HSLA steel is a type of alloy steel that provides better mechanical properties and greater resistance to corrosion than carbon steel. It has high yield strength, is ductile and machinable, light in weight, and has high corrosion resistance. HSLA steel is used in automobiles, trucks, bridges, and other structures that experience high stress due to its ability to handle large amounts of stress while being 20-30% lighter than carbon steel of the same strength. Small amounts of elements like manganese, copper, and niobium are added to HSLA steel for strengthening purposes.

1. HSLA STEEL
High Strength Low Alloy Steel

2. What are HSLA steels
• It is nothing but High Strength Low Alloy
Steels
• Also known as micro alloyed steels
PURPOSE: Weight reduction through increased
strength.
• About 0.20% Cu is added for Improve
Corrosion resistance

3. • High-strength low-alloy (HSLA) steel is a type of
alloy steel that provides better mechanical properties
and greater resistance to corrosion than carbon steel.
• HSLA steels vary from other steels in that they not
meet a specific chemical composition, but rather to
specific mechanical properties.

4. CHARACTERISTICS OF HSLA STEELS
• High yield strength
• Can be welded without becoming brittle
(Ductile also)
• Light weight
• High corrosion resistance
• They are ductile and machinable.

5. USES
• They are used in cars, trucks, cranes, bridges,
roller coasters and other structures that are
designed to handle large amounts of stress
areas
• HSLA steels are usually 20 to 30% lighter than
a carbon steel with the same strength.

6. HSLA STEEL----
- In Long Pipe Lines

7. ALLOYING ELEMENTS
• They have a carbon content between 0.05–0.25%
to retain formability and weldability.
• Other alloying elements include up to 2.0%
manganese and small quantities of copper, nickel,
niobium, nitrogen, vanadium, chromium, are added
for strengthening purposes.
