Alloy 3312 AISI/SAE 3312 High alloy carburizing grade for those heavy-duty applications requiring high core strength, toughness and fatigue resistance over and above the widely used AISI 8620.
Alloy 3312 AISI/SAE 3312 Core strengths in the order of 170,000 psi (1172 N/mm2) are attainable. It is the preferred grade for carburized parts in severe operating conditions with excellent low-temperature properties.
Alloy 3312 AISI/SAE 3312 3312 may also be used in the heat treated, non-carburized condition for many applications requiring extra strength and toughness. It is normally supplied in the annealed condition and hardness HB 212 would be typical.
Alloy 3312 AISI/SAE 3312 Typical Applications:
Heavy-duty gears, pinions, spline shafts, piston pins, transmission components, rock drilling bit bodies, plastic molds, etc

Alloy 3312 AISI/SAE 3312 Typical Heat Treatment
Forging
− Commence 1215˚C max.
− Finish 925˚C Bury in Mica.
− Annealing
− 840˚C Furnace cool
− Normalizing
− 900˚C Air cool
− Hardened & Tempered (Uncarburized) - Heat to 815˚/ 840˚C and oil quench or Heat to 840˚/ 870˚C and air quench, then temper at 200˚/ 650˚C according to properties required.
− Case Hardening - single refining treatment. After carburizing at 900˚/ 925˚C, cool to RT. Reheat to 775˚/ 800˚C, oil quench and temper at 200˚C.
