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.
