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 product is a 1 inch thick by 2.5 inch wide rectangle bar made from O1 tool steel. It is ground oversize for precision and available in lengths up to 36 inches. The alloy O1 is an oil-hardening, general-purpose tool steel known for excellent dimensional stability during heat treatment.

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

The bar is available in two standard lengths: 18 inches and 36 inches. However, the product data indicates that custom cut options are not available from the warehouse for this item.

The O1 tool steel has a high machinability rating of 95, which means it is relatively easy to machine, allowing for efficient shaping and finishing in various tooling applications.

Yes, an MTR is available for this product, providing detailed certification of its material properties and compliance.
