| GRADE | THICKNESS (in) |
YIELD STRENGTH (MIN ksi) |
TENSILE STRENGTH (ksi) |
ELONGATION IN 2" 1) (MIN %) |
ELONGATION IN 8" 1) (MIN %) |
|---|---|---|---|---|---|
| A36 | 0.100 - 6.00 | 36 | 58 - 80 | 21 | 18 |
Can be dual certified as A36/CSA G40.21 44W upon request.
1) For plates wider than 24 in., the elongation requirement is reduced two percentage points. Additional elongation requirement adjustments are allowed per the Tension Tests section of Specification ASTM A6.
Tolerances
Tolerances for Mill Plate:
Thickness, width and length tolerances for A36 plates are in accordance with ASTM A6. ASTM A6 Half-Standard Flatness tolerances are available for plate thicknesses of 3/8 inches to 3.0 inches. Inquire for specific mill flatness capabilities.
Tolerances for Temper Leveled Plate:
Thickness, width and length tolerances for A36 plates are in accordance with ASTM A6. ASTM A6 Half-Standard Flatness tolerances or better are available for temper leveled plates. Flatness capabilities are determined by the processing line and the minimum yield strength of the material.
Tolerances for Coils for Conversion To:
For minimum gauge orders, thickness and width tolerances are in accordance with the respective ASTM specifications of A568 for thicknesses of less than 0.230 inches, exclusive, and A635 for thicknesses of 0.230 inches to 1.00 inch, inclusive. Thickness tolerances are in accordance with Table S1.1 found in each of the ASTM specifications of A635 and A568, respective of thickness. Width tolerances are in accordance with Table 6 of ASTM A568 and Table 3 of ASTM A635. Thickness tolerances for nominal gauge orders must be inquired.
All tolerances will be confirmed to the customer via SSAB's Order Acknowledgement document.
