FLEXOR steel is both unique in its chemistry as well as its wide variety of properties. FLEXOR steel is a Chromium-Molybdenum-Tungsten alloy steel which exhibits a fine grain microstructure. All FLEXOR steel heats are a vacuum degassed, ladle refined, electric arc furnace melt (EAF & LF & VD). All FLEXOR steel is forged or rolled from bottom poured ingots. FLEXOR steel has a minimum ingot reduction ratio of 3.5:1.
FLEXOR steel's unique residual chemistry is a special blend that adds to machinability without sacrificing properties.
FLEXOR is typically stocked in an as rolled condition. This means that when FLEXOR is rolled or forged from an optimal reduction ratio and cools in open air from 1700 F a fine grain microstructure is formed. This also gives the bar a consistent toughness measuring 28-32 HRC throughout the bar.
It is important to note that FLEXOR steel does not need to be normalized or annealed prior to hardening from this condition. This makes FLEXOR extremely versatile especially when it comes to thermal treatments.
