4330V - 2% Nickel-Molybdenum-Vanadium Through Hardening Steel

Surcharge

The Scrap surcharge has reduced for February 2019 as a consequence of lower production volumes at the end of 2018 and a realignment with other European scrap surcharges.

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

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.

Typical applications of 4330V grade steel

  • Subs
  • Crossovers
  • Reamers
  • Drill shoes
  • Drill jars
  • Tools
