• 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.
• High Strength Low Alloy Steel 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 High Strength Low Alloy Steel
• Abrasion Resistant Steel
• Used throughout the mining and earth moving
  industry, abrasion resistant steel is engineered
  specifically to last. The material is
  martensitic 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 harden able 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 Cur-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.
