T 10 is the most common carbon tool steel with moderate toughness and low production cost. After heat treatment, the hardness can reach above 60HRC. However, this kind of steel has low hardenability and poor heat resistance (250℃), and it is not easy to overheat when quenching and heating, and still maintains fine grains. Toughness is acceptable, strength and wear resistance are higher than T7-T9, but hardness and hardenability are still low. Quenching deformation requires certain toughness and various tools with sharp edges, and can also be used as wear-resistant parts that do not bear great impact.

This kind of steel has a wide range of uses, and is suitable for manufacturing all kinds of cutting tools with poor cutting conditions, high wear resistance, certain toughness and sharp cutting edges, such as turning tools, planers, drill bits, taps, reaming tools, screw dies and hand saws of milling cutters, as well as cold heading dies, stamping dies, wire drawing dies, aluminum alloy cold extrusion dies, paper cutting dies, plastic forming dies and small-sized cold trimming dies.
