There are a lot of rods and pipes and steel products around us. Their surfaces are almost the same, and they are similar to round steel.
The smooth rod is a product that has only been subjected to a buffing treatment, that is, a process of polishing the original rod without performing chrome plating, rolling processing, and the like. Because its surface hardness is relatively low, its smoothness is better than chrome-plated rods.
Smooth rods are generally made of stainless steel, and different materials have different functions. Some of the smooth rods contain molybdenum and have low carbon content, and are excellent in pitting resistance in marine and chemical industrial environments. Some smooth rods have good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, and no heat treatment hardening.
