P355 NL 2
Fine grained structural steel rau siab hlab ntsha. P355NL2 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 tank), cov hlab ntsha siab, qhov chaw rau chav boilers, siab piping, compressors, thiab lwm yam. }º.
P355NL2 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.

| Cov qauv zoo-grained ntawm P355NL2 steel ua rau nws haum rau cov ntawv thov kub. Cov pa roj carbon tsawg ntawm cov hlau txhim kho nws cov weldability, thaum muaj cov ntsiab lus alloying, xws li manganese, chromium, npib tsib xee, thiab molybdenum, txhim kho nws cov khoom siv kho tshuab, xws li lub zog thiab toughness. Cov tshuaj muaj pes tsawg leeg ntawm Welded Steel Tube P355NL2, EN-10217-3 yog tswj nruj me ntsis kom ntseeg tau tias cov hlau ua tau raws li qhov xav tau tshwj xeeb rau nws daim ntawv thov. Cov muaj pes tsawg leeg yuav txawv me ntsis nyob ntawm cov txheej txheem tsim khoom, tab sis tag nrho cov muaj pes tsawg leeg yog nyob rau hauv qhov kev teev tseg. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau feem ntau yog muab rau ntawm daim ntawv pov thawj zeb xeem, uas yog muab los ntawm cov chaw tsim khoom thiab nrog rau cov khoom thaum thauj thiab khaws cia. |
