P355NH chitsulo

EN 10028 P355NH/NL1/NL2
Chitsulo choponderezedwa chachitsulo chokhala ndi weldability wabwino komanso kukana kwambiri kusweka kwamphamvu, P355NH imagwiritsidwa ntchito ndi opanga padziko lonse lapansi kupanga akasinja otengera zotengera zosungiramo mpweya wopanikizika.

Mitundu ina yamakalasi ndi...
NL1 - ndi yabwino kuti igwiritsidwe ntchito kutentha kochepa
NL2 - ndiyoyenera kugwiritsidwa ntchito makamaka potentha kwambiri
P355NH ndi kalasi yachitsulo yokhazikika yokhala ndi mphamvu zokolola zochepa za 275-460 N/mm² ndipo mbale zimapezeka kale kuchokera kunkhokwe yathu.
