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 made from O1 tool steel, measuring 1 inch in thickness and 8 inches in width, with a maximum length of 36 inches. It features excellent dimensional stability during heat treatment and contains key alloy elements such as 0.94% carbon and 0.5% chromium.

Yes, O1 tool steel is an oil-hardening, general-purpose tool steel known for experiencing significantly less distortion during heat treatment compared to other steels like A-2 or D-2, making it ideal for precision applications.

Custom cutting is not available from the warehouse for this product. However, a material test report (MTR) is available to verify the steel's properties and compliance.

This O1 tool steel bar is commonly used for manufacturing rolls, punches, shear knives, food processing knives, and gauges due to its good machinability and wear resistance.

The product is available in two lengths: 18 inches with a shipping weight of approximately 40.76 pounds, and 36 inches weighing about 81.51 pounds. Both lengths are currently in stock and ready for shipment.
