What does the designation of SAE 4130 mean?
A. 4130 is a designation for a steel alloy that contains chromium and molybdenum among other elements. The exact composition range is defined in the standard SAE J404 [affil. link to spec at Techstreet] “Chemical Compositions of SAE Alloy Steels”.
What is the KSI of 4130?
29700 ksi
Type 4130 steel has a modulus of elasticity of 205 GPa (29700 ksi), which is higher than some high strength spring steels such a 9260 steel (read more in our article on 9260 steel).
What type of material is 4130?
4130 alloy steel
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 the difference between 4130 and 4140 steel?
4130 contains 0.28-0.33% Carbon and 0.40-0.60% Manganese, while 4140 contains 0.75-1.00% Manganese and 0.38-0.43% Carbon. – 4140 alloy steel has greater hardenability and strength than 4130. – 4130 steel is easier welding than AISI 4140 steel and its wear-resistant performance is lower than in 4140.
What is the difference between 4130 and 4140?
What is 4130 steel used for?
Easy to machine and hot work as well as cold work in the annealed state, it becomes significantly more challenging once the steel is hardened. 4130 steel can also be easily welded. It is typically used in structural applications, including gears, fasteners, and some aircraft exterior.
