Ultrasonic test: according to SEP 1921-84
Machinability:
Machinability of GCr15 alloy is good by conventional methods. A spherodizing anneal at 1200 F before machining will improve the overall machinability of the alloy.
Forming
GCr15 may be formed by all conventional methods, including cold forging or stamping and hot or cold upset forming.
Heat Treatment
Heat treatment consists of heating to 1500 F followed by an oil quench for through hardening of the alloy. A normalizing heat treatment at 1600 F and slow cooling, to relieve machining stress, may be employed prior to the 1500 F and quench treatment.
Forging
The alloy may be supplied as forgings and also may be subsequently forged at 2200 F down to 1700 F
Hot Working
Hot working, such as upsetting, may be done in the range of 400 to 1000 F.
Cold Working
The alloy has good ductility and may be cold worked in the annealed or normalized conditions by conventional methods.
Annealing
Anneal at 1600 F and slow cool to relieve machining or cold working strains.
Tempering
Temper at 400 F.
Hardening
The alloy hardens from cold working or by heating and quenching - see "Heat Treatment". It also may be carburized at 1675 F and quenched after sufficient time for carburization. A second heating to 1450 F and second quench from that temperature should be used.
Certificate of Quality: issued in English, in addition the normal terms, production process, the mechanical property (yield strength, tensile strength, elongation and hardness), forged ratio, UT test result, Grain size, heat treatment methods and the sample of is shown on the Certificate of Quality.
Marking: Heat No. will be cold stamped and Steel grade, diameter (mm), length (mm), and the manufacturer LOGO and weight (kg) is painted.
