What does AISI 4130 mean?
What does AISI 4130 mean?
AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. 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.
What kind of material is 4130?
About 4130 (E4130) 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.
What should be the PWHT temperature of AISI 4130 material?
4130 alloy steel is typically normalized at 900 °C (1650℉), and should be cooled at a specified temperature in still air.
What is the equivalent material for AISI 4130?
Alloy 4130 (AISI 4130) is a chromium molybdenum alloy steel. 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).
What does 4130 mean on a bicycle?
The most common type of steel used for bikes is chromoly, and 4130 chromoly is the most widely recognized. So what does chromoly mean and what do the numbers 4130 refer to? Steel is an alloy of iron and other metals.
How strong is 4130 steel?
Both are important measures for designers, but yield strength is a vital component in structural applications where this value can never be exceeded. 4130 steel’s tensile yield strength is 435 MPa (63100 psi), which is surprisingly low when compared to other steels.
