Product Description
ASTM A600 T1 Tool Steel - High Speed Steel
1: AISI T1 Steel Introduction
T1 steel is a tungsten-series high-speed tool steel, with its American grade belonging to the ASTM A600 standard. This material contains multiple carbide-forming elements, offering exceptional red hardness, high wear resistance, and good tempering resistance. T1 steel is typically used in a quenched and multiple tempered condition, achieving a hardness of 63-65 HRC. It is widely employed in manufacturing cutting tools, drill bits, milling cutters, and wear-resistant components for high-temperature operating conditions.

6: Goods available in China
If you want to purchase T1 steel from China, you can find stocks for T1 round bars in the market, but the available specifications are often limited. For other forms like T1 flat bars or billets, there is typically no stock available, and they require custom production. The MOQ for such custom orders is generally low, as the raw material can be sourced with relative ease. If your application allows, considering alternative high-speed steel grades like M2 could lead to cost savings and better availability.
