo inowedzera mashandiro ayo. Inodzivirira ngura zvakanaka, simba riri pakati nepakati, uye mashandiro akanaka kwazvo. Inowanzo shandiswa munzvimbo dzinoshandiswa machining emahara uye kudzivirira ngura zvakakosha.
