Steel Grades We Machine
1045 Steel
Medium carbon steel used for shafts, bolts and gears. Yield tensile strength 450 MPa and Brinell hardness 170.
1215 Steel
A free machining grade chosen where cycle time and surface finish matter more than strength.
4130 Steel
Chromium molybdenum alloy steel used where strength to weight matters.
4140 Steel
A widely used alloy steel for shafts and highly stressed components, responsive to heat treatment.
4340 Steel
A nickel chromium molybdenum steel for high strength, high toughness applications.
A514 Steel
A quenched and tempered high strength structural plate steel.
Steel CNC Machining FAQ
Can you heat treat steel parts after machining?
Carburizing is one of our listed finishing processes, and hardness is verified with a micro-hardness tester in our inspection room.
What surface finish can grinding reach on steel?
As fine as Ra 0.2 micrometres, with dimensional tolerances of +/-0.002 inches.
Do you offer nickel plating?
Yes. Nickel plating, powder coating, carburizing and bead blasting are the finishing options listed for our steel machining service.
Which grade for a shaft?
1045 is the common choice for general shafts. Where the shaft is highly stressed, 4140 or 4340 with heat treatment is the better route.
