It is best to use alloy tool steel containing manganese. There is also an excellent tool material in the world, which I made myself. 1CR 13NI9TI (the letter behind it is changed to lowercase) is an aviation material, which is generally used for the girder of aircraft. But it's hard to deal with. It needs grinding.
Features and uses of carbon tool steel: carbon tool steel is short for carbon steel, and is widely used in tool steel because of its good cold and hot workability, good wear resistance and low price.
1.T7 steel is hypoeutectoid steel. After quenching and tempering, it has high strength and toughness and a certain hardness, but the thermal hardness is low, the hardenability is poor and the quenching deformation is large. It is often used to make tools that can withstand vibration and impact and require high toughness but low cutting performance, such as small pneumatic tools such as chisels and punches, woodworking saws and chisels, simple bakelite molds, forging molds, scissors, hammers and sickles.
2.T8 steel is * * * precipitation steel, which has high hardness and good wear resistance after quenching and tempering, but low hardness, poor hardenability, easy overheating when heating, large deformation and low plastic strength. It is often used for tools that need high hardness and wear resistance, such as simple dies and punches, tools for cutting soft metals, milling cutters and shafts for carpentry, chisels, chisels, circular saws, pliers assembly tools, vise jaws, etc.
3. The properties of 3.T8mn steel are similar to T8, but the hardenability is better and the hardened layer is deeper after adding manganese. The purpose is the same as T88, but tools with larger cross section can be made.
4. The performance of 4.T9 steel is the same as that of T8 steel, but due to its high carbon content, high hardness and wear resistance, low toughness. It is often used as tools with high hardness and toughness, but not subject to severe vibration, such as center chisel, die, punch, woodworking cutting tool, feeder blade, rock chisel, etc.
5.T 10 steel, which is too precipitated, is not easy to overheat when quenching and heating, and still maintains fine grains. The toughness is acceptable, the strength and wear resistance are higher than T7-T9, but the hardness is low, the hardenability is still not high, and the quenching deformation is large. This kind of steel has a wide range of uses, and is suitable for manufacturing tools with poor cutting conditions, high wear resistance, certain toughness and sharp cutting edges, such as turning tools, planers, drill bits, taps, reaming tools, dies, hand saws of milling cutters, small-inch cold trimming dies and punching dies, low-precision and simple-shaped measuring tools (such as splints), and can also be used as wear-resistant parts without big impact.
6.T 1 1 steel is hyperprecipitated steel, with carbon content between T10 and T12, and has good comprehensive mechanical properties (such as strength, hardness, wear resistance, toughness, etc.). ). The application is basically the same as that of T 10 steel, but not as extensive as that of T 10 steel.
7.T 12 steel has high carbon content and good wear resistance, but it is brittle. Used as various shock-resistant tools and wear-resistant parts, such as turning tools, milling cutters, taps, wrenches, files, scrapers, small cold trimming dies, punching dies, etc.
8.T 13 is the steel with the highest carbon content, the highest wear resistance and the most brittle. The application is basically the same as that of T 12 steel, and it can also be used as a mechanical part that is not impacted and requires extremely high wear resistance.
