1.2210 is a widely recognized cold work tool steel that belongs to the German standard DIN 17350. It is known for its high wear resistance, good toughness, and excellent dimensional stability during heat treatment. Due to its reliable performance and broad applications, many countries have equivalent steel grades to DIN 1.2210, such as L2 from the American standard ASTM A681, 115CrV3 from International standard ISO 4957, and SKS43 from the Japanese standard JIS G4404.
1.2210 steel contains chromium, nickel, and molybdenum, which contribute to its hardness and toughness. The nickel content enhances its impact resistance, while the molybdenum improves hardenability and wear resistance.

AISI L2 Cold Work Tool Steel (DIN 115CrV3 1.2210, JIS SKS43) is a globally recognized cold work tool steel compliant with DIN 17350 and ASTM A681 standards. Engineered for demanding cold-forming and cutting applications, this grade stands out for its exceptional wear resistance, high toughness, and dimensional stability during heat treatment. DIN 115CrV3 1.2210 Steel contains chromium, vanadium, and trace alloys that enhance hardness and durability—making it a top choice for molds, tools, and precision components. With equivalents including ISO 115CrV3 and JIS SKS43, it offers consistent performance across international manufacturing workflows.
The high carbon (1.10-1.25% for DIN 115CrV3) and chromium (0.5-0.8%) content forms hard carbides, delivering superior wear resistance for repetitive cold-working operations.
During heat treatment, JIS SKS43 Tool Steel maintains tight tolerances—critical for precision molds and tools where dimensional accuracy directly impacts product quality.
Unlike brittle high-carbon steels, AISI L2 combines HRC 60+ hardness (after heat treatment) with good toughness—resisting chipping and cracking during high-impact cold forming.
It accommodates various manufacturing processes, including forging, machining, and heat treatment, with consistent performance across different supply forms.
