Bethlehem Steel BETHSTAR Grade 60 1/4 to 1-1/4 in. thick, killed steel plate Product Information -:- For detailed product information, please contact sales. -: ## **Product Datasheet: Bethlehem Steel BETHSTAR® Grade 60 Killed Steel Plate** **Product Overview** Bethlehem Steel BETHSTAR® Grade 60 is a premium high-strength, fine-grained **fully killed** structural steel plate engineered to deliver exceptional strength, toughness, and weldability. As a killed steel, it undergoes thorough deoxidation with silicon and aluminum, resulting in a homogeneous microstructure free from porosity, ensuring superior internal soundness and uniform mechanical properties through thickness. This plate is designed for critical structural applications where higher strength-to-weight ratio and reliable performance under dynamic loading are required. It is commercially available in thicknesses ranging from **1/4 inch (6.4 mm) to 1-1/4 inches (31.8 mm)**. **Key International Standards & Specifications** BETHSTAR® Grade 60 was Bethlehem Steel's proprietary grade formulated to meet or exceed leading international structural steel standards: * **Primary Equivalent:** **ASTM A572 / A572M Grade 60** – High-Strength Low-Alloy Columbium-Vanadium Structural Steel. * **Common Cross-Reference:** **ASTM A529 / A529M Grade 55** (Note: A529 typically caps at 55 ksi yield; BETHSTAR 60 offers higher strength). * **Also Conforms To:** Relevant requirements of **ASTM A6** for structural steel plates, often specified with Supplementary Requirement S1 (Impact Testing). * **Industry Acceptance:** Widely accepted in specifications requiring **American Bureau of Shipping (ABS)** grades or other marine/construction standards calling for 60 ksi yield strength with killed steel practice. **Chemical Composition (Typical, Weight % - Aligned with ASTM A572 Gr 60)** The chemistry is balanced to achieve the target strength through microalloying (Nb, V) while the killed steel practice ensures fine grain size for toughness. | Element | ASTM A572 Gr 60 Requirement (Max, unless noted) | Typical BETHSTAR® Grade 60 Aim / Range | | :--- | :--- | :--- | | **Carbon (C)** | 0.26% | 0.18 - 0.23% | | **Manganese (Mn)** | 1.35% | 1.00 - 1.30% | | **Phosphorus (P)** | 0.04% | ≤ 0.025% | | **Sulfur (S)** | 0.05% | ≤ 0.025% | | **Silicon (Si)** | 0.40% | 0.15 - 0.30% (deoxidizer) | | **Columbium (Cb/Nb)** | 0.05% (V alternative) | 0.005 - 0.040% (primary strengthener) | | **Vanadium (V)** | 0.15% (Cb alternative) | 0.01 - 0.08% (often used with Cb) | | **Aluminum (Al), Total** | (Min. often specified for killed steel) | ≥ 0.015% (key for fine grain practice) | | **Nitrogen (N)** | - | Controlled | | **Carbon Equivalent (C.E. IIW)** | - | Typically 0.40 - 0.45 | **Physical & Mechanical Properties** | Property | Standard Requirement (ASTM A572 Gr 60) | Typical BETHSTAR® Grade 60 Performance | | :--- | :--- | :--- | | **Yield Strength (Min)** | 60 ksi (415 MPa) | 65 - 75 ksi (448 - 517 MPa) | | **Tensile Strength** | 75 ksi (520 MPa) Min | 80 - 90 ksi (552 - 621 MPa) | | **Elongation in 2" (Min)** | 17% | 18 - 22% | | **Modulus of Elasticity** | ~29,000 ksi (200 GPa) | ~29,000 ksi (200 GPa) | | **Density** | 0.284 lb/in³ (7.85 g/cm³) | 0.284 lb/in³ (7.85 g/cm³) | | **Notch Toughness (Typical)** | Not standard, but can be specified per A6 S1 | Excellent Charpy V-Notch values at room and sub-zero temperatures due to killed, fine-grained microstructure. | | **Key Feature** | **High-Strength Killed Steel:** Provides an optimal balance of guaranteed 60 ksi minimum yield, excellent internal soundness, and enhanced impact resistance for demanding service conditions. | | **Product Applications** BETHSTAR® Grade 60 was specified for a wide range of structural and mobile equipment applications requiring higher strength without compromising fabricability: * **Heavy Construction & Bridge Work:** Girders, trusses, bearing plates, and other highly stressed components in bridges and large-span structures. * **Commercial & Industrial Building Construction:** Columns, heavy beams, and base plates in high-rise buildings and industrial plants where load capacity and material efficiency are critical. * **Mobile Crane & Heavy Equipment:** Boom sections, outrigger pads, and main frames for cranes, excavators, and drilling rigs. * **Transportation & Trucking:** Frame rails, fifth wheels, and suspension components for heavy-duty trucks, trailers, and logging equipment. * **Material Handling & Mining:** Chassis for high-capacity forklifts, buckets, and structural members in mining machinery. * **General Fabrication:** As a superior alternative to A36 and A572 Gr 50 in any design where increasing strength allows for weight reduction or improved payload capacity. **Advantages & Fabrication Notes** * **Superior Weldability:** The combination of controlled carbon content, moderate carbon equivalent, and killed steel practice results in excellent weldability with low preheat requirements for most thicknesses. Standard welding procedures for HSLA steels are applicable. * **Enhanced Toughness:** The fine-grained, fully killed microstructure provides reliable notch toughness and resistance to brittle fracture, making it suitable for dynamic or low-temperature service. * **Excellent Formability:** Offers good cold bending and forming characteristics relative to its strength level, suitable for moderate forming operations. * **Uniform Properties:** The killed steel process ensures consistent mechanical and through-thickness properties, reducing variability in fabrication. * **Legacy Product Note:** BETHSTAR® was a branded product line of Bethlehem Steel. Modern direct equivalents are readily available as **ASTM A572 Grade 60 (killed, fine-grained)** from contemporary steel producers. **Disclaimer:** This datasheet describes the historical **Bethlehem Steel BETHSTAR® Grade 60** product based on its typical conformance to industry standards. For current procurement, it is recommended to specify **ASTM A572 Grade 60** with requirements for killed steel practice and fine grain, and source material from active producers who supply certified mill test reports confirming the required chemistry, mechanical properties, and deoxidation practice. -:- For detailed product information, please contact sales. -: Bethlehem Steel BETHSTAR Grade 60 1/4 to 1-1/4 in. thick, killed steel plate Specification Dimensions Size： Diameter 20-1000 mm Length <4659 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: Bethlehem Steel BETHSTAR Grade 60 1/4 to 1-1/4 in. thick, killed steel plate Properties -:- For detailed product information, please contact sales. -:
