Hongxin - Model JIS SKD11 - High Carbon High Chromium Tool Steel for Cutting Tools
JIS SKD11 is a high carbon, high chromium, and high vanadium tool steel known for its high hardness, wear resistance, and toughness, which makes it ideal for various industrial applications that require high abrasion resistance and superior cutting performance. This steel is extensively used in the manufacture of cutting tools, molds, and dies, boasting an excellent combination of properties attributed to its specific chemical composition of 1.4-1.6% C, ≤ 0.60% Si, ≤ 0.60% Mn, 11-13% Cr, 0.7-1.2% Mo, and 0.2-0.5% V. JIS SKD11 is heat treatable and offers hardness levels in the range of 55-62 HRC. The steel shows minimal distortion upon correct hardening and possesses mild corrosion resistance due to its high chromium content. In terms of mechanical properties, JIS SKD11 exhibits significant tensile strength, yield strength, elongation capability, and impact resistance, with performance varying based on the heat treatment process employed. It's suitable for long-run tooling applications such as blanking or forming dies, punches, forming rolls, knives, slitters, shear blades, and scrap choppers.JIS SKD11 is a versatile tool steel that offers a combination of high hardness, wear resistance, and toughness, making it a popular choice for a wide range of industrial applications.

JIS SKD11 is a high carbon, high chromium, and high vanadium tool steel that is commonly used in the manufacturing of cutting tools, molds, and dies. Its high hardness, wear resistance, and toughness make it suitable for applications that require high levels of abrasion resistance and cutting performance. JIS SKD11 steel is an air hardening, high-carbon, high-chromium tool steel. It has high wear and abrasion resistant properties. It is heat treatable and will offer a hardness in the range 55-62 HRC, and is machinable in the annealed condition. JIS SKD11 steel shows little distortion on correct hardening. Cr12Mo1V1 steel’s high chromium content gives it mild corrosion resisting properties in the hardened condition.
If customer need better machinability, we recommend A2, because A2 has a chromium content of 5% and is more readily machinable.
- JIS SKD11 steel application
JIS SKD11 tool steels are used for long run tooling applications, where wear resistance is important, such as blanking or forming dies, punches, forming rolls, knives, slitters, shear blades, tools, scrap choppers, tyre shredders and so on.
- JIS SKD11 steel mechanical properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.
- JIS SKD11 steel heating treatment
JIS SKD11steels alloy should be preheated very slowly to 815℃ (1500°F) and then temperature can be increased to 1010oC (1850°F). They are then held at 1010oC (1850°F) for 20 to 45 minutes and air cooled (air quenched).
Annealing
Annealing of JIS SKD11 tool steels material should be done at 871 to 898°C (1600 to 1650°F) followed by slow furnace cooling at 4.4°C (40°F) per hour or less.after which cooling rate may be increased. Suitable precautions must be taken to prevent excessive carburization or decarburization.
Stress Relieving
When desirable to relieve the strains of machining, heat JIS SKD11 grade steel slowly to 1050°-1250°F, allow to equalize, and then cool in still air (Strain Relieving).
Preheat Prior To Hardening
Preheat slowly to 1350°-1450°F and hold at this temperature until grade steel JIS SKD11 material is uniformly heated.
Hardening
After thorough preheating, heat to 1800°-1850°F. Hold the work piece at the hardening temperature until it is completely and uniformly heated.
Quenching
JIS SKD11 steel tool material is an air hardening steel and will develop hardness on cooling in still air. To avoid scaling and prevent decarburization of the work piece surface, controlled atmosphere or vacuum furnaces are recommended. If these furnaces are not available, pack hardening, salt baths or wrapping the piece in stainless steel foil will provide some degree of surface protection in the hardening process. Parts should be allowed to cool to 150F, or to where they can be held in the bare hand, and then temper immediately.
Tempering
The tempering temperature on material JIS SKD11 steel may be varied according to the desired hardness. JIS SKD11 steels can be tempered at 204°C (400°F) for achieving Rockwell C hardness of 61 and at 537°C (1000°F) for a Rockwell C hardness of 54.
