|
8620 is a low alloy case hardening steel which is supplied to American standards SAE 8620 and AISI 8620. 8620 can be carburised, which will achieve a tough core with a hard wear resistant case. 8620 provides a combination of toughness and wear resistance. 8620 is supplied in either the as rolled or annealed condition for subsequent case hardening.

Mechanical properties are not stated in AISI 8620 or SAE 8620 as standard. The mechanical properties information for AISI 8620 / SAE 8620 is provided below as a guida. A test piece of 19mm diameter AISI 8620 / SAE 8620 is blank carburised for at least one hour at a temperature of between 880-930°C and allowed to cool at room temperature. The test piece of AISI 8620 / SAE 8620 is then re treated to 820-840°C and quenched in oil.

Principal Design Features
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.
Machinability
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.
Heat Treatment
CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.
Welding
Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
Forging
Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
