ASTM A570 Steel, grade C, sheet and strip Product Information -:- For detailed product information, please contact sales. -: ## **Product Datasheet: ASTM A570 Grade C Steel Sheet and Strip** **Product Overview** ASTM A570 Grade C is a **structural quality, mild to medium-strength carbon steel sheet and strip** designated for applications requiring a guaranteed **minimum yield strength of 50 ksi (345 MPa)**. As a step up from Grade B (40 ksi yield), it provides a higher load-bearing capacity while maintaining good weldability and moderate formability. This grade is specified primarily based on its mechanical properties and is widely used in a variety of fabricated products where weight savings and structural integrity are important considerations. It is typically supplied in the **hot-rolled** condition and serves as a cost-effective material for general structural fabrication. **Key International Standards** * **Primary Standard:** **ASTM A570 / A570M** - Standard Specification for Steel, Sheet and Strip, Carbon, Structural, Hot-Rolled. * **Governing Specification:** This product conforms to the requirements for **Grade C** as defined in ASTM A570. * **Quality Designation:** **Structural Quality (SQ)**. Suitable for parts subjected to structural loads where bending, moderate forming, and welding are primary fabrication methods. * **Material Condition:** Typically supplied in the **hot-rolled** condition. It is commonly available as **HRPO (Hot Rolled, Pickled and Oiled)** for improved surface quality, paintability, and subsequent processing. * **Related Standards:** Serves a similar market role as **SAE J403 1020** series steels and is a domestic equivalent to international grades like **EN 10025-2 S275JR** in terms of application. It is distinct from High-Strength Low-Alloy (HSLA) grades, achieving its strength through carbon-manganese chemistry rather than microalloying. **Chemical Composition (Weight % - Typical Ranges, Not Mandated)** *ASTM A570 is a mechanical property specification; chemistry is controlled by the producer to meet the tensile and yield requirements but is not a basis for acceptance.* | Element | Typical Range for Grade C (Producer's Aim) | Note | | :--- | :--- | :--- | | **Carbon (C)** | 0.08 - 0.20% | Higher than Grade B to achieve increased strength. | | **Manganese (Mn)** | 0.60 - 0.90% | Elevated to provide solid solution strengthening. | | **Phosphorus (P)** | ≤ 0.035% | Standard limit. | | **Sulfur (S)** | ≤ 0.035% | Standard limit. | | **Silicon (Si)** | ≤ 0.30% | -- | | **Carbon Equivalent (C.E. IIW)** | Typically 0.30 - 0.40 | Good weldability, but requires more care than Grade B. | **Physical & Mechanical Properties (Guaranteed Minimums)** | Property | Requirement (ASTM A570 Grade C) | Typical Performance / Notes | | :--- | :--- | :--- | | **Yield Strength (Min)** | 50 ksi (345 MPa) | Typically 50 - 60 ksi (345 - 414 MPa) | | **Tensile Strength** | 55 ksi (380 MPa) min | Typically 60 - 70 ksi (414 - 483 MPa) | | **Elongation in 2" (Min)** | 21% (for thickness ≤ 0.229") | Adequate ductility for moderate forming. | | **Modulus of Elasticity** | ~29,000 ksi (200 GPa) | Standard for carbon steel. | | **Hardness (Approx., HRB)** | -- | Typically 75-85 HRB. | | **Key Feature** | **Economical 50 ksi Yield Strength Steel:** Provides a guaranteed 50 ksi minimum yield point at a lower cost than HSLA grades, offering a straightforward solution for structural parts requiring higher strength than Grade B but not the enhanced properties of alloyed steels. | **Product Applications** ASTM A570 Grade C sheet and strip are specified for structural components across a broad industrial spectrum. * **General Fabrication & Industrial Equipment:** Heavy-duty frames, bases, platforms, guards, and machinery housings. * **Building & Construction:** Structural members for light buildings, roof purlins, floor decking, and door/window frames. * **Transportation:** Truck and trailer chassis components, container parts, railcar side sheets, and heavy-duty vehicle brackets. * **Storage & Racking:** Uprights and beams for medium-duty pallet racking systems. * **Agricultural Equipment:** Implement frames and structural components. **Advantages & Fabrication Notes** * **Good Weldability with Proper Procedures:** The moderate carbon content requires standard low-hydrogen welding practices (e.g., E70XX electrodes). **Preheating (150-250°F / 66-121°C)** is recommended for thicker sections (> 3/8") or highly restrained joints to prevent hydrogen-induced cracking. * **Moderate Formability:** Suitable for **straight-line bending, roll forming, and punching**. It is less formable than Grade B due to its higher strength. For complex or severe forming operations, consider ordering the material in a softer condition (if available) or selecting a more formable grade. * **Cost vs. Performance:** Offers the most economical route to achieve a 50 ksi yield strength in hot-rolled sheet/coil form for general structural applications. * **Surface Condition:** Standard hot-rolled product has mill scale. For painting or galvanizing, **HRPO (Pickled and Oiled)** is strongly recommended to ensure surface cleanliness and coating adhesion. * **Dimensional Tolerances:** Conforms to standard hot-rolled sheet and strip tolerances as defined in **ASTM A568**. * **Limitations:** Not intended for dynamic, impact, or fatigue-critical applications without thorough analysis. **Impact toughness is not a standard requirement**; if required, it must be specified as a supplementary requirement. Not suitable for low-temperature service without verification of properties. **Disclaimer:** This datasheet provides general information on **ASTM A570 Grade C** hot-rolled sheet and strip. For procurement, specify the **standard (A570), grade (C), dimensions, condition (e.g., HR, HRPO), and any special requirements**. This is a **structural quality, property-based steel**. If consistent chemical composition is critical for your process (e.g., automated welding, heat treatment), consider specifying a chemistry-based grade such as **ASTM A1011 HSLAS Grade 50** or a **SAE J403 1020** series steel. Material selection should be validated for the specific service environment and loading conditions. Always consult with the material supplier for the most appropriate grade and processing recommendations for your application. -:- For detailed product information, please contact sales. -: ASTM A570 Steel, grade C, sheet and strip Specification Dimensions Size： Diameter 20-1000 mm Length <4713 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 A570 Steel, grade C, sheet and strip Properties -:- For detailed product information, please contact sales. -:
