Supreme Steels

T4

Product Description:

T4 tool steel is a high-carbon, high-chromium tool steel with a tungsten base that offers excellent hardness, wear resistance, and resistance to softening at elevated temperatures. T4 is commonly used in applications requiring high performance at high speeds, such as cutting tools, forming tools, and dies. It is particularly known for its excellent wear resistance, toughness, and the ability to maintain hardness even under extreme thermal stresses. T4 is less commonly used than some other tool steels but is still valuable in situations where high strength and resistance to heat are critical.
