Introduction
SA 283
Carbon Steel Plate / Sheet is a widely used low and intermediate tensile
strength carbon steel material specified under the ASME and ASTM standards. It
is primarily intended for structural-quality plates used in general
fabrication, construction, and industrial applications where moderate strength,
good ductility, and excellent weldability are required. Due to its
cost-effectiveness, ease of fabrication, and reliable mechanical properties, SA
283 is commonly used across industries such as construction, infrastructure,
storage tanks, shipbuilding, and general engineering.
SA 283
carbon steel plates and sheets are manufactured in multiple grades, each
offering distinct mechanical properties to suit different load-bearing and
service requirements. The material performs well under normal atmospheric
conditions and is not intended for high-temperature or high-pressure critical
services, making it ideal for non-critical structural and fabrication uses.
Applicable Standards and Specifications
- ASTM / ASME Standard: SA 283 / ASTM A283
- Product Forms: Plates, sheets, coils
(depending on thickness)
- Manufacturing Process: Hot Rolled (HR)
- Heat Treatment: As-rolled (generally supplied
without heat treatment)
SA 283 is
harmonized with ASTM A283, and the material properties are widely accepted for
structural steel applications worldwide.
Available Grades of SA 283 Carbon Steel
SA 283
carbon steel is available in four primary grades based on tensile strength:
- SA 283 Grade A – Lowest tensile strength,
highest ductility
- SA 283 Grade B – Moderate strength with good
formability
- SA 283 Grade C – Most commonly used grade
with balanced strength and ductility
- SA 283 Grade D – Higher tensile strength
among SA 283 grades
Each grade
is selected based on design requirements, loading conditions, and fabrication
needs.

be supplied in cut-to-size, sheared, or flame-cut conditions.
Key Features and Advantages of SA 283 Carbon Steel
- Excellent weldability without
preheating in most cases
- Good formability and
machinability
- Uniform mechanical properties
- Cost-effective alternative to
higher-strength carbon steels
- Suitable for large-scale
fabrication and structural projects
- Good surface finish in
hot-rolled condition
Weldability and Fabrication
SA 283
carbon steel plates and sheets offer excellent weldability using standard
welding processes such as:
- Shielded Metal Arc Welding
(SMAW)
- Gas Metal Arc Welding (GMAW /
MIG)
- Flux-Cored Arc Welding (FCAW)
- Submerged Arc Welding (SAW)
Low hydrogen
electrodes are recommended for thicker sections to avoid hydrogen-induced
cracking. The material can be easily cut, bent, rolled, and formed using
conventional fabrication methods.
Corrosion Resistance
SA 283
carbon steel offers limited corrosion resistance and is best suited for indoor
or non-corrosive environments. For outdoor or humid conditions, surface
protection such as painting, galvanizing, epoxy coating, or cladding is
recommended to enhance service life.
Typical Applications of SA 283 Carbon Steel Plate /
Sheet
Structural Applications
- Building structures
- Bridges and walkways
- Industrial sheds and warehouses
- Platforms and staircases
Industrial and Fabrication Uses
- Storage tanks and silos
- Boilers and low-pressure
vessels (non-critical)
- Base plates and support
structures
- Fabricated steel components
Construction and Infrastructure
- Roofing and cladding sheets
- Frames and beams
- Columns and supports
- Temporary structures
Marine and General Engineering
- Shipbuilding (non-critical
sections)
- Material handling equipment
- General engineering fabrication
Conclusion
SA 283
Carbon Steel Plate / Sheet is a reliable, economical, and versatile material
widely used in structural, construction, and fabrication industries. Its
balanced mechanical properties, excellent weldability, and availability in
multiple grades make it an ideal choice for general-purpose applications where
moderate strength and durability are required. When properly fabricated and
protected against corrosion, SA 283 steel delivers consistent performance and
