Bethlehem Steel ASTM A573 Grade 58 3/16 to 1/2 in. thick, steel plate Product Information -:- For detailed product information, please contact sales. -: **Product Introduction: Bethlehem Steel ASTM A573 Grade 58 Steel Plate (3/16" to 1/2" thick)** **Product Overview** Bethlehem Steel ASTM A573 Grade 58 is a carbon-silicon structural steel plate distinguished by its **improved toughness** properties. It is part of the A573 specification, which is specifically designed for applications requiring better notch toughness than standard structural grades like A36. Supplied for thicknesses from 3/16" (4.8 mm) to 1/2" (12.7 mm), this plate offers a good balance of strength, notch toughness, and weldability. It is often specified for structural uses where impact resistance at lower temperatures is a consideration, particularly in welded construction. **Key International Standard** * **ASTM A573 / A573M:** *Standard Specification for Structural Carbon Steel Plates of Improved Toughness.* Grade 58 designates a minimum yield strength of 58 ksi (400 MPa). This standard is recognized and utilized internationally for applications where enhanced fracture resistance is required. **Chemical Composition (Typical, weight %)** The composition is controlled to provide a fine-grain practice, which is fundamental to achieving the improved toughness. It is a carbon-manganese-silicon steel. * **Carbon (C):** 0.23% max * **Manganese (Mn):** 0.85 - 1.20% (Note: Tighter range than general structural grades) * **Phosphorus (P):** 0.035% max * **Sulfur (S):** 0.040% max * **Silicon (Si):** 0.15 - 0.40% (Contributes to deoxidation and strength) * **Grain Refinement:** Produced to a fine austenitic grain size practice, typically through the use of aluminum or other grain-refining elements. **Physical & Mechanical Properties (For plates 3/16" to 1/2" thick)** * **Tensile Strength:** 70 - 85 ksi (485 - 585 MPa) * **Yield Strength (min):** 58 ksi (400 MPa) * **Elongation in 2" (min):** 21% * **Elongation in 8" (min):** 23% * **Key Differentiator - Charpy V-Notch Impact Test:** Plates over 0.375" (9.5mm) thick are required to meet impact energy absorption of **15 ft-lbf (20 J)** at a specified test temperature (e.g., 70°F / 21°C or lower as agreed upon). This is a defining feature of A573 steels. * **Modulus of Elasticity:** ~29,000 ksi (200 GPa) * **Density:** 0.284 lb/in³ (7.85 g/cm³) * **Weldability:** Excellent. The combination of moderate carbon content, fine grain structure, and controlled chemistry makes it very suitable for all common welding processes (SMAW, GMAW, FCAW, SAW). Standard preheating practices apply for thicker sections or restrained joints. **Product Applications** ASTM A573 Grade 58 is selected for structural applications where reliability under dynamic or impact loading, or service at cooler temperatures, is a priority over using the highest strength steel. * **Structural Supports:** Critical welded connections, brackets, and supports in buildings and bridges where notch toughness is a design factor. * **Industrial Machinery:** Base plates, frames, and housings for heavy machinery subject to shock or vibration loads. * **Material Handling Equipment:** Components for cranes, hoists, and conveyor systems where impact resistance is beneficial. * **Transportation:** Sub-frames and structural elements in rail cars and heavy trailers. * **General Fabrication:** Where a notch-tough alternative to A36 or A572 Grade 50 is desired without moving to a full-fledged pressure vessel grade like A516. **Additional Information** * **Condition:** Typically supplied as-rolled, but can also be furnished normalized if specified for further enhancement of toughness properties. * **Distinction from A572:** While A572 Grades are HSLA steels strengthened by micro-alloying (Nb/V), A573 is a carbon steel strengthened by chemistry and grain refinement, with the standard's primary focus on improved toughness rather than high strength-to-weight ratio. * **Availability:** Steel meeting ASTM A573 Grade 58 is produced by many plate mills. The Bethlehem Steel brand signifies historical production to this quality standard. **Disclaimer** The information provided is based on the ASTM standard and typical industry data.
