Q195 Steel yog dab tsi?
q195a uaSuav tus qauv qis- carbon steel qibtxhais nyob rau hauv GB / T 700, dav siv nyob rau hauv ntau yam kev lag luam. Qhov kev xaiv ua raws li Suav naming convention: tsab ntawv Q stands rau yield zog (qu fu dian) thiab tus naj npawb 195 yog qhov tsawg kawg nkaus yield zog nyob rau hauv MPa. Vim nws cov ntsiab lus carbon tsawg, Q195 muaj qhov zoo ductility thiab formability, ua rau nws yog ib qho khoom siv nrov rau kev tsim cov khoom siv, cov kav dej thiab cov khoom siv hlau.
Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm Q195 yog nruj tswj xyuas kom cov hlau mos, ductile thiab yooj yim rau kev tsim. Cov pa roj carbon yog txwv rau qhov nqaim qis, nrog cov ntsiab lus ntawm manganese thiab silicon thiab tsis muaj impurity txwv ntawm phosphorus thiab sulfur.
| Element | Txwv |
|---|---|
| Cov pa roj carbon (C) | 0.06 - 0.12% |
| Manganese (Mn) | 0.50% max |
| Silicon (Si) | 0.30% max |
| Phosphorus (P) | 0.035% max |
| Sulfur (S) | 0.040% max |
Mechanical Properties
Q195 muaj lub zog tawm los ntawm 195 MPa thiab lub zog tensile xws li 315 txog 430 MPa. Qhov elongation yog kwv yees li 33% rau cov qauv kuaj nrog txoj kab uas hla ntawm 40 mm lossis tsawg dua, uas qhia txog qib qhov zoo ductility. Cov khoom siv ceev yog 7.85 g / cm³, tib yam li rau feem ntau cov pa roj carbon steels.
| Khoom | Tus nqi |
|---|---|
| Yield zog, min | 195 MPa ua |
| Tensile zog | 315 - 430 MPa |
| Elongation (d Tsawg dua lossis sib npaug li 40 mm) | Txog 33% |
| Qhov ntom | 7.85 g / cm³ |

Cov khoom sib npaug no muaj qhov sib xws tsawg tsawg -carbon chemistry thiab qib sib piv lub zog, yog li kev hloov pauv feem ntau ua tau tom qab kuaj xyuas cov khoom tsim nyog thiab cov kev xeem ntawm daim ntawv thov.
Daim ntawv thov thiab cov yam ntxwv ua haujlwm
Q195 yog ntau yam tsawg-nqi steel siv nyob rau hauv cov qauv teeb, laj kab, hlau mesh, ntsia hlau, fasteners, nyias- cov hlab ntsa thiab cov seem tsim. Nws qhov txias txias zoo heev - ua tus cwj pwm haum rau kev khoov, kos duab thiab stamping kev ua haujlwm. Vim nws tsis tshua muaj zog, nws tsis yog tsim rau cov neeg ua haujlwm hnyav hnyav; Q235 lossis qib siab dua yuav tsum raug xaiv qhov twg yuav tsum muaj peev xwm thauj khoom ntau dua.
