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 0.25 inches in thickness and 6 inches in width, 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.

Yes, O1 tool steel offers significantly less distortion during heat treatment compared to other steels like A-2 or D-2, making it ideal for precision applications such as 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 no custom cut warehouse availability, so custom cutting options may be limited or unavailable.

The 18-inch length weighs approximately 7.65 pounds, while the 36-inch length weighs about 15.3 pounds. Both lengths are currently in stock and ready to ship.

Yes, material test reports (MTRs) are available for this product, providing assurance of its chemical and mechanical properties.
