What Is High Strength Low Alloy Steel (HSLA)?

• High strength low alloy steel (HSLA) is a range
  of steels which are engineered specifically for
  performance rather than for any specific chemical
  content. Small alloying elements such as
  Titanium, Columbium and Vanadium are introduced
  at the production stage to provide added
  strengthening to the material.
• HSLA steels are popular due to increased market
  demand for high yield steel products. Any steel
  with good forming qualities and high impact
  strength characteristics will ultimately provide
  a low-cost option in the long-term as the steel
  will last, even under heavy load bearing and
  heavy wear environments.
• Examples of HSLA steels
• Abrasion Resistant Steel
• Used throughout the mining and earth moving
  industry, abrasion resistant steel is engineered
  specifically to last. The material is martens
  tic and displays excellent hardness
  characteristics which makes it resistant to the
  effects of heavy wear and increases in surface
  pressure. The material can provide an impressive
  yield strength of up to 1250 MPa (Mega Pascal's)
  which is dependent on thickness.

• Armour Plate
• Displaying excellent yield and tensile strength,
  armour steel plate is in essence a ballistic
  resistant steel designed to protect against
  airborne projectile armaments and explosive
  devices. The steel is quenched hardenable and is
  ideal for use in the construction of security and
  military vehicles.
• High Yield Steel
• A range of super strong steels which can offer a
  minimum yield strength of up to 1300 MPa, high
  yield steels are used in heavy transporters and
  lifting equipment. The steel can be used
  effectively to reduce build costs as less
  material can be used without the need to
  compromise on quality and performance.

• Weathering Steels
• Products like Cor-ten are structural weather
  resistant steels which are a copper chromium
  alloy designed to be used in load bearing
  applications. The appeal of this still is that
  is self protects by forming its own protective
  layer of rust (patina) which is self
  replenishing. The material requires no treatment
  unless submerged in water for any length of time.
• High strength low alloy steel offer buyers the
  opportunity to review construction projects which
  may well have been 'over engineered' and specify
  a higher strength material which can perform
  exactly the same job but in a smaller thickness.
  Ultimately, this can save considerable cost when
  compared to thicker and less performing material.
