UNS S32615 Seamless Yeeb Nkab

S32615 (tseem hu ua F63) yog siab -kev ua tau zoo austenitic stainless hlau. Nws qhov tshwj xeeb corrosion tsis kam, siab -kub tsis kam, thiab cov khoom siv kho tshuab zoo heev ua rau UNS S32615 seamless yeeb nkab ua cov khoom tseem ceeb hauv kev lag luam tshuaj lom neeg, roj av, thiab marine engineering industries. Nws yog qhov kev xaiv zoo tshaj plaws rau kev tsim cov hlab ntsha, cov tshuaj reactors, cov kav dej, thiab lwm yam khoom siv.

Chemical Composition ntawm UNS S32615 seamless yeeb nkab:

• High Silicon (4.8-6.0%):Qhov tseem ceeb txhim kho corrosion kuj nyob rau hauv concentrated sulfuric thiab nitric acid, tshwj xeeb tshaj yog nyob rau hauv cov khoom siv tshuaj.
• Chromium (16.5–19.5%) thiab Molybdenum (0.3–1.5%):Synergistically tsim ib tug tuab passive zaj duab xis, tiv thaiv chloride ion pitting thiab crevice corrosion, ua rau nws haum rau siv nyob rau hauv seawater ib puag ncig.
• Nickel (19-22%):Stabilizes lub austenite theem, txhim kho qis -kub toughness thiab siab - kub lub zog.
• Tooj liab (1.5-2.5%):Txhim kho corrosion kuj nyob rau hauv acidic media, tshwj xeeb tshaj yog nyob rau hauv sulfur - muaj roj av ib puag ncig.
• Cov pa roj carbon tsawg (tsawg dua lossis sib npaug li 0.07%):Txo qhov kev pheej hmoo ntawm intergranular corrosion thiab ua kom muaj kev ruaj ntseg vuam.

Mechanical Properties

• Tensile zog:620-830 MPa; Yield zog: Ntau dua lossis sib npaug ntawm 205 MPa;
• Elongation:Ntau dua lossis sib npaug li 40%; Hardness: HB Tsawg dua lossis sib npaug rau 187;
• High -Tsub Ua Haujlwm:Ua kom muaj zog thiab tawv ntawm 1000 degree, nrog rau kev nkag siab zoo heev, ua rau nws haum rau siab - cov khoom siv kub xws li boilers thiab kub exchangers.

Weldability

• Cov txheej txheem siv tau:Gas shielded vuam (TIG, MIG, thiab lwm yam);
• Kev kho mob:Preheat rau 150-200 degree; Tom qab- Kev kho cua sov: Kev laus ntawm 750-800℃kom txo tau qhov kev pheej hmoo ntawm kev sib tsoo ntawm qhov chaw vuam.

Kev kho cua sov

Cov txheej txheem kho cua sov muaj qhov cuam tshuam loj rau cov khoom ntawm UNS S32615 seamless yeeb nkab. Kev kho mob yog txoj kev kho cua sov tshaj plaws, feem ntau ua ntawm 1050 thiab 1150 degree, ua raws li kev ua kom txias sai kom khaws cov qauv austenitic. Qhov kev kho no tshem tawm cov teebmeem ntawm kev ua haujlwm hardening, kho cov khoom siv corrosion thiab ductility.
