Hom 347 yog austenitic stainless hlau stabilized los ntawm kev ntxiv columbium (ntxiv rau tantalum) los txo lossis tiv thaiv carbide nag lossis daus thaum vuam thiab hauv kev pabcuam ntawm 800/1650ºF (430/900ºC.) Cov columbium ntxiv kuj txhim kho cov khoom kub. Cov qib muaj kev ua haujlwm zoo rau corrosion thiab oxidation thiab zoo creep zog. Hom 347 yog qhov zoo rau kev siv ntawm qhov kub thiab txias qhov twg carbide nag lossis daus tshwm sim nyob rau hauv cov qib tsis-stabilized.

APPLICATIONS
Hom 347 yog siv rau lub dav hlau collector rings thiab pa manifolds, expansion pob qij txha thiab kub kub txheej txheem khoom siv.
FORGING
Hom 347 muaj qhov muaj txiaj ntsig zoo, tab sis nws qhov sib txawv ntawm carbon thiab alloy steels yuav tsum raug coj mus rau hauv tus account. Hom 347 muaj zog kub dua li carbon, alloy, txawm martensitic stainless hlau, li no ntau dua forging pressures los yog ntau rauj tshuab yuav tsum tau forge nws - thiab lwm yam austenitic stainless hlau. Qhov tseeb ob mus rau peb zaug ntau npaum li lub zog yuav tsum tau ua kom forge 300 series stainless hlau raws li qhov yuav tsum tau ua rau carbon thiab alloy steels.
Hom 347 yog forged ntawm 2300/1700ºF (1260/930ºC,) thiab cua txias, tab sis kom paub meej dua, qhov kub thiab txias sib txuam nrog forging tej yam kev mob yuav raug siv, raws li hauv qab no:
| Kev txo qis (ingot tawg, yob forging, kos duab, thaiv, thiab rov qab extrusion) | 2300 (1260) |
| Kev txo qis qis (tiav forging thiab chim siab) | 2200 (1200) |
| Kev txo qis me ntsis (npib, txwv tsis pub thiab xaus kev ntxhov siab) | 2050 (1120) |
Rau siab tshaj plaws corrosion kuj, qhov chaw yuav tsum tau dej quenched tom qab forging los yog tom qab annealed thiab dej quenched.
