835M30 - 4.5% Nickel-Chromium-Molybdenum Through Hardening Steel

Surcharge

Scrap has fallen again for June 2019 on the back of reduced demand. Combined with slight falls in alloys, this has seen an overall reduction in surcharges this month.

Surcharge information as listed via Liberty Speciality Steels where possible, other based on mean chemical analysis for the given grade.

Description

835M30 grade steel is a 4.5% Nickel-Chromium-Molybdenum through hardening steel which has the ability to harden in fairly large sections, giving strengths of over 1550N/mm².

Due to its high hardenability, these strengths are achievable by air from the hardening temperature.

This steel is used for applications requiring high tensile strengths for which more drastic quenches would produce distortion or cracking, especially in parts of intricate design.

Typical applications of 835M30 grade steel

  • High duty gears
  • Pinions
  • Aero engine connection rods
  • Differential shafts and other transmission components
  • Airframe forgings
  • Heavy roller bearings
  • Breech mechanisms
  • Small arms components

835M30 steel is still often referred to as EN30B steel - its equivalent grade under the previous BS 970: 1955 standard.
