Tool Steel Rectangle Bar O1 Oversize 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 tool steel rectangle bar measures 0.125 inches thick by 2 inches wide, with a maximum length of 36 inches. It is made from O1 oil-hardening tool steel, known for excellent dimensional stability during heat treatment and good machinability.

The product is available in standard lengths of 18 and 36 inches with no custom cut warehouse stock, so custom cutting options may be limited. However, the bar is offered in two length variants ready to ship.

O1 tool steel is commonly used for rolls, punches, shear knives, food processing knives, and gauges due to its good wear resistance and minimal distortion during heat treatment.

Yes, a Material Test Report (MTR) is available for this product, providing assurance of its chemical and mechanical properties.

The 18-inch length variant ships at approximately 1.28 pounds, and the 36-inch variant at about 2.55 pounds. Both lengths are currently in stock and available for immediate shipment.
