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%. These 4130 steel properties offer exceptional weldability.

Aug 26, 2015 · Heat Treating. Heat Treating is a term that goes hand in hand with 4130 chromoly very frequently in BMX. What is heat treating exactly? It is a process where extreme heating and / or cooling is applied to the chromoly to alter its properties that can change hardness, strength, toughness, ductility and elasticity in the material.
AISI 4130 steel is heated at 871°C (1600°F) and then quenched in oil. This steel is usually heat treated at temperatures ranging from 899 to 927°C (1650 to 1700°F). This steel is usually heat treated at temperatures ranging from 899 to 927°C (1650 to 1700°F).
Alloy 4130 is a widely used Aircraft Steel due to its weldability, ease of fabrication and mild hardenability. The hardenability and weldability of Alloy 4130 are considered equivalent to 8630 (MIL S 6250) . Alloy 4130 is also vacuum degassed to meet the magnetic particle inspection standards of AMS 2301. Typical Mechanical Properties
Jun 08, 2011 · Heat treatment results (hardness, microstructure, properties) are dependent on such factors as the exact material chemistry, part section thickness and the method of heat treatment. For 4130 steel, the recommended heat treatment  consists of heating to austenitizing temperature, typically 1600°F (870°C), followed by water quenching.
ASTM SAE 4140 (AISI 4140 steel) is Cr Mo series low alloy steel, mechanical properties, heat treatment, rockwell hardness, welding, equivalent material uses
4130 Steel Bar Stock Alloy Bar TW’s cold drawn seamless 4130 alloy steel bar, rod, and wire is a lighter weight, higher strength alternative to carbon steel. As the market leader in 4130 alloy steel, TW Metals delivers a full range of 4130 round bar.
Dec 13, 2016 · AISI 4130. Chromoly steel is actually alloy steel grade 4130. The “30” at the end of the grade number designates that it has approximately 0.30% carbon by weight. The added chromium and molybdenum help to give the steel different properties from its mild steel counterpart, AISI 1030, even though they have the same percentage of carbon.
Alloy 4130 is a widely used Aircraft Steel due to its weldability, ease of fabrication and mild hardenability. The hardenability and weldability of Alloy 4130 are considered equivalent to 8630 (MIL S 6250) .
These 4130 steel properties offer exceptional weldability. With the proper heat treatment it is also readily machined. Annealing 4130 (E4130) alloy steel offers excellent ductility. 4130 steel can also be normalized or otherwise heat treated. Steel 4130 (E4130) has an excellent strength to weight ratio and is considerably stronger and harder
Heat Treatment Heating at 1600 °F followed by an oil quench will harden the 4130 alloy. For best results a normalizing pre hardening heat treatment may be used at 1650 to 1700 °F followed by the 1600 °F soak and oil quench. Forging Forge at 2200 °F maximum down to 1750 °F. Hot Working 4130 in the annealed condition has excellent ductility.
Hardening of AISI Alloy Steel 4140. SAE 4140 alloy steel is usually supplied ready heat treated to hardness in 18 22 HRC. If further heat treatment is required, then heat to 840 oC – 875 oC, hold until temperature is uniform throughout the section, soak for 10 – 15 minutes per 25 mm section, and quench in oil, water, or polymer as required.
Alloy Steel 4130 can be hardened by heat treatment. Alloy 4130 Steel Applications Alloy Steel 4340 is another alloy known for superior mechanical properties. AISI 4340 is a heat treatable, low alloy steel containing nickel, chromium and molybdenum. It is known for its toughness and capability of developing high strength in the heat treated
