Cov kev sim twg yog siv los txheeb xyuas P460QL1 qhov zoo?
Kev ntsuam xyuas zoo rau P460QL1: tensile (yield, tensile, elongation), Charpy V-notch impact (-40 degree, 60 J min), Brinell/Rockwell hardness, chemical analysis (OES/XRF), and NDT (UT/MT/PT for defects). Cov neeg tsim khoom ua cov no thaum tsim khoom; Cov neeg yuav khoom tuaj yeem rov tuaj xyuas dua kom ntseeg tau tias EN 10025-6 ua raws.
Dab tsi yog qhov kev txiav txim siab ib puag ncig thaum siv P460QL1?
P460QL1 ntau lawm eits tsev cog khoom gases- siv cov khoom siv rov qab los txo qhov cuam tshuam. Recyclable heev; txoj kev npaj kawg- ntawm- pov tseg lub neej kom tsis txhob xeb / txheej txheej. Fabrication (welding / machining) xav tau qhov cua / khib nyiab rau fumes / particulates. Siv eco-coatings tus phooj ywg txheej (dej- pleev xim) thiab tsim rau cov khoom siv tau zoo ntawm lub zog siab.
Puas yog P460QL1 weldable?
Yog lawm, P460QL1 yog weldable nrog cov txheej txheem kom raug. Tsawg carbon sib npaug (tsawg dua lossis sib npaug li 0.45) txo qis qhov txias txias. Recommended method: SMAW, GMAW/MIG, GTAW/TIG, SAW. Preheat (80-150 degree) rau ntau dua lossis sib npaug li 12 hli thickness lossis PWHT tej zaum yuav xav tau rau qhov tuab / qhov tseem ceeb. Siv cov hluav taws xob tsawg-hydrogen electrodes/filler hlau sib piv lub zog.
