Incoloy 825 seamless thiab welded yeeb nkabyog cov neeg hlau qhia thaum 316L lossis 254 SMO tsis tuaj yeem muaj sia nyob ntawm kev sib xyaw ntawm chlorides, acids, thiab qaub roj. Nws cov npib tsib xee- hlau-chromium puag, nrog rau kev txhob txwm molybdenum thiab tooj liab ntxiv, ua rau nws muaj zog tiv thaiv sulfuric thiab phosphoric acids, chloride stress- corrosion cracking, pitting, thiab qaub pab. Nws yog siv rau hauv kev tsim tshuaj, roj thiab roj, flue gas desulfurization, seawater txias, thiab marine systems thoob plaws Middle East thiab Europe.

Rau feem ntau refinery, tshuaj, thiab marine daim ntaub ntawv, ASTM B423 seamless yeeb nkab yog lub neej ntawd. ASTM B705 welded yeeb nkab raug xaiv thaum muaj qhov loj dua lossis cov phab ntsa nyias nyias. ASTM B163 / B704 tau teev tseg thaum cov khoom yog tubing rau cov khoom siv hluav taws xob los yog kev ntsuas.
Tshuaj muaj pes tsawg leeg (UNS N08825 / W.Nr. 2.4858)
| Lub ntsiab | Cov ntsiab lus (%) - ASTM B423 |
|---|---|
| Nickel (Ni) | 38.0 – 46.0 |
| Chromium (Cr) | 19.5 – 23.5 |
| Hlau (Fe) | 22.0 min |
| Molybdenum (hli) | 2.5 – 3.5 |
| Copper (Cu) | 1.5 – 3.0 |
| Titanium (Ti) | 0.6 – 1.2 |
| Cov pa roj carbon (C) max | 0.05 |
| Manganese (Mn) max | 1.0 |
| Silicon (Si) max | 0.5 |
| Sulfur (S) max | 0.03 |
Cov molybdenum thiab tooj liab ntxiv yog qhov txawv ntawm 825 los ntawm Incoloy 800 tsev neeg. Molybdenum txhim kho pitting thiab crevice corrosion kuj nyob rau hauv chlorides. Tooj liab txhim kho kev tiv thaiv rau sulfuric thiab phosphoric acids. Titanium stabilizes lub alloy tiv thaiv rhiab heev thaum vuam, uas yog vim li cas 825 feem ntau siv nyob rau hauv raws li -welded mob.
