Kev kho cua sov

Cov txheej txheem kev kho cua sov feem ntau ntawm ss 304 tubing suav nrog:

normalizing

Tsis siv tau

Yog vim li cas: 304 tubing tsis tau txais txiaj ntsig los ntawm cov txheej txheem no.

Annealing

Kub:1010-1120℃(1850-2050℃F)

Txheej txheem:Ua kom sov rau qhov ntsuas kub, ces txias sai sai hauv huab cua lossis dej.

Quenching

Tsis pom zoo.

Yog vim li cas: quenching tsis tuaj yeem harden 304 tubing thiab tej zaum yuav ua rau distortion.

Tempering

Tsis siv tau.

Yog vim li cas: Tempering tsis muaj kev cuam tshuam vim 304 tubing tsis tuaj yeem hardened los ntawm quenching.
