M35 steel is high speed tool steel. After the heat treatment, its hardness, red hardness and wear resistance can be improved.
12L14 is a free cutting structural steel. And it is easy to be machined. More information about it as below.
1045 carbon steel has a tensile strength is 570-700 MPa and Brinell hardness ranging between 170 and 210.
8620 steel is alloy steel and has good strength and toughness properties. This alloy steel is flexible during hardening treatments, thus enabling improvement of case/core properties.
4340 steel has great machinability, heat treatment stability and impact toughness. It is a medium carbon, low alloy steel.
4140 steel is an alloy structural steel with high strength, hardenability, good toughness and small deformation during quenching.
T1 HSS tool steel is the most widely used tungsten type of high speed steel. Its properties are great, has good abrasion, toughness and hardness(can reach 62~66HRC).
M42 high-speed steel is a cobalt-molybdenum tools steel. The addition of 8% cobalt means that M42 has superior red-hardness when compared to M2 steel.
AISI M2 high-speed steel has largely replaced T1 in most applications due to its superior properties and advantageous pricing. It is a medium alloyed high speed steel which has good machinability.
According to the AISI classification system, chromium hot-work tool steels are designated as group H steels. This series of steel start H1 from H1 to H19.
The hardness of A2 steel after heat treatment is higher than SKD11 steel. Its hardness could reach 60-62HRC after tempering in high temperature(500-520 °C).
O1 steel is a cold work mold steel. It has good wear resistance, stable heat treatment performance. Small deformation after the process, but toughness and corrosion resistance is weak.
P20 steel is a great mold material for making plastic molds and die-casting low-melting metals. It has good machinability and mirror polishing properties. P20 steel also is called 1.2311 steel.
H13 is a hot work die steel, which is a steel formed by adding alloying elements to carbon steel. It can be used in aluminum alloy die-casting molds, hot extrusion dies, and forging press dies. H13 steel also is called 1.2344 steel.
D6 steel is characterized by high compressive strength, high wear resistance, and good hardening stability. D6 steel is used for forming tools, molds and etc. D6 steel also is called SKD2 Steel.
D2 is tool steel and its content of carbon is 1.5%, the chromium content is 11.5%. The hardness will up to 60HRC by heat treatment. It also can be called DIN 1.2379 steel. DIN 1.2379 steel has good wear resistance and toughness. But its corrosion resistance is not good.
D3 steel is a high-carbon, high-chromium, oil-hardening tool steel.
