Questions and Answers

Do I need to use a heat sink?

Yes, installing a removable, snug fitting "heat sink" machined out of steel or aluminum into the bore is recommended to minimize distortion during the finish welding process.

Is 4130N Chromoly Steel stronger than Mild Steel?

Yes. 4130N Chromoly steel has a significantly higher tensile strength than mild steel, making it a preferred material for high-stress components. Ideal for fabrication of suspension, linkage components, and applications where maximum strength-to-weight ratio is required.

Can I weld Mild Steel to Chromoly Steel?

Yes, it is a very common practice. Mild Steel and 4130N Chromoly Steel can be welded together using the proper welding process and the correct filler rod.

Do I need to normalize a component or chassis made of 4130N Chromoly Steel after welding?

Some applications may require normalizing while others may not. This is a complex topic and can't be adequately addressed in a short paragraph. Please call our tech team at 800-530-9494 to discuss your specific project.
