Applications of ASTM A681 O2 Tool Steel
I. General Tool Manufacturing
O2 tool steel is widely used in the production of various general-purpose tools due to its high hardness and wear resistance, such as bench tools, measuring tools, and cutting tools. These tools are subjected to friction and wear during long-term use, and the excellent properties of O2 tool steel ensure their durability and precision.
II. High-Stress Plastic Molds
O2 tool steel also excels in the manufacturing of high-stress plastic molds. Plastic molds need to withstand high temperatures and pressures during the injection molding process, and their surfaces must remain smooth to prevent plastic adhesion. The high hardness and wear resistance of O2 tool steel enable it to resist wear and corrosion from plastics, while its good thermal stability ensures dimensional stability of the molds at high temperatures.
III. Mold Inserts
For mold inserts requiring high hardness and abrasive stress, O2 tool steel is an ideal choice. Mold inserts play a crucial role in molds, and their performance directly affects the overall performance and lifespan of the molds. The high hardness and wear resistance of O2 tool steel ensure that the inserts maintain stable performance during long-term use, reducing replacement frequency and lowering production costs.
IV. Metal Sheet Processing Tools
O2 tool steel is also used to manufacture blanking and stamping tools for cutting all types of metal sheets up to a thickness of 6mm. These tools are subjected to tremendous impact and friction forces during the metal sheet processing, and the excellent properties of O2 tool steel ensure their durability and machining accuracy.
V. Cold Forming Tools
O2 tool steel also plays an important role in cold forming processes. Cold forming is a machining method that induces plastic deformation in metal materials at room temperature through pressure to obtain the desired shape and size. The high hardness and wear resistance of O2 tool steel enable it to resist friction and wear during the cold forming process, ensuring smooth progress of the machining.
