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 tool steel rectangle bar measures 0.0938 inches in thickness and 1.75 inches in width, made from O1 alloy. It is precision ground for excellent dimensional stability and is available in lengths up to 36 inches.

Yes, O1 tool steel offers excellent dimensional stability during heat treatment and experiences significantly less distortion compared to other tool steels like A-2 or D-2, making it ideal for rolls, punches, shear knives, and gauges.

Custom cutting is not available from the warehouse for this product, but a material test report (MTR) is available to ensure quality and compliance.

The O1 alloy has a high machinability rating of 95 and an ultimate tensile strength of 105 ksi, making it a strong and workable choice for general-purpose tooling.

The product is in stock and available in two length options: 18 inches and 36 inches, with shipping weights of 0.84 lb and 1.68 lb respectively, ensuring prompt delivery.
