Tshuaj muaj pes tsawg leeg
- Haum rau txias- tsim welded hollow seem ntawm cov tsis yog- alloy thiab nplua - cov qauv hlau. Zoo- cov hlau nplej tuaj yeem muaj Nb/V/Ti ntxiv (tag nrho cov ntsiab lus Tsawg dua lossis sib npaug li 0.12%).
| cov ntsiab lus % | C | Si | Mn | P | S | Cu | N | Cev |
| Cov ntsiab lus siab kawg | 0.22 | 0.55 | 1.60 | 0.035 | 0.035 | 0.55 | 0.012 | 0.45 |
| CEV= C+Mn/6+(Cr+Mo+V)/5+(Cu+Ni)/15; | ||||||||
|
Qhov ntsuas no ncaj qha txiav txim siab vuam kev ua tau zoo ntawm cov hlau; Tsawg dua lossis sib npaug li 0.45% tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem vuam ib txwm. |

Brisk Metalwork Co., ltd tsom rau kev tsim khoom thiab muab cov seem hollow thiab cov yeeb nkab steel
- Kev kho saum npoo: kub-dip galvanizing, hmoov txheej, lossis epoxy txau raws li kev tiv thaiv corrosion.
- Qhov cuam tshuam toughness qib 'JR' qhia tias cov khoom ua tau raws li qhov xav tau ntawm lub zog ntawm 20 degree. Rau cov tawv nqaij ntawm qhov kub thiab txias, cov qib nyob rau hauv tib tus qauv xws li S355J0 (0 degree) thiab S355J2 (-20 degree) tuaj yeem xaiv.
- Cov txheej txheem txias txias tuaj yeem ua rau me ntsis ua haujlwm tawv ntawm cov npoo ntawm qhov profile, uas yuav tsum tau muaj kev ntxhov siab tom qab- nyem annealing los txhim kho toughness (yeem raws li xav tau).
