ASTM B161 Nickel 201 Yeeb Nkab

ASTM B161 Nickel 201 Yeeb Nkabyog qhov qis- carbon version ntawm kev lag luam ntshiab nickel. Qhov kev hloov pauv ntawd - carbon poob los ntawm 0.15% max hauv Nickel 200 rau 0.02% max hauv Nickel 201 - yog vim li cas qib muaj. Tshaj 315 degree, carbon nyob rau hauv Nickel 200 precipitates ntawm grain ciam teb raws li graphite thiab embrits cov hlau. Nickel 201 nres qhov ntawd.

 

Yog tias koj cov kab tuav cov dej qab zib kub, cov ntsev ntsev, lossis siab -kub txo cov kua qaub, Nickel 201 feem ntau yog qhov pib. Nplooj ntawv no suav nrog yam koj xav tau los qhia thiab txheeb xyuas: chemistry, cov khoom siv kho tshuab thiab lub cev, thaj tsam corrosion, qhov ntau thiab tsawg, thiab cov tshev uas ua pov thawj tias koj tau txais N02201 tiag.

Lub Ciam Tebchaws Carbon: Vim li cas Nickel 201 Muaj

Nickel 200 thiab Nickel 201 yuav luag zoo tib yam hauv kev tiv thaiv corrosion, hluav taws xob conductivity, thiab kev coj tus cwj pwm. Qhov sib txawv tsuas muaj txiaj ntsig yog carbon.

Qib	UNS	C max	Hom C	Siv Saum 315 degree?
Nickel 200	N02200	0.15 %	0.06 %	Tsis muaj - graphitization txaus ntshai
Nickel 201	N02201	0.02 %	0.01 %	Yog - ruaj khov microstructure

Qhov 0.02% carbon txwv yog qhov tso cai rau Nickel 201 ua haujlwm ntev -lub sijhawm ntawm qhov kub txog li 540℃hauv caustic thiab txo cov kev pabcuam. Rau kev pabcuam hauv qab 315 degree, Nickel 200 thiab Nickel 201 yog hloov pauv tau. Tshaj li qhov kub thiab txias, Nickel 201 yog tib txoj kev nyab xeeb ntawm cov khoom lag luam ntshiab nickels.
