How much carbon does 4130 steel have?

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%.

Is 4130 a medium carbon steel?

What is 4130 steel? AISI 4130 alloy steel is a medium carbon, low alloy steel in ASTM A29 standard. ASTM 4140 steel is also commonly referred to as a chromoly steel, or chrome moly steel, containing nominally 0.28-0.33% Carbon, 0.8-1.1% Chromium and 0.15-0.25% Molybdenum.

How strong is 4130?

4130 steel’s tensile yield strength is 435 MPa (63100 psi), which is surprisingly low when compared to other steels. This is not to say that 4130 steel is weak; in fact, it far surpasses most aluminum alloys.

How strong is chromoly tubing?

Tubing Types

Tubing Material Yield Strength Tensile Strength
1010 ERW 32,000 psi 45,000 psi
1020 DOM 70,000 psi 80,000 psi
4130 Chromoly 70,000 psi 90,000 psi

Is 4130 a high strength steel?

Type 4130 steel has a Rockwell hardness of 92, which is high for steel and shows why this material is so tough.

Is 4130 steel corrosion resistant?

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.
