Is AISI 4130 weldable?
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.
CAN 4130 steel be welded?
4130 chrome-moly can be welded with the TIG or MIG process. Preheat is generally not needed for thinner sections (0.120-in), but for tubing larger than 0.120 a 300F-400F preheat is needed to obtain acceptable results. A common filler metal choice for welding chrome-moly is ER80S-D2 .
Is AISI 4340 weldable?
Welding. This grade is readily welded in the annealed condition, but welding in the hardened and tempered condition should be avoided where possible because of the effect on mechanical properties. Welding in the nitrided or flame or induction hardened conditions is not recommended.
What are the properties of 4130 steel?
4130 steel properties
- Density – 7.85 g/cm.

- Machinability – 72% (in annealed state)
CAN 4130 chromoly be MIG welded?
Chromoly can be welded by TIG or MIG welding.
Is TIG weld stronger than MIG?
Precision: TIG welds are more precise and have a higher general quality than MIG welds. Cleaner process: The TIG process is cleaner and better for the environment. No need for filler: TIG welding doesn’t require filler material. Greater control: The pedal used allows for foot control to adjust heat input.
What’s 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.
Can you stick weld 4130 chromoly?
4130 chromoly matches the material to be welded, which makes it an option for chromoly welding. However, it cannot be used with Thin Wall Tube.
Can you heat treat 4130?
Because of its high hardenability, 4130 steel responds well to heat treating, which offers advantages for many applications. But, this material can also vary in mechanical properties as a result, making it challenging to select a filler metal that matches its strength in a given condition.
