Wb delve rau hauv cov ntsiab lus intricate encompassed nyob rau hauv ASTM B162.
Taw qhia rau ASTM B162:
ASTM B162 tau teeb tsa cov lus qhia nruj rau kev tsim khoom thiab kev tswj xyuas zoo ntawm nickel phaj, daim ntawv, thiab cov khoom siv sawb, kom ntseeg tau tias lawv tsim nyog rau kev siv dav hauv ntau hom kev lag luam. Cov qauv no suav nrog ntau yam nickel-based alloys, txhua qhov sib txawv los ntawm cov khoom sib xyaw tshwj xeeb thiab cov yam ntxwv ua haujlwm.
ASME SB 162 Qib:
ASTM B162 encompasses ib assortment ntawm nickel-based alloys, suav nrog tab sis tsis txwv rau:
1. Nickel 200 (UNS N02200, 2.4066, 2.4060) UA: Renowned rau nws qhov tshwj xeeb corrosion kuj nyob rau hauv kev txo cov cheeb tsam, Nickel 200 pom nws kim heev kev siv nyob rau hauv chemical processing thiab electronics industries.
2. Nickel 201(UNS N02201, 2.4061, 2.4068) UA: Kev nthuav tawm cov yam ntxwv zoo sib xws rau ASTM B162 Nickel 200 tab sis nrog cov ntsiab lus qis dua, Nickel 201 tau txais kev pom zoo rau nws cov ductility zoo dua thiab thermal conductivity, ua rau nws zoo tagnrho rau cov ntawv thov cryogenic thiab cov chaw ua haujlwm caustic.
Cov yam ntxwv ua haujlwm:
Nickel alloys tswj nyob rau hauv ASTM B162 yog revered rau lawv zoo kawg li txhua yam khoom thiab corrosion kuj, ua rau lawv indispensable nyob rau hauv xav tau kev lag luam chaw. Cov yam ntxwv tseem ceeb ntawm kev ua haujlwm muaj xws li:
- Corrosion Resistance: Nickel alloys pom zoo tiv thaiv corrosion, ua rau lawv tsim nyog rau cov ntawv thov raug rau cov tshuaj lom neeg hnyav.
- High Temperature Stability: Cov alloys khaws lawv cov khoom siv dag zog thiab kev ncaj ncees txawm tias nyob rau qhov kub siab, ua kom ntseeg tau kev ua tau zoo hauv kev siv kub.
- Kev Ua Tau Zoo Tshaj Plaws: Nickel daim hlau, nplooj ntawv, thiab strips muaj qhov tshwj xeeb ductility, ua kom yooj yim ntawm kev tsim thiab tsim cov txheej txheem.
Kev tsim khoom:
Kev tsim cov npib tsib xee daim hlau, nplooj ntawv, thiab strips raws li ASTM B162 entails kev ua raws li cov txheej txheem nruj heev. Cov txheej txheem no yuav suav nrog:
- Melting thiab Refining: Nickel alloys yog melted thiab refined kom ua tiav cov tshuaj lom neeg muaj pes tsawg leeg thiab purity qib.
- Kub Rolling: Cov hlau molten yog cam khwb cia rau hauv slabs thiab tom qab kub dov kom ua tiav qhov xav tau tuab thiab cov duab.
- Txias Rolling thiab Annealing: Txias dov imparts qhov tseeb qhov tseeb thiab nto tiav, ua raws li los ntawm annealing los txo cov kev ntxhov siab sab hauv thiab txhim kho cov khoom siv kho tshuab.
Quality Assurance and Testing:
Kev ntsuas kev nyab xeeb zoo tau teev tseg hauv ASTM B162 suav nrog cov txheej txheem kuaj xyuas kom ntseeg tau tias muaj kev ncaj ncees thiab kev ua tau zoo ntawm cov ntawv npib tsib xee, cov ntawv, thiab cov strips. Cov kev tswj xyuas kev ua tau zoo muaj xws li:
- Chemical Composition Analysis: Kev tshuaj xyuas nruj nruj yog ua los xyuas kom meej tias kev ua raws li cov ntsiab lus ntawm cov alloy.
- Mechanical Testing: Tensile, yield, and elongation tests assess the mechanical properties of the material.
- Surface Inspection: Kev soj ntsuam pom thiab qhov loj me kom paub meej qhov zoo thiab qhov tseeb.
Dimensions thiab Tolerances:
ASTM B162 qhia txog qhov ntsuas qhov ntev thiab kam rau ua rau cov paib npib tsib xee, cov ntawv txheeb, thiab cov strips kom ntseeg tau tias muaj kev sib luag thiab sib xws. Qhov loj me tuaj yeem suav nrog:
- Thickness: Qhia txog qhov tso cai thickness ntau rau daim hlau, ntawv, thiab strips.
- Dav thiab Length: Txhais qhov dav thiab qhov ntev ntawm qhov tso cai, ua kom ntseeg tau raws li cov neeg siv khoom xav tau.
