    About 440B Stainless Steel
    It is a high carbon, martensitic stainless steel product with good overall strength and moderate corrosion resistance in the hardened and tempered condition. The alloy must be free of scale and foreign particles if optimum corrosion resistance is to be achieved. 440B annealed product also offers similar machining characteristics when compared with high speed annealed steel grades. With such excellent hardness, the alloy also promotes good wear resistance. A hardness value of 60 HRC is achievable after heat treatment.

    Alloy 440B Stainless Steel is a high carbon chromium steel which is manufactured in rod, bar and coil. (AISI 440B ~ Stainless Steel).


    Material Properties
    This steel is designed to provide stainless properties with excellent hardness. In some respects it behaves similarly to tool steel. Chronifer M 17B resists corrosion from mild atmospheres, fresh water steam, ammonia, many petroleum products and organic materials and several mild acid environments.


    Availability

    • Bars Ø5-50mm: Cold drawn and polished
    • Bars Ø 10.00-350mm: Cold drawn, ground and polished
    • Bars Length : 2m- 6m. Surface roughness N5-N6

    Standard Tolerances

    • Diameter: 5-350mm
    • Out of roundness/cylindricity :1/2 of dia tolerance
    • Tolerance in length : +50/-0mm

    Corrosion Resistance
    This grade is used in the hardened and tempered condition for a good corrosion resistance. For optimum, corrosion resistance, surfaces must be free of scale and foreign particles.


    Heat Treatment

    • Soft annealing: 750-800ºC
    • Slow furnace cooling (2-4 hours)
    • Hardening: 1000-1080ºC
    • Max obtainable hardness 57-59 HRC

    Cutting Rate
    20-35m/min (approx value, depending on the lubrication oil, the cutting tools, the shape of parts)


    Stock Range
    Standard dimensions from Ø 0.80 to 24.00mm with many intermediate dimensions.
