Hot Rolled (HR) Bar

Because of Millennium's network of suppliers, we have access to a diverse range of grades of hot rolled bar such as 1015 and 4140,as well as sizes both round and square, at competitive prices. Also, we offer rounds, square, hex, and flat shapes in hot rolled bar.

Since hot rolled steel can be produced in masses, it can be sold at lower prices. And because hot rolled steel is cooled down at room temperature, referred to as normalizing, the steel's microstructure changes, leading to an increase in ductility and toughness. In comparison to common unprocessed steel, hot rolled steel exhibits much greater workability and formability.

A few applications for hot rolled steel include

  • Railroad tracks
  • Screws and bolts
  • Pipes 
  • Vehicle frames
  • Pistons
  • Constructions 

Features of Our Hot Rolled Bar

For hot rolled steel bar, diameters up to at least 10.5 inches round are available, with the possibility of larger sizes. Materials that Millennium works with for bar products are as follows: 

  • 12L14, 1215, 1018, 1117, 11L17, 1030, 1035, 1045, 1137, 1141, 1144, 11L44, 8620, 86L20, 4140, 41L40, 1541, 52100, per ASTM A108 Standard, 1144 per ASTM A311 Class B

Our 1045 hot rolled bars and 4140 hot rolled bars are preferred by many customers. 1045 is common because of its balance of characteristics ranging from higher strength, decent weldability, and impact properties. 4140 steel is good for its high toughness, torsional strength, and high fatigue strength.
