High strength and toughness: 4330 forging is a medium carbon chromium nickel molybdenum alloy steel with good hardenability, strength, and toughness. It has high yield strength and tensile strength, especially able to maintain good impact toughness in low temperature environments
Good processing performance: 4330 forgings have excellent mechanical properties after heat treatment, including high hardness (HRC 28 to HRC 50) and good hardenability. It has good processing performance and is suitable for optimal workability treatment at 1250 ° F (675 ° C)
Wide application areas: Due to its high strength, toughness, and good wear resistance, 4330 forgings are widely used in high-performance applications such as aircraft landing gear, petroleum industry, power transmission components, machinery, and bolted connections
Heat treatment process: The heat treatment of 4330 forgings includes annealing, normalizing, hardening, and tempering. The annealing temperature is 1510-1580 ° F (820-860 ° C), the normalizing temperature is 1600-1700 ° F (870-925 ° C), the hardening temperature is 1550-1600 ° F (845-870 ° C), and tempering is carried out according to the required strength level
330V steel, also known as AISI 4330V or UNS G43300, is a low-alloy high-strength steel belonging to the nickel chromium molybdenum alloy steel series. This type of steel is widely praised for its excellent hardenability, high strength, high toughness, and excellent fatigue resistance. In addition, 4330V steel also has the low-temperature impact toughness and tempering stability of C color, which makes it exhibit C color in various application scenarios.
chemical composition
The chemical composition of 4330V steel mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), chromium (Cr), nickel (Ni), molybdenum (Mo), and possible trace amounts of vanadium (V) added. The addition of vanadium is mainly to enhance the grain refinement effect of steel, thereby improving its strength and toughness.
Mechanical performance
After appropriate heat treatment, 4330V steel can exhibit better mechanical properties than CZ. Its yield strength and tensile strength are both high, while maintaining good toughness. In addition, the steel also has high impact toughness and fracture toughness, making it exhibit a C-color when subjected to high loads and complex mechanical environments.
