HOT WORK TOOL STEEL L6

In L6 steel grade is in L-type for unique reason tool steels. AISI L6 tool steel is in the general class of alloy, oil-solidifying tool steel that is described by great durability. ASTM L6 tool steel is appropriate for use as dies, and machine parts, which require a good combination of hardness and toughness.

Because of its lower carbon content and generally high nickel content, L6 tool steel has marginally preferred shock-resistance over all the more exceedingly alloyed types and ought to be utilized where some wear-resistance can be sacrificed for increased toughness.
