303 ndiro yesimbi isina tsvina
Kuwanda kwekushandisa: peturu, zvemagetsi, makemikari, mishonga, machira akareruka, chikafu, michina, kuvaka, simba renyukireya, aerospace, mauto uye mamwe maindasitiri! 303 isimbi yemahara-inochekwa isina tsvina ine sarufa uye selenium, zvichiteerana. Inonyanya kushandiswa mumashandisirwo apo kusununguka-kucheka uye kupedzisa kwepamusoro kunodiwa. 303 simbi isina tsvina inovandudza kucheka mashandiro uye yakakwirira tembiricha kuramba. Yakanakisa kune otomatiki lathes. Mabhoti nenzungu. 303 Stainless simbi ndeye austenitic yemahara-yekucheka-stainless kupfeka-resistant simbi. Kuti uvandudze kushanda kwesimbi iyi, molybdenum inogona kuwedzerwa kune simbi isingapfuuri 0.60 ﹪, iyo inogona kuramba kubviswa, uye chigadzirwa chine machinability yakanaka uye kupisa kuramba. Corrosion resistance. Mushure mekunge michina ye .303 simbi isina tsvina yakanyungudutswa uye yakaora mwoyo, simba rekusimba i515MPa, goho i205MPa, uye kureba i40%. Kuomarara kwesimbi isina tsvina 303 HRB 90-100, HRC 20-25, Cherechedza: HRB100 = HRC20 Nguva yekutumira: Ndira-19-2020
