SUS431 Stainless hlau tshuaj muaj pes tsawg leeg
Element | Kev sib xyaw (wt%) | Lub luag haujlwm / cuam tshuam |
|---|---|---|
Cov pa roj carbon (C) | 0.20-0.30% | Cov ntsiab lus carbon siab nce hardness thiab hnav tsis kam tom qab kev kho cua sov. |
Manganese (Mn) | 0.60-1.00% | Txhim kho lub zog thiab toughness, tshwj xeeb tshaj yog nyob rau hauv qis kub. |
Chromium (Cr) | 16.0 – 18.0% | Muab kev tiv thaiv corrosion thiab oxidation, txhim kho durability. |
Nickel (Ni) | ≤ 0.60% | Txhim kho formability thiab ductility, txawm tias qis dua hauv qib austenitic. |
Phosphorus (P) | ≤ 0.04% | Txo cov kab mob sulfur thiab txhim kho machinability. |
SUS431 Stainless hlau lub cev muaj zog
Khoom | Tus nqi | Sau ntawv |
|---|---|---|
Qhov ntom | 7.80 g / cm³ | Me ntsis denser dua li lwm yam martensitic stainless hlau, ua kom ruaj khov. |
Melting Point | 1,400-1,530 ° C | Haum rau ob qho tib si txias thiab kub ua haujlwm, zoo tagnrho rau kev siv siab - kub. |
Thermal conductivity | 26.3 W/m·K | Nruab nrab cua sov dissipation, haum rau siab - cov ntawv siv cua sov. |
Hluav taws xob Resistivity | 7.4 × 10⁻⁷ Ω·m | Tsawg hluav taws xob conductivity, zoo tagnrho rau cov uas tsis yog - hluav taws xob daim ntawv thov. |
SUS431 Stainless Hlau Mechanical Properties
Khoom | Tus nqi | Kev xeem Standard/Condition |
|---|---|---|
Tensile zog | 700 MPa | ASTM A240 / A240M tus qauv |
Yield zog | 500 MPa | Haum rau siab -cov ntawv siv zog |
Elongation (50 hli ntsuas) | 15% | Nruab nrab ductility rau shaping thiab sib sau. |
Brinell Hardness | 450-500 HB | Ua tiav tom qab kev kho cua sov, muab kev hnav zoo heev. |
Machinability Rating | 55% (vs . 1212 steel ntawm 100%) | Haum rau machining, txawm tias nws yuav tsum tau qeeb ceev los tswj hardness. |
