L6 Tool Steel | 1.2714 | 55NiCrMoV7 | SKT4 - Durable Tool Steel
AISI L6 Tool Steel, classified under the L-type in ASTM A681 for special purpose tool steels, is an oil-hardening alloy tool steel known for its excellent toughness. It is ideal for applications requiring a combination of hardness and toughness, such as tools, dies, and machine parts.
Due to its lower carbon content and relatively high nickel content, L6 tool steel offers better shock resistance compared to more highly alloyed tool steels, making it suitable for applications where increased toughness is preferred over wear resistance.
Otai Steel provides AISI L6 tool steel in various shapes and sizes, tailored to meet specific customer requirements.
