ciably more expensive than the C-Mn steels they were to supercede. The world-wide steel industry met this demand with the development of a complete family of high-strength, low-alloy steels (HSLA) to be used in the hot- rolled, cold-rolled or heat-treated condition. Candidate steels were expected HOT ROLLED - AK SteelHIGH STRENGTH LOW ALLOY STEEL (HSLAS) For high strength or Structural Steel (SS) applications, Hot Rolled Steels are also available (shown in Table 2). HSLAS is intended for applications where greater strength or weight savings are important. The increased strength of HSLAS is achieved from niobium (Nb) or vanadium (V) additions.
In addition, HSLA steels are a good option when the application requires high strength in challenging environmental conditions or when other specific mechanical properties are needed. Successfully welding HSLA steels requires attention to several factors, including heat input, interpass temperatures and surface cleaning. Its also important High Strength Low Alloy (HSLA) Steel - IMOAHSLA steels are available today with traditional ferritic-pearlitic, bainitic, martensitic and multiphase microstructures, each available in hot- or cold-rolled steels.
