708M40 - 1% Chromium-Molybdenum Through 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.

Description
708M40 grade steel is a versatile low alloy steel that possesses good tensile and shock resistance properties combined with ductility.
Its resistance to wear can be considerably increased by flame hardening and it is also suitable for nitriding (for maximum wear and abrasion resistance).
Bars are often supplied in the hardened and tempered condition with a tensile strength range of 850-1000N/mm². The bars are readily machinable so that the components can be put into service without the cost of further treatment.
Bars can also be supplied in the softened state which require hardening and tempering, but will give increased machinability.
Typical applications of 708M40 grade steel
- Axle shafts
- Crankshafts
- Gears
- Induction hardened pins
