Based in Houston, Texas, George Metals is a reputable producer and supplier of high-quality metal products for a variety of industrial uses. George Metals is known for its dependability and quality, offering everything from custom metal solutions to precisely engineered bars and wires. The Tool and Die Steel O1 Bar, which is highly valued for its exceptional hardness, wear resistance, and machinability, is one of its top products. These bars, which are produced in accordance with strict quality standards, are perfect for die-making, machining, and tooling operations. George Metals offers dependable, high-performing products that satisfy precise client specifications along with dependable delivery and first-rate customer support.
Die steel and tools Carbon (0.90–1.00%), manganese (0.40%), chromium (1.00%), and trace elements like silicon, phosphorus, and sulfur make up the majority of O1 Bars, which are oil-hardening steels. Excellent edge retention, high hardness, and wear resistance are the outcomes of this chemical structure. The steel has a tensile strength of 700–1,100 MPa and a hardness of 55–62 HRC after heat treatment. O1 is a good choice for precision tooling because of its exceptional dimensional stability and machinability. O1 is a great material for long-lasting, high-accuracy applications because of its consistent toughness and resistance to cracking under stress.

When choosing O1 tool and die steel bars, consider factors like hardness, wear resistance, machinability, heat treatment requirements, intended application (e.g., cutting, stamping), and cost-effectiveness for long-term use.
O1 tool and die steel bars have moderate resistance to corrosion due to their carbon content and alloy composition. However, they are not stainless and can rust without proper maintenance, such as coating or regular oiling.
O1 Tool and Perish Steel bars are widely used in industries where edge retention and wear resistance are critical for the production of high-precision tools and components. The production of cutting tools, punches, dies, forming molds, jigs, and blades are examples of common uses. It is appropriate for stamping, shearing, and forming tools used in demanding environments due to its exceptional machinability. For knives and blades that need to be consistently sharp, O1 is also a great option. Because of its dependable performance under stress, it is widely used in the manufacturing, metalworking, automotive, and aerospace industries, especially for the production of intricate, small, and highly precise components.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
