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).

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.

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

In 2010, U.S. nonferrous scrap recuperation consisted of:
Light weight aluminum Recycling
Reaching acknowledge the major kinds of scrap metal is an important action in ending up being a successful scrap metal supplier.
With a recovery of 4.6 million statistics lots every year in the U.S, a lot more aluminum is reused than other nonferrous steels. Light weight aluminum is light and also generally very easy to bend. It will certainly not offer off sparks on a grinding wheel, and is nonmagnetic, unlike similarly colored steels such as steel. Although light weight aluminum is available in different grades, it is difficult to determine between them.

Just like any type of metal, much less contamination enhances the value, such as taking apart devices to separate different kinds of steel, or getting rid of various other contaminants such as covering with concrete or other material. Webbing and screws ought to be eliminated from grass chairs. Search for aluminum scrap in real estate and also demolition tasks, consisting of windows and door frameworks, gutters, siding, and also cable. In car shops, aluminum can be located in transmission cases and pistons.
Copper is the third most commonly recycled nonferrous metal. As a matter of fact, over 80% of copper ever before produced still exists. It is easy to determine due to the fact that of its distinct colour, and also that it is nonmagnetic. When placed against a grinding wheel, copper will not stimulate.
Stainless Steel Recycling
Stainless-steel is the 2nd most commonly recycled nonferrous metal. It incorporates steel alloys that includes a minimum percentage of chromium. An additional steel generally utilized as an alloy in stainless-steel is nickel. Unlike various other nonferrous metals, stainless steel could be magnetic, depending after nickel content. Much more nickel minimizes the magnetic homes of the stainless-steel. Stainless steel will spark in reaction to a grinding wheel.
Brass is an alloy of copper and zinc, along with tiny quantities of other metals including manganese, tin, iron or aluminum. The shade variety of brass includes red, yellow, gold and silver. In regards to magnetic destination, it could reveal from nonmagnetic to slightly magnetic. On the grinding wheel it will certainly vary in between no triggering to brief red sparks.

This video is about a tool I made to mark stock for punching and/or drifting holes from two sides.
The dies are made from H13 tool steel. The bottom die punches a slot that you can line up on the top side to punch a point. You can mark steel hot or cold.
