Chemical composition % of the ladle analysis of grade 50CrV4 and Standards

50CrV4 is a tough oil quenching spring steel.  When heat treated 50CrV4 offers good wear resistance. 50CrV4 is characterised by the addition of vanadium to the specification which differs 50CrV4 from standard spring steel specifications.

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 HM 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 F ( 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, H, H, H, H- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION HM- Soak solution treated material at F (760 C) for 2 hours, air cool, then re-heat to 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 F ( C) prior to forging. Do not work below F ( C). Post-work solution treatment is required prior to final hardening.

1. The study examines the effects of plasma nitriding on improving the fatigue resistance of 50CrV4 low-alloy steel. 2. Plasma nitriding creates a diffusion layer in the steel by introducing nitrogen into the surface that forms nitride compounds and increases hardness. 3. Testing found that plasma nitriding improved the fatigue limit of the steel at 1x107 cycles by 44%, due to the stabilized gradient of properties in the treated layer.
