Txheej txheem cej luam: Dab tsi yog 16Mo3?
16m3 yogqis- hlau alloycais raws li European tus qauvTS EN 10216-2. Lub "Mo" hauv nws lub npe sawv cev rau Molybdenum, uas yog qhov tseem ceeb ntawm cov hlau alloying uas muab cov hlau no zoo dua qub piv rau cov pa roj carbon monoxide.
Nws yog tsim tshwj xeeb rausiab -kev pabcuam kub, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov nroj tsuag hluav taws xob, boilers, thiab cov hlab ntsha siab.
Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg yog nruj me ntsis tswj los xyuas kom meej kev ua tau zoo. Qhov ntau yam yog raws li EN 10216-2:
| Lub ntsiab | Cov ntsiab lus (%) |
|---|---|
| Cov pa roj carbon (C) | 0.12 - 0.20 |
| Silicon (Si) | Tsawg dua lossis sib npaug li 0.35 |
| Manganese (Mn) | 0.40 - 1.00 |
| Phosphorus (P) | Tsawg dua lossis sib npaug li 0.025 |
| Sulfur (S) | Tsawg dua lossis sib npaug li 0.010 |
| Molybdenum (hli) | 0.25 - 0.35 |
| Chromium (Cr) | Tsawg dua lossis sib npaug li 0.30 |
Key Takeaway:Cov ntsiab lus ntawm cov pa roj carbon tswj tau muab qhov zoo weldability, thaum qhov sib ntxiv molybdenum ua rau muaj zog thiab nkag siab ntawm qhov kub siab.
Mechanical Properties
Cov khoom siv kho tshuab tau lees paub los ntawm cov chaw tsim khoom thiab tshawb xyuas los ntawm kev sim. Rau cov kav dej xa hauv cov xwm txheej zoo li qub (lub xeev feem ntau):
| Khoom | Tus nqi |
|---|---|
| Yield zog (Rp0.2 Min) | 270 MPa |
| Tensile zog (Rm) | 450 - 600 MPa |
| Elongation (A) | Ntau dua lossis sib npaug li 22% |
Cov yam ntxwv tseem ceeb & qhov zoo
Zoo heev High -Temperature Strength:Qhov zoo tshaj plaws . 16Mo3 khaws nws lub zog txhua yam ntawm qhov kub thiab txias qhov twg carbon steel yuav pib tsis muaj zog (feem ntau siab dua 400℃/ 750℃F).
Zoo Creep Resistance:Creep yog qhov qeeb, mus tas li deformation ntawm cov khoom nyob rau hauv qhov kev ntxhov siab tas li ntawm qhov kub thiab txias. Molybdenum muaj txiaj ntsig zoo hauv kev txhim kho cov hlau tsis kam mus rau creep, uas yog qhov tseem ceeb rau cov raj boiler uas ua haujlwm hauv siab.
