O1 Tool Steel Sheet, Precision Ground, Annealed, 7/8" Thickness, 7/8" Width, 18" Product Details O1 tool steel has better machinability than A2 tool steel, and must be hardened in oil Meets ASTM A681 specifications Ground with high precision to the specified shape and size Standard tolerance Item Description The O1 tool steel sheet has been precision ground and polished, meets American Society for Testing and Materials International ASTM A681 specifications, and has a standard tolerance. The O1 tool steel grade has better machinability than A2 tool steel. It must be hardened in oil, which can be done at relatively low temperatures for good dimensional stability. The sheet has been ground to achieve the precise shape and is an iron alloy with carbon and other elements that modify the steel to achieve specific properties. In general, steels with higher carbon content have greater strength, hardness, and wear resistance, while those with lower carbon content have more formability, weldability, and toughness. Carbon steels, which include most AISI-SAE grades in the 1000 range, are classified by their level of carbon content as low (below 0.3%), medium (0.3% to 0.6%) and high (0.6% and above). Alloy steels, which include AISI-SAE grades in the 1300 and 4000 ranges and above, incorporate elements such as chromium, molybdenum, and nickel to modify properties like machinability and corrosion resistance. Tool steels, which include most grades with a letter and number grade designation, have high carbide content for wear resistance, high hardness, and the ability to hold a cutting edge. Some tool steels are designed to resist deformation when used in elevated strength, used to indicate a materials overall strength, is the peak stress it can withstand before it breaks.
