Txhua Yam Koj Yuav Tsum Paub Txog Astm B168 Standard

Taw qhia rau ASTM B168:

ASTM B168yog ib qho kev qhia tshwj xeeb uas tsim los ntawm American Society for Testing and Materials (ASTM) uas qhia txog cov kev cai rau cov nickel-chromium-hlau alloys (UNS N06600, N06601, N06603, N06690, N06693, N06025, N06045, thiab N06696), nickel-chromium-cobalt-molybdenum alloys (UNS N06617), nickel-hlau-chromium-tungsten alloys (UNS N06674), thiab nickel-chromium-molybdenum-tooj liab alloy (UNS N06235) phaj, ntawv, thiab sawb.

Xws li Qib thiab Tshuaj Chemical Composition:

ASTM B168 encompasses ntau qib ntawm nickel alloys, txhua tus nrog nws cov tshuaj muaj pes tsawg leeg. Nov yog qee qhov sib xws:
1. UNS N06600 (Inconel 600, 2.4816): Feem ntau tsim los ntawm nickel, chromium, thiab hlau, nrog ntxiv ntawm manganese, tooj liab, thiab carbon.
2. UNS N06601 (Inconel 601, 2.4851): Feem ntau muaj npib tsib xee, chromium, thiab txhuas, nrog rau cov hlau tswj.
3. UNS N06603 (ib.Tom ntej: Inconel 603XL): Ua los ntawm npib tsib xee, chromium, thiab hlau, nrog ntxiv ntawm txhuas thiab titanium.

5. UNS N06674 (ib.Ib 617): Muaj cov nickel, chromium, hlau, thiab tungsten, nrog cov kab ntawm manganese, silicon, thiab carbon.
6. UNS N06235 (ib.Haynes 625): Nickel-based alloy nrog cov nyiaj tseem ceeb ntawm chromium, molybdenum, thiab niobium, nrog rau me me ntxiv ntawm hlau thiab cobalt.

Mechanical Properties:

Cov khoom siv kho tshuab ntawm ASTM B168 alloys sib txawv nyob ntawm qib, tuab, thiab kev kho cua sov. Tej yam khoom muaj xws li tensile zog, yield zog, elongation, thiab hardness.

ASME SB 168 Qhov Loj thiab Kev Pom Zoo rau Daim Hlau thiab Coils:

Phaj: Thickness range ntawm 0.1875 ntiv tes mus rau 4.000 ntiv tes, dav txog 48 ntiv tes, thiab ntev txog 144 ntiv tes.
Coils: Thickness range ntawm {{0}}.002 ntiv mus rau 0.187 ntiv tes, dav txog 48 ntiv tes, thiab coil hnyav txog li 10,000 phaus.

Tolerances rau qhov ntev xws li thickness, dav, thiab ntev yog teev nyob rau hauv tus qauv los xyuas kom meej cov khoom uniformity thiab zoo.
