1. Dab tsi yog tus yam ntxwv tseem ceeb ntawm P355N cov phiaj hlau?
Teb:
P355n yog anormonized zoo-lawed hlauNrog:
Yam tsawg kawg nkaus zog zog ntawm 355 mpa
Zoo tshajWeldability thiab tawv
Tsim rauDaim ntaub ntawv thov siab siabNtawm kev mob mentsis mus rau qhov kub tsawg
Feem ntau yog siv hauv thicknesses txog150 hli
2. Koj nyob li cas p355n haum rau?
Teb:
P355N yog pom zoo rau kev pabcuam tsis pub dhau:
Yam tsawg kawg nkaus kub: {-20 degree (nrog kev sib cuam tshuam)
Qhov kub tshaj plaws: 400 degree rau kev pabcuam txuas ntxiv
Cov qib tshwj xeeb muaj rau{{0 {}} degree lossis {-50 degreeNrog kev cuam tshuam ntxiv
3. Yuav tsum muaj kev kho cua sov li cas rau p355N daim phiaj?
Teb:
Yuav tsum muaj qhov ua tau zoontawm 890-950 degree
Cua txias txoj kev: Huab cua txias rau thickness tsawg dua los yog sib npaug rau 60 hli
For thickness >60mm:Nrhov cua txiastej zaum yuav tau
Tsis muaj kev lom zem thiab temperingtso cai rau qib no
