High quality carbon structural steel is carbon steel with carbon content less than 0.8%. It contains less sulfur, phosphorus and non-metallic inclusions than carbon structural steel, and its mechanical properties are better. This kind of steel has a large output and a wide range of uses.


Generally, it is rolled (forged) into round, square and flat sections, plates and seamless steel pipes. It is mainly used to manufacture parts and components of general structure and mechanical structure, as well as building structural parts and pipelines for conveying fluids. According to the use requirements, sometimes heat treatment (normalizing or tempering) is needed after use.


Similar to AISI 1020, AISI 1025 is a low- to medium-carbon alloy appropriate for general engineering and construction applications. Offering good machinability, AISI 1025 can be normalized, hot- and cold-worked, or water quenched and tempered.


Applications of AISI 1025 Steel

  • Machinery parts
  • Construction components
  • Trusses
  • Building sections
  • Tool and die applications
  • Cold-extruded and case-hardened parts
