Materials High Strength Low Alloy (HSLA)

High Strength Low Alloy Steel Tubing

High Strength Low Alloy steels have been created to achieve stronger steels while improving formability and weldability as compared to conventional carbon steels with similar strength levels. One of the key additions are small amounts of alloying elements. These quantities are too low to consider these steels as alloyed steels, therefore a family of HSLA steels were developed. Use of fine carbide formers such as vanadium, columbium (niobium), and titanium, have proven very effective in increasing strength levels of the steel, enough so that the carbon levels could drop significantly. The lower carbon content improves weldability, formability, and toughness.  The small additions of vanadium, columbium, and/or titanium alloy both grain refinement and precipitation strengthening during the hot rolling process.

Do you have questions about high strength low alloy steel tubing?  We would love to discuss your specific needs and how we can accommodate them!

What are the Benefits of HSLA Tubing?

  • Offers customers lightweight options; designing products with lighter weight via removing wall thickness by increasing overall strength.
  • Meet demands for higher strength tubes
  • Increased formability and toughness at strength levels beyond conventional carbon steels
  • Wide selection of different minimum strength levels for flat coil products to be cold-worked and welded into tubular products
  • Available in Hot Rolled or Cold Rolled
  • Available bare or galvanized
  • A variety of HSLA grades are available ksi [mpa]
    • ASTM Grades 45[310], 50[340], 55[380], 60[410], 65[450], 70[480], 80 [550]
    • SAE Grades 5[300], 50[340], 55[380], 60.9[420], 71[490], 80 [550]
    • Ultra high strength steels GR 90[620], 100[690]
