P355NL1 steel welded yeeb nkab
P355NL1
Fine grained structural steel rau siab hlab ntsha. P355NL1 steel yog tus cwj pwm los ntawm kev sib txuas zoo thiab kev ua haujlwm siab kom tawg tawg. Cov hom no yog siv saum toj no tag nrho rau kev tsim cov hlab ntsha rau cov pa roj (LPG, butane thiab propane tso tsheb hlau luam), cov hlab ntsha siab, qhov chaw rau chav boilers, siab piping, compressors, thiab lwm yam. }º.
P355NL1 steel yog muab nyob rau hauv lub normalized mob. Lub normalizing kub yog 900 - 950 ºC, thiab nws yuav tsum tau muab tso rau hauv lub cub tawg tom qab kub sib npaug zos rau kwv yees li 1 feeb ib millimeter thickness ntawm lub phaj. Yog li ntawd, nws muaj qhov zoo txias-forming thiab kub-forming zog yam tsis muaj qhov tsis zoo rau cov khoom siv.
Cov hlau zoo grained hauv cov koob no tuaj yeem ua tau zoo kawg nkaus welded, ob qho tib si manually thiab siv cov khoom siv tsis siv neeg, los ntawm txhua qhov kev paub vuam txheej txheem.
