- John
At SteelPro Group, we are a trusted supplier of L2 tool steel, offering a variety of forms including plates, bars, and rods. With extensive experience in the steel industry, we provide tailored solutions to meet your specific needs, ensuring high-quality materials and reliable delivery.
What Is L2 Tool Steel?
L2 steel is an oil-hardening tool steel that comes in medium-carbon (0.45%-0.65%) and high-carbon (0.65%-1.10%) versions. It is recognized for its strength, abrasion resistance, and excellent hardenability, due to the inclusion of chromium and vanadium. L2 steel is commonly used for tools such as punches, dies, spindles, and cold-heading dies.
What is Equivalent to L2 Steel?
L2 tool steel has equivalent grades in various international standards, including:
- UNS T61202 (United States)
- JIS G4404 SKT3 (Japan)
- DIN 1.2210 (Germany)

L2 Tool Steel Heat Treatment
At SteelPRO, we offer L2 tool steel in both annealed and pre-hardened conditions, giving you flexibility based on your specific needs.
Preheating
Gradually heat the L2 tool steel to 649°C (1200°F) to prevent thermal shock during the subsequent heating stages.
Austenitizing
Raise the temperature of the steel to 857°C (1575°F) for austenitizing. Maintain this temperature for 5 to 15 minutes, depending on the thickness of the material, to ensure the steel achieves a uniform structure before quenching.
Quenching
After austenitizing, cool the steel in oil. Oil is selected because it provides a controlled cooling rate, reducing the risk of cracking while ensuring the desired hardness is achieved.
Tempering
Temper the steel at 204°C (400°F) for 1 hour. This step reduces brittleness by allowing some of the internal stresses from the quenching process to dissipate. The hardness after tempering will be approximately RC 53.
