4130 Chromoly steel is a low carbon alloy steel (Chromium and Molybdenum) that excels in structural applications and welding, along with many other high-stress, high-performance projects.
4130 Chromoly steel is a durable metal meant for long-lasting projects. If what you’re making needs to withstand extreme pressures and temperatures over time, Chromoly might be the metal for you. The reason for this is in one of its key properties: Creep Strength.
When you use this material in high-stress applications, you can be sure that it will stay in place and hold its shape for longer. Hence why it’s often used in bicycle frames, roll cages, and airplane structures all over the world.
If you’re looking at something a little smaller, like a gear or cog. 4130 Chromoly steel’s excellent heat treatability and machinability make it an ideal fit for strong, tiny parts.
We source this high-demand metal through trustworthy suppliers with verifiable industry credentials so you don’t have to worry about it. You’ll know that our 5052 aluminum sheets are ready to be transformed into your greatest ideas.
