Kanish Metals is a reliable manufacturer and supplier of High Speed Steel T42 Bars, headquartered in Dubai, UAE, offering premium tool steel solutions designed for superior cutting performance and abrasion resistance. T42 is cobalt-containing tungsten-based high speed steel with outstanding hot hardness, wear resistance, and cutting efficiency. Kanish Metals supplies T42 bars in sizes and specifications as required, produced to international quality standards. With an emphasis on accuracy, consistency, and timely delivery, Kanish Metals caters to a broad spectrum of industries such as aerospace, automotive, die and mold making, and general engineering throughout the UAE and international markets.
High Speed Steel T42 has approximately 1.3% carbon, 8% cobalt, 9% tungsten, 3.8% chromium, 1.5% vanadium, and traces of molybdenum. Its high content of cobalt and tungsten is responsible for providing T42 with outstanding red hardness, so that cutting edges retain the steel at temperatures above 650°C. T42 is hardened to 66–68 HRC by good heat treatment and possesses excellent wear resistance, toughness, and thermal softening resistance and can be used for aggressive and high-speed machining applications.

Yes, T42 Alloy High-Speed Steel Bars can be heat treated. They are typically hardened through heat treatment processes like quenching and tempering to enhance hardness, wear resistance, and performance.
Welding T42 High-Speed Steel Bars is challenging due to their high carbon content and hardness. If welding is required, preheating and post-weld heat treatment are often necessary to prevent cracking and ensure strength.
T42 High-Speed Steel Bars should be stored in a dry, cool environment to prevent rust and corrosion. They should be kept off the ground, ideally on wooden or plastic pallets, and protected from moisture and extreme temperatures.
High Speed Steel T42 Bars are generally employed in cases where high hardness, cutting accuracy, and thermal stability are required. The most common applications are twist drills, reamers, taps, end mills, broaches, and gear-cutting tools. T42 is particularly well suited for hard-turning applications such as stainless steel, titanium alloys, and heat-resistant superalloys. It is also employed in cold forming dies and precision cutting tools where deformation resistance and long tool life under heat and load are essential. T42 bars provide high productivity, dimensional stability, and durability in the most challenging cutting conditions.
