O1/1.2510 Cold Work Tool Steel
Description
O1 steel, also known as 1.2510 or 100MnCrW4, is a high-carbon, oil-hardening cold work tool steel known for its excellent dimensional stability, high hardness, and good wear resistance after heat treatment. It offers good machinability in the annealed state and can achieve a fine, even structure through proper heat treatment, making it suitable for precision tools requiring sharp edges and minimal distortion. O1/1.2510 is commonly used for knives, punches, gauges, cutting tools, and molds where high surface hardness and durability are critical. It provides a good balance between toughness and abrasion resistance, making it a reliable choice for both industrial applications and fine toolmaking.
