IMI Alloys India LLP is today’s market’s most prestigious and affluent industry. Our collaboration has brought success to many upcoming industries. M42 High Speed Steel Flat Bars are used for rigorous industrial uses as they can bear work stresses. Their tensile strength is considerably greater than any other bars. The component of steel offers the product a unique rigidness and strength. Their yielding capacity is also high. These flat bars contain material compositions and contents like nickel, chromium, manganese, molybdenum, and the elements that protect these bars from destructive factors. The action of halides and chlorides is almost none in these products.
M42 High Speed Steel Flat Bars have thickness and width which are accurate and as per the assigned machine needs. They belong to the same molybdenum series of high-speed alloys with more cobalt content.

M42 High Speed Steel Flat Bars are designed to comfortably match any machine and device. Their assembling is far too easy and user-friendly. Our services have aided and given technical assistance to clients. We also manufacture customized industrial products with various specifications such as sizes, variations, styles, shapes, and dimensions. We maintained the quality and accuracy of our products. M42 High Speed Steel Flat Bars are very durable and stable. They perform well even at elevated temperatures and various concentrations. Extreme work pressure turns them unaffected. Surface deformation and pitting are never experienced by M42 High-Speed Steel Flat Bars as they are made up of the strongest metals.
The process involved in producing M42 High-Speed Steel Flat Bars are the newest methods and as per the latest trends. Our research and development team has special insight into improvising our techniques to meet worldly demands. These Bars are difficult to mold once manufactured and are sturdy for any working exposure. Flat Bars are preferably used for operations where hot hardness is highly demanded. Mostly, these bars are used in industrial applications and business sectors. The commercial operations are twist drills making, reamers production, bandsaw blades, cold work tools, and taps where these bars are used.
