826M40 Steel (1.6747)

826M40 is a low-alloy steel that contains chromium, molybdenum, and nickel.

The alloy is also known as 1.6747 steel and falls under the British Standard BS 970-1955. This steel grade offers high strength, toughness, and good hardenability, making it suitable for various applications, particularly in the aerospace and oil and gas industries.

  • Good hardenability
  • Impact resistant
  • Good corrosion resistance
  • Suitable for high-stress applications

826M40 steel can be heat-treated to achieve high hardness and strength, which makes it useful in applications that require components to have excellent wear resistance. The alloying elements form carbides and promote martensite formation during quenching, which contributes to the steel's hardness.
