True or False: Cold-rolled steel achieves a better surface finish than hot-rolled steel.

Cold-rolled steel does indeed achieve a better surface finish than hot-rolled steel, making the statement true. The cold-rolling process involves rolling the steel at room temperature, which results in a smoother, denser, and more uniform material. This process enhances the steel's mechanical properties and makes it ideal for applications where a precise finish is essential.

Hot-rolled steel, on the other hand, is processed at elevated temperatures, which can leave a rougher surface finish due to oxidation and scale that forms during the heating process. While hot-rolled steel may be more cost-effective and easier to work with for some applications, in terms of surface quality, cold-rolled steel is superior, thus affirming the true nature of the statement.

The other responses may suggest variability in the quality of the steel based on the manufacturer or application, but generally, cold-rolled steel is recognized for its higher finish quality compared to hot-rolled steel across a wide range of manufacturing contexts.
