Difference between A106B and 20 # steel

A106 and 20# steel are two of the most common and commonly used carbon steels, differing somewhat in specific chemical properties, mechanical 1 properties, and uses.
1. Difference in composition: A106B is a kind of carbon steel pipe with high carbon content in its composition; while 20# steel is a kind of high-quality carbon structural steel, which mainly contains iron, carbon and a small amount of alloying elements in its composition.

2. Application areas: A106B steel is mainly used in petroleum, chemical, electric power and other industrial fields; while 20# steel is widely used in machinery manufacturing, automotive, shipping and other industries.
3. Performance characteristics: A106B steel has high strength and good toughness, as well as good workability and weldability; while 20# steel not only has high strength, but also has good plasticity, toughness and cold bending properties, good heat treatment performance.

4. Appearance and process: A106B usually appears in the form of tubes for transporting fluids, while 20# steel is more in the form of plates, profiles, etc., for the manufacture of a variety of mechanical parts and structural components. During production, both undergo different heat treatment processes to optimise their mechanical properties.
