Dab tsi yogSA656 Qib 80 steel?
SA656 Qib 80yog asiab-lub zog qis- alloy (HSLA) steel phajnrog aTsawg tshaj tawm lub zog ntawm 80 ksi (≈ 550 MPa).
Nws yog tsim rau cov ntawv thov uas xav tauTshwj xeeb lub zog, toughness, thiab weldability, haum rau cov khoom siv hnyav thiab cov khoom siv uas muaj kev ntxhov siab.
1. Chemical Composition (Qhov zoo tshaj plaws tus nqi)
| Element | Cov ntsiab lus (wt.%) |
|---|---|
| Cov pa roj carbon (C) | Tsawg dua lossis sib npaug li 0.22 |
| Silicon (Si) | Tsawg dua lossis sib npaug li 0.60 |
| Manganese (Mn) | Tsawg dua lossis sib npaug li 1.65 |
| Phosphorus (P) | Tsawg dua lossis sib npaug li 0.025 |
| Sulfur (S) | Tsawg dua lossis sib npaug li 0.035 |
| Vanadium (V) thiab / lossis Columbium (Nb) | Tsawg dua los yog sib npaug rau 0.08 (microalloying) |
| Nitrogen (N) | Tswj me me |
Kev sib xyaw yuav txawv me ntsis nyob ntawm lub phaj thickness thiab zeb.
2. Mechanical Properties
| Khoom | Yam tsawg kawg nkaus |
|---|---|
| Yield zog | Ntau dua lossis sib npaug rau 550 MPa (80 ksi) |
| Tensile zog | 620-700 MPa (90-100 ksi) |
| Elongation | 14-18% (nyob ntawm thickness) |
| Impact Toughness | Zoo; haum rau welded thiab hnyav -load qauv |
| Weldability | Zoo heev; tau tshaj cov txheej txheem vuam txheej txheem |
Puas yog SA656 Qib 80 sib npaug rau ASTM A572 Qib 80?
SA656 Qib 80 thiab ASTM A572 Qib 80yogzoo sib xws hauv lub zog thiab kev siv, tab sis lawv yogtsis nruj me ntsis zoo ib yamvim lawv tuaj ntawm txawv specifications nrog me ntsis txawv tshuaj thiab mechanical xav tau.
