Bethlehem Steel ASTM A572 Grade 65 3/16 to 1/2 in. thick, as-rolled steel plate Product Information -:- For detailed product information, please contact sales. -: **Product Introduction: Bethlehem Steel ASTM A572 Grade 65 Steel Plate (As-Rolled, 3/16" to 1/2" thick)** **Product Overview:** Bethlehem Steel ASTM A572 Grade 65 represents a premium tier of high-strength, low-alloy (HSLA) structural steel plate. Designed for applications where maximum strength-to-weight ratio is paramount, this grade offers a minimum yield strength of 65 ksi. Supplied in the as-rolled condition for thicknesses ranging from 3/16 inches (4.8 mm) to 1/2 inch (12.7 mm), it enables the design of exceptionally strong, yet lightweight structural components and is particularly valued in mobile equipment and transportation industries. **Key International Standard:** * **ASTM A572 / A572M:** Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel. Grade 65 specifies a minimum yield strength of 65 ksi (450 MPa). This is a globally recognized and accepted specification for high-strength structural steel. **Chemical Composition (Typical, weight %):** The composition is precisely balanced to achieve the higher strength level while maintaining adequate weldability and toughness. Micro-alloying with columbium (niobium) and/or vanadium is key to grain refinement and precipitation strengthening. * **Carbon (C):** 0.23% max (Note: Often controlled to the lower end of the range for improved weldability) * **Manganese (Mn):** 1.65% max * **Phosphorus (P):** 0.04% max * **Sulfur (S):** 0.05% max * **Silicon (Si):** 0.40% max * **Columbium (Cb/Nb):** 0.005 - 0.05% * **Vanadium (V):** 0.01 - 0.15% * **Note:** The specific alloy design may vary by producer. Bethlehem Steel historically employed optimized chemistry to reliably meet the demanding mechanical properties in the as-rolled condition for this grade. **Physical & Mechanical Properties (For as-rolled plates 3/16" to 1/2" thick):** * **Yield Strength (min):** 65 ksi (450 MPa) * **Tensile Strength (min):** 80 ksi (550 MPa) * **Elongation in 2" (min):** 17% * **Elongation in 8" (min):** 19% * **Modulus of Elasticity:** ~29,000 ksi (200 GPa) * **Density:** 0.284 lb/in³ (7.85 g/cm³) * **Poisson's Ratio:** 0.29 * **Thermal Expansion Coefficient:** 6.5 x 10⁻⁶/°F (11.7 x 10⁻⁶/°C) * **Machinability:** Fair. The high strength requires more powerful equipment, positive feeds, sharp tooling, and appropriate cutting speeds/feeds. * **Weldability:** Good to Very Good. Welding is readily accomplished using common processes (SMAW, GMAW, FCAW). However, due to the higher strength and carbon equivalent, **strict adherence to proper welding procedures is essential**. This often includes the use of low-hydrogen electrodes, controlled heat input, and may require preheat and interpass temperature control, especially as thickness approaches the upper limit or in highly restrained joints, to prevent hydrogen-induced cracking (HIC) and ensure joint integrity. **Product Applications:** This high-strength plate is specified for critical, weight-sensitive applications where material savings and performance are key drivers: * **Heavy Mobile Equipment & Machinery:** Primary structural members for crane booms, excavator arms, loader frames, and mining shovel components where high strength reduces dead weight and increases payload or operational range. * **Transportation & Trucking:** High-stress members in dump truck bodies, trailer chassis, log haulers, and advanced commercial vehicle frames. * **Access Platforms & Aerial Work Devices:** Booms, jibs, and turntable structures for aerial lifts and telehandlers. * **Material Handling:** Critical components for heavy-duty forklifts, port container handling equipment, and automated storage/retrieval systems. * **Infrastructure:** Specialized bridge components, high-load-capacity sign supports, and energy absorber systems (e.g., for highway safety). * **Military & Defense:** Armor backing plates, vehicle structural elements, and other applications requiring high ballistic or blast resistance in a lightweight configuration. **Additional Information:** * **Condition:** As-rolled. The properties are achieved through controlled thermomechanical processing during rolling, without subsequent heat treatment. * **Availability:** ASTM A572 Grade 65 is a specialized, high-strength product. While Bethlehem Steel was a historic producer, equivalent material is available from select domestic and international mills capable of meeting the stringent requirements of this grade. * **Design Consideration:** The use of Grade 65 steel allows for significant cross-section reduction compared to lower grades (A36, Grade 50), leading to major weight savings. Engineers must carefully consider buckling, fatigue, and connection design specific to high-strength steels. **Disclaimer:** The information provided is based on the ASTM standard and typical industry data for this product.
