9SiCr
Performance: Commonly used low alloy tool steel with high hardenability, hardenability and tempering stability. Suitable for graded quenching and austempering, heat treatment deformation is small.
Uses: Used to manufacture tools with complex shapes, small deformation, high wear resistance and low speed cutting, such as drill bits, thread tools, die, taps, reamer, crepe plate, thread rolling wheel, gear milling cutter, and machine die. Molds such as printing dies are also used to make cold rolls, correction rolls, and elongated parts.
Production varieties: hot rolled, forged, cold drawn, hot rolled steel, cold rolled steel wire, silver bright steel wire.
8MnSi
Performance: It is made up of silicon and manganese content based on carbon tool steel T8. The hardenability of the steel is improved by increasing the silicon and manganese contents.
Uses: Used in the manufacture of wood tools such as chisels, saw blades and other tools, as well as in saw blades, inserts and so on.
Production varieties: hot rolled, forged, cold drawn.
CrO6
Performance: Low-alloy measuring blade steel with a small amount of chromium, which can obtain higher hardness and wear resistance after heat treatment. Due to the high carbon content, it is easy to form reticulated carbides, which affects its performance. In particular, the tools with large cross-sections, especially the thin-blade large-section tools, are more brittle.
Uses: For the manufacture of low-load operation, but also requires sharp edge tools, such as surgical tools
Cr2
Performance: Chromium-containing tool steel is made by adding a certain amount of chromium to the carbon tool steel T10. Its chemical composition is similar to that of ball bearing steel GCrl5. Due to the inclusion of chromium, the hardenability, hardness and wear resistance of the steel are higher than that of the carbon tool steel T10, and the dimensional change during heat treatment quenching and tempering is not large.
Uses: Used in the manufacture of measuring tools, such as samples, gauges, block gauges, ring gauges, thread plug gauges, sample columns, card plates, sample sets, etc., can also be used to make cold work dies such as wire drawing dies and cold dies, and low speed, Cutting tools with small amount of machining and not very hard machining materials, such as turning tools, inserting knives, reamers, etc., and cam pins, eccentric wheels, cold rolls, etc.
Production varieties: hot rolled, forged, cold drawn, hot rolled steel, drawn steel wire.
9Cr2
Performance: Chromium-containing cutting edge steel, because it contains a certain amount of chromium, improves the hardenability of steel, even if quenched in oil, it can obtain higher hardness. After proper heat treatment, it has good wear resistance and carbonization. The distribution of matter is relatively uniform.
Uses: Used in the manufacture of cold molds, stamping punches and dies, stamping dies, ether carpentry tools, etc., also used in the manufacture of cold rolls and calender rolls.
Production varieties: hot-rolled, forged, cold-drawn, hot-rolled steel, cold-rolled steel wire can be supplied to small and medium-sized modules according to the requirements of the purchaser.
W
Performance: Measuring tool with 0.80%~1.20mm% (mass fraction), the hardness and wear resistance after quenching is higher than that of carbon steel tool steel, the heat sensitivity is lower than that of carbon tool steel, and the heat treatment deformation is also small. When water quenching, cracks are not easy to occur, and tempering stability is good. Because of its low hardenability, it is usually only used to manufacture tools with small cross-section. Generally, parts with a thickness of 10mm~15mm can obtain uniform high hardness, and its hardness is HRC64~66.
Uses: Used to manufacture tools with small cross-sections, such as small twist drills, as well as cones, dies and manual reamers with low cutting speed and low working temperature.
Production varieties: hot rolled, forged, cold drawn cold, drawn steel wire, silver bright steel wire.
