EN S275J0C High Manganese, Structural, Hot Rolled, Quality Steel Product Information -:- For detailed product information, please contact sales. -: # **Product Name:** EN S275J0C Structural Steel for Cold Forming, Hot Rolled, Quality Grade **Overview:** EN S275J0C is a **specialized non-alloy structural steel** defined under the EN 10025-2 standard, belonging to the S275 strength category. This grade is engineered for a dual purpose: it provides **guaranteed impact toughness at 0°C (J0 quality)** while also featuring a **chemical composition optimized for superior cold formability (C designation)**. It is the ideal material for fabricating complex components through processes like press-braking, roll-forming, or stamping, where the finished part must also perform reliably in environments with temperatures at or near freezing. It is **not a "High Manganese" steel**; its premium is derived from its enhanced formability and toughness, not an elevated manganese content. **Key International Standards:** * **Primary Standard:** **EN 10025-2:2019** - Hot rolled products of structural steels - Part 2: Technical delivery conditions for non-alloy structural steels. * **Grade & Designation Decoding:** **S275J0C** * **S:** Structural Steel. * **275:** Minimum yield strength in MPa (for nominal thickness ≤ 16mm). * **J0:** Quality designation, guaranteeing impact energy at **0°C**. * **C:** **Crucial supplementary designation** for **steels intended for cold forming**. This mandates stricter chemical composition limits. * **Core Concept:** This is a **fabrication-oriented, dual-qualified steel**. It is not simply S275J0; the "C" requires tighter controls on phosphorus and sulphur, making it specifically suitable for aggressive cold working without cracking. * **Clarification on "High Manganese":** This is **incorrect**. The manganese content is standard for the S275 class. The defining features are **guaranteed 0°C toughness and certified cold formability**. * **Equivalents:** No direct global equivalent exists for the specific EN "C" classification. The closest comparison would be a **cold-forming grade of ASTM A572 Grade 40 with supplemental Charpy V-notch requirements at 32°F (0°C)**. **Chemical Composition (Ladle Analysis, % by weight, maximum values per EN 10025-2 for 'C' grades):** Chemistry is tailored for ductility and toughness. * **Carbon (C):** ≤ **0.20%** (Often at the lower end of the S275 range to aid both formability and weldability). * **Manganese (Mn):** ≤ **1.50%** (Standard for S275, not elevated). * **Phosphorus (P):** ≤ **0.030%** (**Key Differentiator** - Tighter than the 0.035% limit for standard S275J0. Reduces cold shortness). * **Sulphur (S):** ≤ **0.030%** (**Key Differentiator** - Tighter than the 0.035% limit for standard S275J0. Improves edge ductility and surface quality for forming). * **Nitrogen (N):** ≤ **0.018%**. * **Carbon Equivalent (CEV):** Typically slightly lower than standard S275J0, beneficial for welding formed components. **Physical & Mechanical Properties (for hot-rolled condition, thickness ≤ 16mm):** * **Yield Strength (ReH):** ≥ **275 MPa** (Minimum for t ≤ 16mm; decreases with thickness). * **Tensile Strength (Rm):** **410 - 560 MPa**. * **Elongation at Break (A5):** ≥ **22%** (Minimum, typically good due to favorable "C" grade chemistry). * **Impact Energy (KV):** **≥ 27 J at 0°C** (Longitudinal, Charpy V-notch). * **Cold Formability:** **Excellent.** The primary feature. Certified to withstand severe cold deformation (tight-radius bending, deep drawing, roll-forming) with a **significantly reduced risk of cracking** compared to the standard S275J0 grade. * **Density:** **~7.85 g/cm³**. * **Modulus of Elasticity:** **210 GPa**. **Product Features:** 1. **Superior Cold Formability (Primary Feature):** The "C" chemistry ensures the material can be extensively cold-worked into complex shapes without failure, reducing scrap rates and enabling more sophisticated designs. 2. **Guaranteed Low-Temperature Toughness:** The **J0** quality provides reliable impact resistance for components that will serve in outdoor or cold storage environments (down to 0°C). 3. **Good Weldability:** Maintains good weldability. Pre-heating recommendations should be followed for thicker sections, especially after cold working which can induce residual stresses. 4. **Optimal for Fabrication Sequences:** Perfect for applications where the manufacturing process is: **Cut → Cold Form → Weld Assembly**. **Typical Applications:** S275J0C is specified for cold-formed components that require higher strength than S235 and must endure cold climates. * **Commercial Vehicle & Trailer Manufacturing:** **Cold-formed structural brackets, chassis cross-members, and body reinforcements** for trucks and trailers operating in temperate climates. * **Construction & Architecture:** **Cold-rolled profiles for purlins, girts, and structural frames** in unheated warehouses or buildings in colder regions. * **Material Handling Equipment:** **Heavy-duty racking components, conveyor frames, and forklift parts** that are formed and used in cold storage facilities. * **Agricultural Machinery:** **Formed structural parts and guards** for equipment used in spring/autumn conditions. * **General Heavy Fabrication:** Any component requiring **both a high-strength cold-formed shape and certified 0°C impact toughness**. **Available Forms & Processing:** * **Forms:** Most commonly supplied as **hot-rolled sheet and strip** (in coils or cut lengths), and **plates**. Also available as flat bar. * **Surface:** Often supplied as **pickled and oiled (PO)** to remove mill scale, which is critical for optimal cold forming performance, tool life, and surface finish. * **Processing:** **Exceptionally suited for press-brake bending, roll-forming, and stamping.** Standard cutting and welding methods apply. --- **Critical Procurement Note:** * **Must Specify "C":** It is imperative to specify the full designation **"S275J0C"**. An order for "S275J0" will result in standard material, which is more prone to cracking during aggressive forming. * **Temperature Limit:** The J0 quality is valid for **0°C**. For service temperatures consistently below -10°C, a grade with J2 quality (e.g., **S275J2C**) should be considered. * **Thickness-Strength Relationship:** Mechanical properties are thickness-dependent. Confirm the applicable minimum yield strength for the ordered thickness. * **Not "High Manganese":** This term is erroneous. The correct description is **"Cold-Formable Quality Structural Steel with 0°C Toughness."** * **Design Advantage:** Allows designers to utilize the higher strength of S275 in complex cold-formed sections, enabling weight savings or performance gains over S235J2C. -:- For detailed product information, please contact sales. -: EN S275J0C High Manganese, Structural, Hot Rolled, Quality Steel Specification Dimensions Size： Diameter 20-1000 mm Length <5822 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. -: EN S275J0C High Manganese, Structural, Hot Rolled, Quality Steel Properties -:- For detailed product information, please contact sales. -:
