Dab tsi yog astm a500 qib ib square raj yield zog
ASTM A500 GrA yog ib qho tseem ceeb steel qauv tsim los ntawm American Society for Testing and Materials (ASTM), tshwj xeeb tshaj yog rau txias-tsim thiab kub- ua seamless thiab welded square thiab rectangular raj. Cov qauv no tau siv dav hauv ntau qhov chaw xws li kev tsim kho, kev tsim khoom siv tshuab, thiab txuas hniav, tshwj xeeb tshaj yog nyob rau hauv cov khoom thauj -cov kabmob, qhov chaw square tubes nyiam vim lawv cov khoom siv zoo tshaj plaws.
Chemical Composition (ASTM A500 Qib A)
| Element | Cov ntsiab lus ntau (%) |
|---|---|
| C (Carbon) | Tsawg dua lossis sib npaug li 0.26 |
| Manganese (Mn) | Tsawg dua lossis sib npaug li 1.35 |
| P (phosphorus) | Tsawg dua lossis sib npaug li 0.035 |
| S (Sulfur) | Tsawg dua lossis sib npaug li 0.035 |
| Cu (kwv yees) | Ntau tshaj los yog sib npaug rau 0.2 (thaum teev raws li tooj liab hlau) |
Mechanical Properties ntawm ASTM A500 Qib A
| Khoom | Tus nqi Range (Tswj) |
|---|---|
| Tensile zog | 400-550 MPa |
| Yield zog | Ntau dua lossis sib npaug li 250 MPa |
| Elongation Tom qab Fracture | >20% |
| Impact Toughness | Nyob rau hauv chav tsev kub rau 0℃F |
| Hardness | Brinell hardness tus nqi 137-155 |
A500 GRA yog dav siv hauv:
- Cov Khoom Siv Hauv Tsev: Raws li kev thauj khoom- cov kabmob xws li kab thiab kab teeb hauv cov qauv hlau;
- Machinery thiab Equipment: Kev tsim cov khoom siv thav duab, cov khoom siv conveyor, thiab cov khoom siv txhawb nqa;
- Choj Engineering: Siv los txhawb cov qauv rau cov neeg taug kev txuas hniav thiab cov choj me me;
- Warehouse Racking: Raws li cov khoom siv rau cov kab thiab kab teeb ntawm hnyav -cov haujlwm racking;
- Cov Khoom Siv Hauv Nroog: Cov kev thaiv tsheb, cov ncej teeb pom kev zoo, thiab cov ntawv tshaj tawm, thiab lwm yam.
