AISI 4330V / SAE 4330V
AISI 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.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.
AISI 4330V mod. can be used as a universal quenched and tempered steel in many applications. There is the advantage in high toughness (in deep temperatures also) together increased strength properties. It gets these great properties by Vanadium alloyed modification. The largest amounts of these steel grades are used in Mechanical Engineering (high-strength structures) and is widely used in the oil and gas sector.
AISI 4330 V is a chromium, nickel, molybdenum, vanadium high strength low alloyed steel suitable for downhole tools and drilling jars. It offers improved hardenability and the ability to achieve higher tensile strengths and impact.
