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.

Applications:
T1 tool steel is usually used in the manufacture of all kinds of cutting tools,such as turning tool,
milling cutter,reamer,drill bit,saw blade,twist drill, also highly suitable for cold-forming tools such as cold extrusion rams and dies,
as well as plastic moulds with elevated wear resistance and screws.
