is in the general class of alloy, oil-hardening tool steel that is
characterized by good toughness. ASTM L6 tool steel is suitable for use
as tools, dies, and machine parts, which require a good combination of
hardness and toughness.
Due to its lower carbon content and
relatively high nickel content, L6 tool steel has slightly better
shock-resistance than more highly alloyed types and should be used where
some wear-resistance can be sacrificed for increased toughness.

4. Forging of L6 Tool Steel
Forge at 1079°C (1975 F) down to 871°C (1600 F). Do not forge below 843°C (1550 F).
5. AISI L6 Tool Steel Heat Treatment
Heat steel L6 at a rate not exceeding 204°C (400°F) per hour (222°C per
hour) to 621-677°C (1150-1250°F) and equalize. Soak for 30 minutes for
the first inch (25.4 mm) of thickness, plus 15 minutes for each
additional inch (25.4 mm).
Quench L6 tool steel in oil to 66-51°C (150-125°F).
L6 steels immediately after quenching. Hold at temperature for 1 hour
per inch (25.4 mm) of thickness when tempering at 204°C (400°F), 4 hours
minimum, then air cool to ambient temperature.
However, where increased toughness is desired, at a sacrifice of some hardness, higher tempering temperatures are often used.
AISI L6 steel does not become brittle, as many other die steels do, when tempered in the range of 232°C to 426°C (450 to 800°F).
minimize the possibility of cracking, the steel should be tempered
immediately after hardening and should be heated slowly to the desired
Annealing of steel L6 must be performed after hot working and before re-hardening.
to 760°C (1400°F) and hold one hour per inch of maximum thickness. Then
cool slowly with the furnace at a rate not exceeding 28°C per hour(50°F
per hour) to 538°C (1000°F). Continue cooling to ambient temperature in
the furnace or in air.
For improved machinability, hold at 760°C
(1400°F) for 1 hour per inch (25.4mm) of maximum thickness; 2 hours
minimum. Then cool slowly with the furnace cool from 677°C (1250°F) to
760°C (1400°F), hold for 8 hours, then air cool to ambient temperature.
Because of its air-hardening ability, steel L6 should not be normalized.
6. Machinability of Steel L6
of tool steel L6 is very good. It rates 90% of the machinability of the
W-group water hardening low alloy steels rated 100% as a baseline.
7. Applications of ASTM A681 L6 Tool Steel
L6 cold working tool steel is for general purpose tools and dies where
greater toughness is required, but with some sacrifice of
Typically used below applications:

What’s new in 2015?
1. Closed-caption made by myself! — not the automatic subtitle anymore.
2. Learning objectives added for each video.
3. Quiz questions added — including end-of assessment questions and preparatory, exploratory questions.
4. Mistakes fixed and cleaned up.
5. New examples/contents for selective videos.
My old videos and playlists will still be left on YouTube. Feel free to watch either one. Personally I think the revised videos are better mainly because of the subtitle.
Learning objectives of this video:
1. To introduce particle curvilinear motion, which is the study of particle motion along a curved path.
2. To analyze curvilinear motion using rectangular coordinate system.
The Musashi forge is identified for continually generating useful and elegant katana swords with an remarkable worth mixed with spectacular overall performance.
Our new Folded Elite series carries on to increase the bar by providing differentially hardened folded metal blades mixed with special fittings. Wholly handmade with shut supervision and consideration to detail, these swords are designed to be collection and dojo centre parts.
Both of those 1045 and 1060 high carbon metal are fastened alongside one another and folded eleven times resulting in 4096 levels. The metal is then formed into the blade geometry and clay tempered to produce differential hardness and a genuine hamon line. The temper procedure also creates an edge hardness of 58RC. Now in its last stage of output, the blade is hand honed for an impressively sharp edge, really polished, inspected and coated with protecting oil.
The hamon line detail is on the multi-metal layered blade. The hamon line distinguishes in between the more difficult edge metal and the additional versatile spine metal, marking in which the metallic variations its hardness. The levels of metal are designed noticeable along the hamon line, resulting in a wonderful and special layered wave hamon.
