635M15 - Low Alloy Nickel-Chromium Case Hardening Steel

Surcharge

Both Scrap and most alloys saw a small increase going into April, meaning surcharges for the majority of grades increased slightly.

Nickel has been rising steadily (albeit not significantly) in recent weeks and therefore we would expect to see this filter through to the surcharges in the coming weeks.

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