Tool Steel Square Bar O1 offers excellent dimensional stability during heat treatment, and otherwise decent attributes. O1 is an oil-hardening, general purpose tool steel. While not as strong or wear resistant as A-2 or D-2, it experiences significantly less distortion during the heat treating process. It is typically used in rolls, punches, shear knives, food processing knives, and gauges.

Chemistry Information : O1 Tool Steel
The 1/4" Tool Steel Square Bar O1 is commonly used for rolls, punches, shear knives, food processing knives, and gauges due to its excellent dimensional stability during heat treatment and general purpose tool steel properties.
This product is available in standard lengths of 18 and 36 inches, but it does not support custom cut options from the warehouse.
O1 tool steel offers a high machinability rating of 95, making it easier to machine compared to stronger tool steels like A-2 or D-2, which typically have lower machinability.
Yes, a Material Test Report (MTR) is available for the 1/4" Tool Steel Square Bar O1, providing assurance of its chemical and mechanical properties.
The bar weighs approximately 0.21 lb per unit, has an ultimate tensile strength of 105 ksi, a yield tensile strength of 58 ksi, and a shear strength of 58 ksi, offering a good balance of strength and dimensional stability.
