ASTM A607 Steel, grade 60, hot rolled Product Information -:- For detailed product information, please contact sales. -: ## **Product Datasheet: ASTM A607 Grade 60 Hot-Rolled Steel Sheet & Strip** **Product Overview** ASTM A607 Grade 60 is a **high-strength, low-alloy (HSLA) hot-rolled steel sheet and strip** that delivers a robust combination of **60 ksi minimum yield strength** and **guaranteed atmospheric corrosion resistance**. As the highest standard strength grade within the hot-rolled A607 series, it provides a significant 20% strength advantage over the common Grade 50, making it suitable for highly loaded structural components in exposed environments. Through a precise balance of carbon-manganese chemistry and microalloying (columbium or vanadium), coupled with a mandatory copper content, this grade is engineered for durability and performance in demanding outdoor applications where weight reduction or higher design stresses are critical. It is supplied in the standard hot-rolled condition, offering an economical high-strength weathering solution. **Key International Standards** * **Primary Standard:** **ASTM A607** - Standard Specification for Steel, Sheet and Strip, High-Strength, Low-Alloy, Columbium or Vanadium, or Both, Hot-Rolled and Cold-Rolled. * **Governing Specification:** This product conforms to all requirements for **Grade 60** in the **hot-rolled** condition. * **Type Classification:** **Type 1 (Columbium)** or **Type 2 (Vanadium)**. Specifies the primary microalloying element for grain refinement and precipitation strengthening. * **Corrosion Resistance:** Contains a **mandatory minimum copper content of 0.20%**, providing approximately **twice the atmospheric corrosion resistance** of plain carbon steel. This is a defining, non-optional feature of the A607 specification. * **Material Condition:** Supplied in the **hot-rolled** condition, typically with a mill scale surface. Available as **HRPO (Hot Rolled, Pickled and Oiled)** for applications requiring a clean, paintable surface. **Chemical Composition (Weight % - ASTM A607 Grade 60 Requirements)** Chemistry is optimized for high strength while maintaining adequate weldability and formability. | Element | Requirement (Max, unless noted) | Purpose & Note | | :--- | :--- | :--- | | **Carbon (C)** | 0.26% | Provides base strength; at the upper limit for good weldability. | | **Manganese (Mn)** | 1.35% | Key element for solid solution strengthening. | | **Phosphorus (P)** | 0.04% | Impurity control. | | **Sulfur (S)** | 0.05% | Impurity control. | | **Silicon (Si)** | 0.30% | Deoxidizer. | | **Copper (Cu)** | **0.20% min** | **Mandatory** for atmospheric corrosion resistance. | | **Columbium (Cb/Nb)** | 0.05% Max (Type 1) | Grain refiner for Type 1. | | **Vanadium (V)** | 0.15% Max (Type 2) | Precipitation strengthener for Type 2. | | **Carbon Equivalent (C.E. IIW)** | -- | Typically 0.42 - 0.50. Weldability requires **strict procedure control**. | **Physical & Mechanical Properties** | Property | Requirement (ASTM A607 Grade 60) | Characteristics & Performance Notes | | :--- | :--- | :--- | | **Yield Strength (Min)** | 60 ksi (415 MPa) | Typically 63 - 73 ksi (435 - 503 MPa). | | **Tensile Strength** | 75 ksi (515 MPa) min | Typically 80 - 90 ksi (552 - 621 MPa). | | **Elongation in 2" (Min)** | 17% | Maintains adequate ductility for structural performance. | | **Surface Finish** | Standard **hot-rolled mill scale**. | Characteristic oxide layer; must be removed for painting unless HRPO is specified. | | **Dimensional Tolerance** | Conforms to **ASTM A568** for hot-rolled sheet. | Standard commercial tolerances apply. | | **Atmospheric Corrosion Resistance** | ~2x that of plain carbon steel. | Integral weathering property; base metal forms a protective patina. | | **Key Feature** | **High-Strength Hot-Rolled Weathering Steel:** Provides the maximum yield strength (60 ksi) available in the standard A607 hot-rolled series, offering a cost-effective, durable material for the most demanding exposed structural applications. | **Product Applications** ASTM A607 Grade 60 hot-rolled sheet is