4330V - 2% Nickel-Molybdenum-Vanadium 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

4330V grade steel is a through hardening steel capable of very high strengths in large sections from hardening and tempering treatments, due to its high hardenability.

It is typically used for drilling parts where longer tool life and higher strength is required than conventional 4145. However, it does not meet the approval of NACE MR0175 due to its high nickel content.

The relatively low carbon makes this grade useful for applications involving shock loading or stress concentrations, and where good fracture toughness is required.

It can be welded, however preheating and post-weld heat treatment are desirable to prevent cracking. Good forgeability is also demonstrated but preheating and furnace cooling are recommended due to its high hardenability.

Size Range
