S355JOH Mechanical Properties

Simba shoma regoho rinosvika 355 MPa;

Tensile simba kukosha 510 MPa kusvika 680 MPa;

Hurefu hwayo hudiki hunowanzodikanwa kuti huve kupfuura 20 muzana;

Izvo zvinofanirwa kucherechedzwa kuti kurebesa kunogona kukanganiswa nehukuru hwemuenzaniso, chimiro, uye mamiriro ekuyedzwa, saka mune chaiwo mainjiniya maapplication, zvingave zvakafanira kutarisa kune yakadzama zviyero kana kutarisa nemupi wezvinhu kuti uwane data rakarurama.

Kushivirira kweOuter Diameter (D)

Kune madhayamita ekunze asiri makuru kupfuura 168.3mm, kushivirira kuri ± 1% kana ± 0.5mm, chero yakakura.

Kune dhayamita yekunze yakakura kupfuura 168.3mm, kushivirira kuri ± 1%.

Rusvingo Ukobvu (T) Kushivirira

Kushivirira kwemadziro ekushivirira zvichienderana nehukuru chaihwo uye giredhi ukobvu hwemadziro (sezvinoratidzwa patafura), kazhinji mu ± 10% kana zvakadaro, kuitira kunyatso kudzora kwemadziro ukobvu maapplication, kungangoda kurongeka kwakakosha.

Kushivirira Kwekureba

Kushivirira kwehurefu hwakajairika (L) ndeye -0/+50mm.

Kune hurefu hwakatarwa, kushivirira kunowanzo ± 50mm.

hurefu chaihwo kana hurefu chaihwo hunogona kunge hwakaomarara kushivirira zvinodiwa, izvo zvinoda kutemerwa mukubvunzana nemugadziri panguva yekuraira.

Kuwedzera Kushivirira kweSikweya uye Rectangular Zvikamu

Sikweya uye rectangular zvikamu zvine kunze kwekona radius kushivirira kwe2T, uko T ndiko ukobvu hwemadziro.

Kushivirira kweDiagonal Difference

Ndiko kuti, kukosha kwakanyanya kwekusiyana pakati pehurefu hwemadiagonal maviri ezvikamu zvekwere uye rectangular, kazhinji haisi kupfuura 0.8% yehurefu hwose.

Kushivirira kweRight angle uye Twisting Degree

Kushivirira kwekutwasanuka (kureva, kudzika kwechikamu) uye kumonyoroka (kureva kuti, kupfava kwechikamu) kunotsanangurwawo zvakadzama muchiyero kuti ive nechokwadi chechimiro chechimiro uye chitarisiko chose.
