Laser-cut 4130 Chromoly

Starting from $29

Are you looking for some tough custom gears? Maybe an automotive engine mount for your garage project? Or, do you need structural supports for a biplane frame? Well, you’ve just found them all and then some.

4130 Chromoly is a low carbon alloy steel (Chromium and Molybdenum) that excels in structural applications and welding, along with many other high-stress projects.

And it’s here at SendCutSend to help you get things done.

High Hardness
CORROSION RESISTANT
STRONG

4130 Steel and your next project

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.

This basically means that 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 used in bicycle frames, roll cages, and airplane structures all over the world.

But say you’re looking at something a little smaller, like a gear or cog. 4130 Chromoly’s excellent heat treatability and machinability make it an ideal fit for strong, tiny parts.

Show us your design and we’ll make sure you find the right fit!
