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.

The O1 tool steel rectangle bar is commonly used in rolls, punches, shear knives, food processing knives, and gauges due to its excellent dimensional stability during heat treatment and good general-purpose attributes.

This product is available in standard lengths up to 36 inches, with options for 18-inch and 36-inch cuts. Custom cut options are not available from the warehouse.

O1 tool steel has a high machinability rating of 95, making it easier to machine compared to harder tool steels like A-2 or D-2, while still offering good strength and wear resistance.

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

The rectangle bar is in stock and ships with weights of approximately 4.79 lbs for the 18-inch length and 9.57 lbs for the 36-inch length, ensuring prompt delivery.
