ISO 6164 4 Flange clamps, uas yuav tsum muaj cov khoom siv ferrous nrog cov khoom nram qab no hauv cov xwm txheej tas:
- Tsawg tshaj plaws tawm lub zog: 330 MPa;
- Tsawg kawg elongation ntawm pob txha: 5%.
ISO 6164 4 Flanged hau, uas yuav tsum muaj cov khoom ferrous nrog cov khoom nram qab no nyob rau hauv cov xwm txheej tas:
- Tsawg tshaj plaws tawm lub zog: 330 MPa;
- qhov tsawg kawg nkaus elongation ntawm pob txha: 10%.
ISO 6164 4 Screws. Tsuas yog hais tias tau teev, yuav tsum siv ib qho ntawm cov nram qab no:
