For decades, cemented carbide tooling has been the default choice for high-production machining due to its extreme hardness and wear resistance. However, global supply disruptions and unprecedented price volatility in tungsten<\/a>\u2014the primary raw material in carbide\u2014are forcing manufacturers to reevaluate long-standing material choices.<\/p>\n\n\n\n As tungsten supply tightens and costs rise, many shops are re-examining high-speed steel (HSS)<\/a>\u00a0as a practical and strategic alternative. While HSS was once considered a legacy material, modern HSS grades[conventional and Powder Metallurgy(PM) grades] and processing techniques make it a viable solution for many applications\u2014especially in today\u2019s uncertain raw material environment.<\/p>\n\n\n\n Tungsten is classified as a critical mineral\u00a0by the United States and many allied nations due to its importance in defense, aerospace, electronics, and manufacturing. Global supply is highly concentrated, with China accounting for more than 80% of worldwide mining and processing capacity.<\/p>\n\n\n\n Since late 2024 and throughout 2025, China has implemented stricter export controls on tungsten products, including ammonium paratungstate (APT), the key intermediate used to produce tungsten carbide. These controls have resulted in:<\/p>\n\n\n\n For manufacturers dependent on carbide tools, this volatility introduces real risks to cost stability, production planning, and customer commitments.<\/p>\n\n\n\n Cemented carbide tools typically contain 70\u201397% tungsten carbide, bonded with cobalt or nickel. This makes carbide tooling highly exposed to tungsten pricing and availability.<\/p>\n\n\n\n While carbide excels in high-speed, high-volume, and abrasive cutting environments, it also has drawbacks that are amplified during supply disruptions:<\/p>\n\n\n\n As tungsten prices surged through 2025, many shops found that carbide tooling no longer delivered the cost-per-part advantages it once did.<\/p>\n\n\n\n High-speed steel is an alloyed tool steel containing iron, carbon, and combinations of molybdenum, chromium, vanadium, and, in some grades, reduced or no tungsten. Unlike carbide, HSS relies on a broader and more diversified raw material base, making it less vulnerable to single-source supply shocks. Newer PM grades have been specifically designed as alternatives to tungsten carbide \u2013 PM M4<\/a>, PM T15<\/a>, and PM M48<\/a>.<\/p>\n\n\n\n 1. Supply Chain Stability 2. Lower Tooling Cost Volatility<\/strong> 3. Superior Toughness and Shock Resistance<\/strong> 4. Ease of Regrinding and Repair<\/strong> Transitioning away from carbide does not mean abandoning performance. Many applications are already well-suited\u2014or better suited\u2014to modern HSS grades, including:<\/p>\n\n\n\n In these use cases, HSS often delivers a lower cost per part, even if cutting speeds are modestly reduced.<\/p>\n\n\n\n Historically, carbide justified its cost through higher speeds and longer tool life. Today, the equation has changed. With tungsten prices elevated and supply constrained, manufacturers are increasingly prioritizing:<\/p>\n\n\n\nUnderstanding the Tungsten Supply Challenge<\/strong><\/h2>\n\n\n\n

High-Speed Steel: A Strategic Alternative<\/strong><\/h2>\n\n\n\n
Key Advantages of HSS in the Current Market<\/strong><\/h2>\n\n\n\n
<\/strong>HSS production is far less dependent on tungsten, and several grades (such as M1, M7<\/a>, and M42<\/a>) significantly reduce tungsten. This makes availability more predictable and pricing more stable.<\/p>\n\n\n\n
While HSS tools may wear faster than carbide in extreme conditions, their initial cost is substantially lower, and pricing has remained far more consistent during the tungsten shortage.<\/p>\n\n\n\n
HSS outperforms carbide in interrupted cuts, forming operations, broaching, and applications with vibration or impact. This reduces tool breakage and unplanned downtime.<\/p>\n\n\n\n
HSS tools can be sharpened and reconditioned multiple times, extending usable life and lowering total tooling spend\u2014an increasingly important advantage as shops seek to control costs.<\/p>\n\n\n\nWhere HSS Makes the Most Sense<\/strong><\/h2>\n\n\n\n
