K310 Steel Supplier in India | Your Partner for High-Performance Tool Steel

K310 steel is a versatile and high-performance high-carbon, high-chromium tool steel known for its exceptional combination of toughness, wear resistance, and ability to perform in both cold and hot work applications. This grade is prized for its high hardenability and dimensional stability after heat treatment. At Jupiter Steels, based in Delhi, we are a trusted stockist and supplier of K310 steel, providing top-quality material to businesses throughout India, including industrial hubs in Manesar, Haryana, and beyond.


The outstanding performance of K310 tool steel is a direct result of its carefully balanced chemistry. The key alloying elements and their typical weight percentages are:

  • Carbon (C): 0.90 – 1.05%
  • Chromium (Cr): 4.80 – 5.50%
  • Molybdenum (Mo): 1.10 – 1.50%
  • Vanadium (V): 0.40 – 0.60%
  • Silicon (Si): 0.80 – 1.20%

  • Chromium (Cr) & Molybdenum (Mo): The combination of chromium and molybdenum provides excellent hardenability and hot strength. They form fine carbides that increase the steel’s resistance to wear and abrasion, while also ensuring the material can maintain its properties at elevated temperatures.
  • Vanadium (V): Vanadium forms extremely stable carbides that significantly increase the steel’s resistance to abrasive wear.
  • High Carbon (C): The carbon content is critical for achieving the high hardness and strength required for tooling applications after heat treatment.

After heat treatment, K310 steel can achieve a high working hardness, typically in the range of 58-62 HRC, making it suitable for a variety of demanding applications.

  • High Toughness: It provides a great balance of toughness and hardness, which helps prevent chipping and fracturing, especially in applications with high shock loads.
  • Good Wear Resistance: It offers good resistance to abrasive wear, extending the life of tools.
  • High Hardenability: It can be hardened with a controlled cooling process, which minimizes distortion.
  • Versatile Performance: The composition allows it to be used for both cold work and some hot work applications.

K310 tool steel is extensively used in a variety of tooling applications that require a balance of wear resistance and toughness. Key applications include:

  • Cold forming tools
  • Stamping and blanking dies
  • Hot shear blades
  • Forging dies
  • Rolls and mandrels

Q1: What is K310 steel used for?

: K310 steel is primarily used for tooling that requires a strong balance of high wear resistance and toughness, often in both hot and cold work applications.

Q2: What is the main benefit of using K310 steel?

A: The main benefit is its excellent toughness-to-hardness ratio, which allows it to withstand high shock loads while still providing good wear resistance.

Q3: Is K310 suitable for continuous high-temperature use?

: While it has good hot strength, it is not a dedicated hot work steel. For applications with continuous high temperatures, a more specialized hot work grade may be more suitable.
