Cov Lus Nug: Dab tsi yuav tsum tau them sai sai thaum siv qhov khoom 904L?

904L yog ib qho qauv ua ib qho qauv austenite nrog High Ni thiab low C. Cov kab nrib pleb tau yoojyim rau hauv qhov vuam, tshwj xeeb tshaj yog hauv cov pits arc. Yog li ntawd peb yuav tsum them nyiaj rau cov lus qhia nram qab no.

1. Saib xyuas tus P, S thiab lwm cov ntsiab lus muaj kev phom sij hauv cov ntaub ntawv los luj.

2. Npog puab, me me fusion.

3. Siv cov khoom cua sov, tsis pub viav vias.

4. Qhov nruab nrab interlayer yuav tsum tsawg dua 60 ℃.

5.Cov ntim txuas kom txo cov kev txhawj xeeb.

6.Xaiv cov ntaub ntawv uas tsis muaj ntaub ntawv pov thawj tsawg.

7.Txhais ntawm tom qab tom qab sib tsoo kom tsis txhob muaj kab pleev kaub.

8. Yuav tsis pub rau sawv daws sab nraub qaum los tiv thaiv kom tsis txhob muaj teeb meem
