Specifications

T1 Steel is the most widely used tungsten type of high speed steel according to ASTM/A600 standard.As original HSS,T1 steel has good abrasion resistance, high toughness, high hardness (62~66HRC) ,good red hardness,and easy to grinding. T1 steel can still keep the cutting performance of cutting tools when working temperature is below 600 ℃.The general purpose T1 tool steels and the high-vanadium-cobalt T15 are most commonly used in the T series.
