Applications:Stainless Steel 420 round bars find their place in a wide range of industries, including cutlery manufacturing, surgical instruments, molds, and some automotive and aerospace components. Their hardness and wear resistance make them an essential material for products that need to maintain their edge and shape over time.


Heat Resistance: While not as heat-resistant as other stainless steel grades, 420 can still maintain its properties at elevated temperatures. This makes it suitable for applications in environments with moderate heat exposure.


Quality Assurance

To preserve the high standards of our selection of industrial round bar, we have always adhered to a systematic quality management process.

Team OF Experts

Our staff of experts is vibrant and talented, and they have always been our largest supporters and contributors to our success. Our vision is to create a world of round bar.
