We offer you A36 and 1008 carbon steel (mild steel) in three surface finishes based on the most popular thicknesses:
Our mild steel is the go-to choice for fabricators, welders, machinists, prototypers, and anyone else who needs a strong, reliable part that is easy to work with.
Plus we’re easy to work with, too.
With our three offerings of mild steel, it can be challenging to know which best suits your current project, so we’re going to help clear that up for you. If you have any more questions that weren’t covered here, be sure to email us at support@sendcutsend.com and our applications engineers will get back to you.
Our cold-rolled carbon steel is our customers’ favorite material to work with. Cold-rolled is basically just hot-rolled steel with additional processing. Those additional processes give it a cleaner edge, better surface quality, and more exact dimensions. Cold-rolled has exceptional refinement and tends to be a little stronger and harder than hot-rolled. For these reasons, cold-rolled is better suited for bending and fabrication.
Our hot rolled carbon steel is commercial mild steel, found in most industries as it offers good weldability and machinability. It’s sturdy and easy to work with. It has a scaled surface finish from the cooling process and as a result, it is free of internal stresses sometimes associated with further processing. Hot rolled steel can be used in bending but is more prone to cracking.
HRP&O steel is much smoother and easier to finish than the cheaper “mill finished hot-roll” that most steel centers sell. HRP&O is just hot-rolled steel that is subjected to an acid bath in order to remove scale mill. Then it has some dry oil applied to prevent rusting. Overall, it has a nicer finish.
SendCutSend is always here to assist in choosing the right version of your material for your specific needs.
