SAE M2 Tool Steel Material Mechanical Eigenskippen
Hurdens, Rockwell C (tempered by 621 ° C, quenched by 1204 ° C): 62 HRC.
Hurdheid, Rockwell C (blust by 1204 ° C)): 65 HRC
Smeden fan M2 HSS Steel metaal materiaal
Earst, Pre-heating nei 650-750 ℃, dan ferwaarmje nei smeid temperatuer. Soak op 1204 ° C, soargje foar waarmte. Dan begjinne smeid, de smeid temperatuer net leech dan 950 ℃. Nei it smeden, koelje stadichoan.
Warmtebehanneling fan SAE M2 Steel
Earst, stadich ferwaarmje oant 871 ℃, dan stadich koelje oant 538 ℃ (1000 ℉) yn waarmtebehannelingofen. Dan koelje yn 'e loft. Nei annealing hurdens HBS: 255 Max.
M2 stiel hawwende tige hege hardenability en moat wurde ferhurde troch koeling yn stille loft. It brûken fan in sâlt bad of kontrolearre atmosfear oven is winsklik te minimalisearje decarburization, en as net beskikber, pack ferhurding yn bestege pitch coke wurdt suggerearre.
- Blokkearjen fan HSS M2 Steel materiaal
