Steel 4330 Mod

4330 Vac Mod AMS 6411 steel is a variation of 4330 steel with a few chemical properties improved by the addition of the element  vanadium. 4330V Mod is a low alloy steel.  Capable of being heat treated to substantial strength levels. It  is primarily supplied  in the 220 to 240 ksi strength range. Alloy 4330 Vac Mod AMS 6411 steel is produced by the vacuum consumable electrode melting process to provide optimum cleanliness and preferred ingot structure.

The  low carbon content of Alloy 4330V Mod makes it particularly useful in end use applications involving shock loading or stress concentration. The alloy offers strength and high resistance to crack propagation and exceptional low temperature impact properties.

There are many applications of 4330 Vac Mod AMS 6411 in parts that need hi performance alloys, such as aerospace, defense, and power generator . 4330 V Mod AMS 6411 steel is primarily used in the oil industry for tools and drilling equipment.   Also used for bolting, shafts, landing gear and air frames. In the aerospace industry.