specified for critical structural components that face both high mechanical loads and corrosive atmospheric exposure. * **Heavy Equipment & Machinery:** Main structural frames, boom components, high-stress brackets, and reinforced panels for excavators, cranes, and mining equipment. * **Transportation:** Chassis rails and crossmembers for severe-service trucks, dump body floors, trailer main beams, and structural elements for railcars. * **Construction & Infrastructure:** Heavily loaded building panels, long-span roof decking, bridge approach plates, and structural members in aggressive industrial environments. * **Material Handling:** High-capacity storage rack uprights and beams, conveyor structural supports, and heavy-duty container components. * **Energy & Utility:** Structural supports, equipment skids, and access platforms for outdoor power generation and utility installations. **Advantages & Fabrication Notes** * **Controlled Weldability:** Welding requires careful planning and qualified procedures due to the higher carbon equivalent. * **Preheat:** **Generally required.** AWS D1.1 provides guidelines; a typical range is **200-350°F (93-177°C)** depending on thickness and restraint. * **Low-Hydrogen Practice:** Mandatory. Use of matching-strength, low-hydrogen electrodes (e.g., E80XX, E90XX series). * **Procedure Qualification:** Welding Procedure Specifications (WPS) should be qualified per applicable codes (AWS D1.1, D1.5). * **Moderate Formability:** Suitable for **straight-line bending, roll-forming, and punching**. It is less formable than lower-strength grades. Complex shapes may require hot-forming. Generous bend radii are necessary to avoid cracking. * **Corrosion Performance:** The weathering characteristic provides a significant advantage. When painted, damage to the coating results in the formation of a stable patina rather than expansive red rust, offering better long-term integrity. * **Surface Preparation:** For painted applications, **mill scale must be completely removed** via abrasive blasting or by specifying the **HRPO (Pickled and Oiled)** condition to ensure proper coating adhesion and longevity. * **Toughness Consideration:** The base specification does not include impact testing. For dynamic loading, impact, or low-temperature service, **supplementary Charpy V-Notch testing (ASTM A6 S1) must be specified.** **Disclaimer:** This datasheet describes **ASTM A607 Grade 60 Hot-Rolled** sheet and strip. For procurement, specify: **ASTM A607, Grade 60, Type (1 or 2 if relevant), hot-rolled, and surface condition** (as-rolled or HRPO). Reference **ASTM A568** for dimensional tolerances. **Critical Considerations:** 1. **Not a Direct Substitute:** Replacing Grade 50 with Grade 60 requires a complete redesign of members and connections to account for the higher strength and potentially different fabrication requirements. 2. **Welding Expertise:** Fabrication shops must have experience with high-strength steels. Improper welding can lead to hydrogen cracking or inadequate joint strength. 3. **Toughness is Not Guaranteed:** **Impact testing is not standard.** For any structural application, especially under dynamic or impact loads, specifying minimum Charpy toughness values at the service temperature is **strongly recommended, if not mandatory.** 4. **Availability:** Confirm production availability with suppliers, as it may be a specialty item compared to Grade 50. 5. **Comparison to Plate:** For thicker sections, consider **ASTM A588 Grade K** plate, which offers similar 60 ksi weathering performance. This grade is a powerful tool for structural optimization in corrosive environments but demands respect for its fabrication requirements and the explicit need for toughness certification in load-bearing applications. -:- For detailed product information, please contact sales. -: ASTM A607 Steel, grade 60, hot rolled Specification Dimensions Size： Diameter 20-1000 mm Length <4726 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. -: ASTM A607 Steel, grade 60, hot rolled Properties -:- For detailed product information, please contact sales. -:
