    About Steel
    industrial info icon

    Compare over 50 grades of steel and cast iron to find the right material for you—all with material certificates for traceability.

    Tight-Tolerance Ultra-Heat-Resistant M42 High-Speed Tool Steel Rods

    Image of Product. Front orientation. Steel. Tight-Tolerance Ultra-Heat-Resistant M42 High-Speed Tool Steel Rods.
    Machine saw blades, end mills, and other cutting tools that stay hard and sharp at top speeds and temperatures. M42 runs faster and hotter than other grades of high-speed tool steel, so it slices through material as tough as titanium without softening or wearing down. Precision ground and held to a strict tightness tolerance, this steel is all set to turn in your lathe. Also known as cobalt steel.

    Dowel Pins

    Image of Product. Front orientation. Dowel Pins. Standard Tolerance, Plain Head.
    Precisely align machine parts and prevent movement during assembly. These dowel pins are machined to tight tolerances and have a uniform diameter for a snug fit. They can also be used as a pivot, shaft, or hinge to join moving components. Since dowel pins can be hard to remove, they are best suited for permanent fixtures that don't require frequent adjustments or disassembly.
    Steel
    High-Strength Alloy Steel—Our strongest, most wear-resistant pins, these won't bend or break from vibration. Use them for high-stress applications, such as mounting and aligning hydraulic cylinders and injection molds. They perform best in dry environments since moisture will cause them to rust.

    Brazing Alloys for Tight Gaps

    Image of Product. Front orientation. Brazing Alloys. Brazing Alloys for Tight Gaps.
    When melted, these alloys form a thin liquid that easily flows into smaller gaps than standard brazing alloys. They don’t contain cadmium, so they’re safer than other brazing alloys with cadmium and help you meet industry regulations.
    BAg-36—BAg-36 alloys are often used in the piping and automotive industry.
