Mechanical Properties ntawm S235J2 Steel Phaj
S235J2 daim hlau yog tsim los tiv taus siab - ib puag ncig kev ntxhov siab, ua rau lawv zoo tagnrho rau kev siv steel hlau. Nov yog cov ncauj lus kom ntxaws txog cov khoom siv kho tshuab:
| Khoom | Tus nqi |
|---|---|
| Upper Yield zog (ReH) | 235 MPa (min.) |
| Tensile zog (Rm) | 360-510 MPa |
| Elongation ntawm Fracture (A80) | 15% (min.) |
| Elongation ntawm Fracture (A5) | 16-24% (nyob ntawm thickness) |
Tshuaj muaj pes tsawg leeg ntawm S235J2 Steel Phaj
Cov tshuaj muaj pes tsawg leeg ntawm S235J2 yog qhov tseem ceeb rau nws lub zog thiab kev ua haujlwm hauv cov qauv siv. Nov yog cov ncauj lus kom ntxaws:
| Element | Max % |
|---|---|
| Cov pa roj carbon (C) | 0.17% |
| Silicon (Si) | – |
| Manganese (Mn) | 1.40% |
| Phosphorus (P) | 0.025% |
| Sulfur (S) | 0.025% |
| Copper (Cu) | 0.55% |
Vim li cas nws tseem ceeb:
Cov ntsiab lus tsis tshua muaj carbon zoo txhim kho weldability thiab txo brittleness.
Manganese (Mn) txhim kho qhov tawv thiab hnav tsis kam, uas yog ib qho tseem ceeb rau siab - ib puag ncig kev ntxhov siab.
