Stainless steel round tube is a hollow, long, round steel bar with a wide range of uses. It is used in industrial pipelines for transportation in the fields of petroleum, chemical industry, medical treatment, food, light industry, mechanical instruments, etc., as well as mechanical structural parts. In addition, under the same bending and torsional strength, stainless steel pipes are lighter in weight, so they are also widely used in the manufacture of mechanical parts, engineering structures, and are also commonly used in furniture, kitchen utensils, etc.

Stainless steel hardness measurement standards

Brinell hardness: Among the standards for stainless steel pipes, Brinell hardness is the most widely used, and the indentation diameter is often used to indicate the hardness of the material
Rockwell hardness: An indentation test method that measures the depth of the indentation
Vickers hardness: Also an indentation test method that can be used to measure the hardness of very thin metal materials and surface layers.

Austenitic stainless steel has paramagnetism

The stainless steel round tube has good corrosion resistance and high resistance to intergranular corrosion, and is widely used in automobile exhaust systems.

Excellent high-temperature oxidation resistance, not easy to expand and contract.
High thermal conductivity, uniform thermal conductivity, very suitable for occasions with heat exchange purposes.
Better creep resistance, less deformation under long-term stress.
Low production cost, so ferritic stainless steel products are developing rapidly.
Easy to cut and process.
High yield strength, and the yield strength is similar to that of ordinary carbon steel, with slightly lower elongation, but low tendency to work hardening, easy to cold heading, easy to cut, and low processing cost.
Ferritic stainless steel is not easy to rebound in cold forming
Not prone to stress corrosion cracking.
