945M38 - 0.7% Nickel-Chromium-Molybdenum Through Hardening Steel
Surcharge Information
Due to the UK’s mostly commonly recognised surcharge mechanism no longer being openly published to the UK market we are unable to provide specific surcharge information on our website at this stage.
We are currently working with our suppliers to establish alternative mechanisms in order to provide a comprehensive and transparent view of global surcharge variations.
Look out for our improved surcharge pages appearing in the coming weeks.
Description
945M38 grade steel is a low alloy steel capable of being quenched and tempered to produce tensile strengths upon 925N/mm² in small sections and 850N/mm² in medium sections, combined with good ductility and resistance to stock.
In the hardened and tempered condition, machinability is comparable to that of other low alloyed steels; approximately 45-55% that of mild steel.
Typical quench and temper regime: Austenitise at 840-870⁰C followed by Oil Quench. Temper between 550-680⁰C.
Material will exhibit hardness of 55-60HRc in the as quenched condition.
Size Range
32mm - 240mm Dia
