Tool Steel Rectangle 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.

This product is a precision ground rectangle bar with a thickness of 0.5 inches and a width of 10 inches. It is available in lengths of 18 and 36 inches.

Custom cutting is not available from the warehouse for this product, so it is sold in the specified lengths of 18 or 36 inches only.

O1 tool steel is an oil-hardening, general-purpose tool steel commonly used for rolls, punches, shear knives, food processing knives, and gauges due to its excellent dimensional stability during heat treatment.

O1 offers decent strength with an ultimate tensile strength of 105 ksi and excellent machinability rated at 95, making it easier to machine than some other tool steels.

Yes, a material test report (MTR) is available for this product to verify its chemical and mechanical properties.
