Daim ntawv foos:Xws li, phaj, ntawv, kauj, ntu, bar.
Tus xa khoom cov khoom / tus lej batch:Lub tshuab tsim cov cim hauv sab hauv rau cov khoom tshwj xeeb ntawm cov khoom tiav.
3. Tshuaj lom neeg muaj pes tsawg leeg (nrum tsom xam)
Daim ntawv pov thawj yuav tsum sau cov txiaj ntsig ntawm kev tsom ntsuas tshuaj lom neeg ua rau pom cov qauv thaum lub sijhawm yaj. Cov txiaj ntsig yuav tsum ua raws li cov kev txwv uas tau teev nyob rau hauvEN 10025-5.
Cov ntsiab lus tseem ceeb kom tau teev tseg:
Carbon (c)
Silicon (si)
Manganese (mn)
Phosphorus (p)
Sulphur (s)
Tooj Liab (Cu) - Tseem ceeb rau huab cua tsis kam
Chromium (cr) - Tseem ceeb rau huab cua tsis kam
Npib tsib caug (ni)
Kev xaiv cov ntsiab lus zoo li Vanadium (V), Niobium (NB), thiab lwm yam.
Qhov tseeb ntsuas qhov tseem ceeb rau txhua lub ntsiab yuav tsum tau muab, tsis yog cov lus hais ntawm kev ua raws.
4. Cov Khoom Siv Neeg Kho Tshuab
Cov txiaj ntsig ntawm kev ntsuam xyuas cov neeg kho tshuab ua rau cov qauv los ntawm cov khoom tiav. Qhov tseem ceeb yuav tsum ua kom tau raws li cov cai ntawm EN 10025-5 rau cov tuab tuab.
Paib lub zog (rov qab){{0- Ntsuas hauv MPa (piv txwv li, ntau dua lossis sib npaug rau cov tuab lossis sib npaug rau 16 hli)
Lub zog tensile (RM){{0- Ntsuas hauv MPa (piv txwv li, {{3,,6 mpa mpa)
Elongation (a){{0- Ntsuas hauv% (piv txwv li, ntau dua lossis sib npaug nrog 22% rau thickness 3mm {5} {mm)
Kev Cuam Tshuam Lub Zog (KV): Qhov no yog qhov tseem ceeb heev.
Sim ntsuas kub:Yuav tsum tau teev tseg (piv txwv li, -20℃lossis -40 kev kawm ntawv rau qib NH).
Absorbed Zog Tus Nqi:Qhov tseeb Joule nqi los ntawm Charpy V - tsis tau xeem (piv txwv li ntau dua lossis sib npaug ntawm -20 degree).
Orientation:Cov kev taw qhia ntawm cov hnoos qeev (ntev los yog transverse).
5. Kev xa khoom muaj kev mob & tshuaj xyuas
Seem no lees paub txog lub xeev ntawm cov khoom lag luam thiab dab tsi tau tshawb xyuas.
Kev Xa Khoom:Xws li, kub - rolled (+ n).
Nqe lus ntawm kev ua raws:Kev tshaj tawm meej tias cov khoom siv tau ua raws li qhov yuav tsum tau ua ntawm EN 10025-5.
