In ASTM A681 standard, L6 steel grade is in L-type for special purpose tool steels. AISI L6 tool steel 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.
AISI L6 cold working tool steel is for general purpose tools and dies where greater toughness is required, but with some sacrifice of abrasion-resistance.

Heat treatment temperatures, rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities.
Preheat to 600-700°C. Soak thoroughly, then increase rapidly to the hardening temperature of 850-880°C. Air or oil quench. Tools should be tempered as soon as they become hand-warm.
Heat uniformly to the required temperature allowing a soaking time of two hours per 25mm of ruling section. Withdraw from the furnace and allow to cool in air. A second tempering is highly recommended, the tool being allowed to cool to room temperature between tempers.
Forging ratio: 4:1 Minimum
Preheat slowly to 700°C then increase temperature more rapidly to 1050°C. Do not forge below 800°C. It is essential to cool slowly after forging, either in a furnace or in vermiculite.
When tools made from 1.2714 steel are heavily machined or ground, the relief of internal strains is advisable before hardening to minimize the possibility of distortion. Stress relieving of this grade should be done after rough machining. To stress relieve, heat the component carefully to 600-650°C, allow a good soaking period, about two hours per 25mm of section. Cool in the furnace to 500°C then freely in air. Tools may then be finish machined before hardening.
Soak thoroughly at 740-760°C before furnace cooling at a maximum rate of 10°C per hour down to 600°C followed by cooling in air.
Machinability 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.
