Stainless steel round bar is a solid cylindrical rod made of stainless steel. It is used in a variety of applications such as construction, manufacturing, and various industries depending on the alloy and grade of the stainless steel used. The round bar can be supplied in different diameters, lengths, and finishes such as hot-rolled, cold-rolled, ขัดเงา, and centerless ground. Stainless steel round bars are popular due to their exceptional corrosion resistance, ความทน, and aesthetic appeal. It is commonly used for making shafts, fasteners, screw machine parts, valves, and pumps. It is also seen in the food and beverage industry as well as in marine applications due to its resistance to harsh environmental conditions.
