Janitorial and Sanitation Supplier serving Owen Sound and surrounding areas in Grey and Bruce Counties.

When tooling components that require a high degree of accuracy, using a substandard tooling steel can not only compromise the quality of the part but could lead to unscheduled downtime. Super high speed steel offers unparalleled precision, abrasion resistance and reliability in high heat, high speed and high impact use. While HSS steel is ideal for tooling, it has a tendency to get brittle at extremely high temperatures, so it is not suitable for applications where a more malleable steel is needed.

What is high speed steelused for

High speed steel, also called HSS, is comprised of steel clad in metal carbide. Metal carbides can be made of tungsten carbide, molybdenum or vanadium. The new structure composed of the substrate and carbide contains high carbon content and provides exceptional characteristics that exceed either on their own. Other alloys can’t offer the same structural hardness or ability to be machined at high speeds.

Compared to lower alloy high speed steels, it offers a longer cutting tool life. PM T15 is an ideal choice for cold work tooling compared with high carbon, high chromium die steels.

High speed steelcutting tools

This high speed steel shares the qualities of high wear resistance and impact toughness with M42 steel but is unique in that it has superior bend strength. This purple hardness, cobalt series steel grade is formed from clean steel with fine grain and small carbides.

Steel has always been a popular choice for a high-performance tool metal. However, there is a subset of the hardened steel alloy that is superior for high wear resistance. It can be machined at high speeds, earning the name super high speed steel.

Since it can handle notoriously difficult to machine nonferrous superalloys, M42 is often used in manufacturing parts for oil, aerospace, and power generation sectors.

Significant elements of super high speed steel alloys include carbon, chromium, tungsten, molybdenum, vanadium, or sometimes cobalt in varying combinations. The addition of cobalt increases the hardness and cutting efficiency in applications where high temperatures are present.

There are many grades of tooling steel that are perfect for high speed manufacturing applications. Two of those are M42 steel and PMT15 steel.

M42 steel is composed of 1.1% carbon, 3.9% chromium, 1.6% tungsten, 9.5% molybdenum, 1.2% vanadium, and 8.25% cobalt. Some of the most common uses for M42 steel are form tools, header tooling, punches, thread roll dies, twist drills, broaches, taps, milling cutters, reamers, end mills, and blades.
