Prime Steel Deformed Bars
ASTM A615 / A615M – Grade 40 & Grade 60 | Fully Compliant with International Standards
Prime Steel Industry has an approximate production capacity of 100,000 MT per year. We are experts in the production of Grade-40 & Grade-60 deformed steel bars qualifying the ASTM A615/A615M standards.
Mechanical Properties (Min Req)
| Grade | Yield Strength | Tensile Strength | Elongation* |
|---|---|---|---|
| 40 | 40,000 PSI (280 MPa) | 60,000 PSI (420 MPa) | Size-dependent (per ASTM A615) |
| 60 | 60,000 PSI (420 MPa) | 90,000 PSI (620 MPa) | Size-dependent (per ASTM A615) |
Stress–Strain Curve (Grade 60)
Quality & Compliance
- Manufacturing precision: Strict tolerances of ±0.5% on diameter.
- Weight tolerance: -5% maximum below nominal (per ASTM A615/A615M).
- Rigorous testing: Every batch undergoes testing for yield, tensile, elongation, and bend tests.
- Standard compliance: Fully complies with ASTM A615/A615M.

Important Technical Notes
- All specifications comply with ASTM A615/A615M international standards.
- Standard bar length is 12 meters (40 feet).
- Dimensions, weights, and mechanical properties are nominal values.
Tolerances
- Weight tolerance: -5% maximum below nominal (per ASTM A615/A615M).
- Dimensions may vary slightly due to normal manufacturing tolerances.
*Elongation requirements vary by bar size (e.g. 7% to 9% for Grade 60, 11% to 12% for Grade 40).
