What is 4330 material?
4330 MOD VAR AMS 6411 is AISI 4330 Steel modified with the addition of Vanadium. It is a low alloy steel capable of being heat treated to high strength levels. Vanadium is added to improve impact strength and hardenability.
What is the material composition of AISI 4340 steel?
AISI 4340 is a low alloy steel containing nominally 0.4% C, 0.8% Cr, 0.25% Mo and 1.8% Ni. Higher strength levels up to 150 KSI 0.2% PS may be achieved by suitable heat treatment. Often used in preference to AISI 4140 at the higher strength levels because of its better hardenability and improved CVN impact toughness.
What is the composition of the AISI 4130 steel and what is it used for?
Aircraft quality 4130 alloy steel is a medium carbon, low alloy steel containing 0.15/0.25% molybdenum and 0.80/1.10% chromium as strengthening agents. This type of steel is also commonly referred to as a chromoly steel, or chrome moly steel. Due to its relatively low carbon content of 0.28/0.33%.
What is 4330V steel?
AISI 4330V is a Nickel Chrome Molybdenum (NiCrMo) hardened and tempered high strength alloy steel for applications in the oil and gas industry. It is typically used for oil tools and drilling jars due to its combination of high strength and exceptional impact properties.
What is ASTM A29?
ASTM A29 specification is standard specification for Steel Bars, Carbon and Alloy, Hot-Wrought, General Requirements. There are following kind of carbon and alloy steel bars under this standard: hot rolled carbon steel bar, cold finished carbon steel bars, hot rolled alloy steel bars, cold finished alloy steel bars.
What’s the difference between 4140 and 4340 steel?
However, 4340 has more carbon, while 4140 has more chromium. One of the most significant differences between the two metals is the inclusion of nickel in 4340 steel, which accounts for the metal’s greater strength and fracture toughness.
What is AISI 4340 steel called?
AISI 4340 steel is a medium carbon, low alloy steel known for its toughness and strength in relatively large sections. AISI 4340 is also one kind of nickel chromium molybdenum steels. 4340 alloy steel is generally supplied hardened and tempered in the tensile range of 930 – 1080 Mpa.
What is the difference between 4130 and 4140 steel?
4140 is similar in composition to 4130 except for the higher carbon content. The “30” in 4130 represents the carbon content by % of weight (0.28-0.33 % for 4130 vs 0.38-0.43 % for 4140). Because of its higher carbon content, 4140 steel has greater hardenability and strength than does 4130.
Why AISI 4130 is better?
The steel has good strength and toughness, weldability and machinability. AISI/SAE 4130 grade is a versatile alloy with good atmospheric corrosion resistance and reasonable strength. It shows good overall combinations of strength, toughness. and fatigue strength.
What is ASTM A434?
ASTM A434, 2006 Edition, May 1, 2006 – Standard Specification for Steel Bars, Alloy, Hot-Wrought or Cold-Finished, Quenched and Tempered. This specification covers hot-wrought and cold-finished quenched and tempered alloy steel bars.
What are the characteristics of 4330 steel?
General characteristics of Alloy Steel 4330 This is a fine-grained, medium carbon, chromium-nickel-molybdenum alloy steel with good hardenability, and excellent transverse strength and toughness. It also shows excellent low-temperature impact properties.
What is AISI 4330?
Alloy Steel 4330, also sold as AISI 4330, is a high-strength, chromium, nickel, and molybdenum alloy. Alloy Steel 4330 is heat-treatable, and offers good formability.
What is a 4330 bolt used for?
Popular in the oil, gas, and mining industries, 4330 features solid formability and machinability with terrific cold working characteristics. Other applications for 4330 include aircraft and power transmission components, machinery, and bolting.
What is 4330 VAC mod AMS 6411 steel?
The alloy is primarily used in the 220 to 240 ksi strength range. 4330 Vac Mod AMS 6411 steel is produced by the vacuum consumable electrode melting process to provide optimum cleanliness and preferred ingot structure.
