1CR21AL4 Malaking Diameter Iron Chromium Aluminum Alloy
Ang 1CR21AL4 large-diameter iron-chromium-aluminum alloy ay may chromium content mula 17.0% hanggang 21.0%. Sa isang high-chromium na kapaligiran, ang oxide film na nabuo sa ibabaw ng haluang metal ay hindi lamang ng katamtamang kapal ngunit nagtataglay din ng napakataas na resistivity. Ang pelikulang ito ay nagpapakita ng napakababang ion migration rate sa pinakamataas na tuluy-tuloy na operating temperature na 1100°C, na epektibong humahadlang sa karagdagang oxidative degradation ng metal substrate. Ang hamon sa pagpoproseso para sa mga materyales na may malalaking diameter ay nakasalalay sa panloob na diin sa panahon ng baluktot. Ang 1Cr21Al4 ay nagpapanatili ng isang elongation rate na higit sa 12%, na nagpapahintulot sa mga inhinyero na iproseso ang mga heavy-gauge na wire sa hugis-U, corrugated, o helical na malalaking diameter na coil nang walang madalas na intermediate annealing.
