3. 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)
4. 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.
5. 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.
