Ki pi bon Superalloy la?

Ki pi bon superalloy la?

 

Superalloys are heat-resistant alloys of nickel, iron-nickel, and cobalt that can be used at high temperatures, typically >70% nan tanperati k ap fonn yo. Yo ka itilize nan tanperati ki depase 1050 degre, jiska 1200 degre. Rezistans tanperati sa a fè li yon ranplasman apwopriye pou carbure tengstèn nan aplikasyon pou pick-up.

The most widely used type of superalloy is nickel-based, which contains high concentrations of chromium, iron, titanium, cobalt and other alloying elements. Like other groups of metallic materials, the properties of superalloys can be tuned through various heat treatments and/or annealing and quenching. High-temperature alloys have the highest maximum service temperatures and the highest hardness values compared to other material groups. The strength of superalloys makes them an excellent alternative to carbide in high bonding force applications (>1kg).

Inconel alyaj 718 gen dite maksimòm ki pi wo a, men li gen yon tanperati sèvis maksimòm ki pi ba pase lòt alyaj wo-tanperati tankou Incoloy 925, Nitronic 60 ak Stellite 31. Superalloy ki pi lajman itilize se alyaj 718, ki konte pou plis pase 50% nan superalliaj yo itilize jodi a. Alloy 718 se yon chwa popilè pou zouti yo itilize nan aplikasyon pou tache chip.

Lòt klas alyaj tanperati ki wo yo itilize nan seri pwodwi nou an se Nitronic ak Stellite. Nitronic 60 ofri pi bon konbinezon de dite segondè (jiska HRC 46) ak tanperati sèvis maksimòm. (980 degre). Nitonic 60 se li te ye pou ekselan pwopriyete anti-mete li yo.

Stellite® superalliaj yo se alyaj cobalt ak chromium, ansanm ak lòt eleman ki amelyore pwopriyete alyaj pou aplikasyon espesifik. Kontni kabòn nan alyaj Stellite gen yon gwo enfliyans sou pwopriyete li yo. Pa egzanp, Stellite 6 gen pi wo kontni kabòn pase Stellite 31 (1.2% kont 0.5%). Konpare ak Stellite 31, Stellite 6 gen yon pi wo dite men yon tanperati sèvis maksimòm pi ba. Stellite 31 se yon altènatif ekselan nan carbure lè yo itilize kòm materyèl debaz pou distribye bouch ak zouti Stamping nan sistèm adezif nou yo.
