Principal Design Features
|
|
This is one of the Special Purpose, low alloy tool steel grades, similar to the W group of low alloy tool steels. L6 contains nickel, chromium and molybdenum for a good combination of toughness and hardenability.
|
|
|
Applications
|
|
Typically used in machine tool applications such as bearings, springs, rollers or chuck parts.
|
|
|
Machinability
|
|
Machinability of L6 is very good. It rates 90% of the machinability of the W group water hardening low alloy steels rated 100% as a baseline.
|
|
|
Forming
|
|
L6 may be readily formed by conventional means.
|
|
|
Welding
|
|
This alloy is weldable. Consult the supplier for proper procedures.
|
|
|
Heat Treatment
|
|
Heat slowly to 1500 F and hold at temperature for 10 to 30 minutes. Oil or water quench.
|
|
|
Forging
|
|
Forge at 1975 F down to 1600 F. Do Not forge below 1550 F.
|
|
|
Hot Working
|
|
See "Forging".
|
|
|
Cold Working
|
|
L6 may be cold worked by conventional means as with the low alloy steels.
|
|
|
Annealing
|
|
Anneal at 1450 F and slow cool at a maximum of 40 F per hour.
|
|
|
Aging
|
|
Not applicable to this alloy.
|
|
|
Tempering
|
|
Tempering is done in the range of 350 F to 1000 F for Rockwell C 62 to 45 range.
|
|
|
Hardening
|
|
See "Heat Treatment" and "Tempering".
