EN 1.0596 High Manganese, Structural, Hot Rolled, Quality Steel Product Information -:- For detailed product information, please contact sales. -: **Product Name:** EN 1.0596 (S355NL / S355ML) Structural Steel, Hot Rolled **Overview:** EN 1.0596 represents a **superior quality, high-manganese structural steel** specifically engineered for **critical applications in low-temperature and highly stressed environments**. As a **fine-grained normalized (NL) or thermomechanically rolled (ML) steel**, it offers enhanced toughness and consistent mechanical properties through its thickness. This steel belongs to the S355 strength class but surpasses standard qualities (JR, J0, J2) by meeting stricter requirements for chemical composition, grain size, and impact toughness. It is a prime choice for welded structures where safety, reliability, and resistance to brittle fracture are paramount. **Key International Standards:** * **Primary Standard:** **EN 10025-3:2019** - Hot rolled products of structural steels - Part 3: Technical delivery conditions for normalized/normalized rolled weldable fine grain structural steels. OR **EN 10025-4:2019** - ... Part 4: Technical delivery conditions for thermomechanical rolled weldable fine grain structural steels. * **Grade Designation:** The material number 1.0596 corresponds to steel grade **S355**. It must be specified with its **delivery condition and subgrade**: * **S355NL:** Normalized or normalized rolled. * **S355ML:** Thermomechanically rolled. * **Impact Test Temperature:** The "L" suffix indicates it is intended for **low-temperature service**, with impact testing required at **-50°C**. * **Equivalents & Comparisons:** * **ASTM:** A709 Grade 50T (for low-temperature applications). * **JIS:** SMA490BW (weathering steel equivalent in toughness class). * **GB/T:** Q355E (impact tested at -40°C, similar application intent). * **ISO:** ISO 630-2:2021, Grade E355. * **Specialized:** Often compliant with **EN 10225** for offshore structures. **Chemical Composition (Ladle Analysis, % by weight, typical maximum values):** Tight controls ensure weldability and toughness. * **Carbon (C):** ≤ **0.18%** (Strictly limited for low-temperature toughness and weldability). * **Manganese (Mn):** ≤ **1.60%** (High for strength; ratio to C is carefully balanced). * **Phosphorus (P):** ≤ **0.025%** (Very low for improved toughness). * **Sulphur (S):** ≤ **0.020%** (Very low for improved through-thickness properties and weldability). * **Silicon (Si):** ≤ **0.50%**. * **Nitrogen (N):** ≤ **0.015%** (Tight control). * **Aluminum (Alt):** ≥ **0.020%** (Mandatory for grain refinement as a killing element). * **Niobium (Nb), Vanadium (V), Titanium (Ti):** May be added individually or in combination in controlled microalloying amounts (e.g., Nb ≤ 0.05%, V ≤ 0.10%, Ti ≤ 0.03%) to promote fine grain and precipitation strengthening. * **Carbon Equivalent (CEV):** Typically **0.36 - 0.42%**, optimized for excellent weldability even in thick sections and restrained joints. **Physical & Mechanical Properties (Normalized condition, thickness ≤ 16 mm example):** * **Yield Strength (ReH):** ≥ **355 MPa** (Thickness-dependent; e.g., ≥ 345 MPa for t > 40mm ≤ 63mm). * **Tensile Strength (Rm):** **470 - 630 MPa**. * **Elongation at Break (A5):** ≥ **22%**. * **Impact Energy (KV):** * **Longitudinal:** **≥ 27 J at -50°C** (Minimum requirement for subgrade NL/ML). Actual values are often significantly higher (e.g., 50-100J). * **Yield-to-Tensile Ratio:** ≤ **0.90** (Ensures good plastic deformation capacity, important for seismic design). * **Fine Grain Size:** Minimum grain size requirement of **ASTM No. 6** or finer (as per EN ISO 643), ensuring microstructure homogeneity. * **Through-Thickness Properties:** Significantly improved due to low sulphur content; specific **Z-direction requirements** (EN 10164, e.g., Z25, Z35) can be specified for highly constrained welds. **Product Features:** 1. **Exceptional Low-Temperature Toughness:** The primary defining feature. Guaranteed impact resistance at **-50°C** makes it suitable for arctic, cryogenic, and winter construction applications. 2. **Fine-Grain Homogeneous Microstructure:** Achieved through microalloying, controlled rolling, and normalizing, resulting in superior and consistent mechanical properties in all directions. 3. **Excellent Weldability (with Procedure):** The low carbon equivalent and clean chemistry minimize the risk of hydrogen-induced cold cracking. However, due to its application in critical environments, welding must follow strictly qualified procedures (often per EN ISO 15614). 4. **High Structural Integrity:** Mandatory fine-grain practice and stringent non-destructive testing requirements (often including ultrasonic testing of plates) ensure high internal quality. **Typical Applications:** EN 1.0596 (S355NL/ML) is specified for the most demanding structural projects: * **Offshore & Maritime:** Primary structures for **fixed offshore platforms (jackets, decks)**, **LNG carrier containment support systems**, and **ice-class vessel hulls**. * **Cryogenic & Low-Temperature Plants:** **Support structures, piping, and storage tank skirts** for LNG terminals, air separation units, and petrochemical plants in cold regions. * **Critical Bridge Construction:** **Heavy welded box girders, expansion joints, and components** in bridges exposed to severe winter climates. * **Power Generation:** **Penstocks, spiral casings for hydropower**, and critical supports in nuclear facilities. * **Heavy Mining & Lifting Equipment:** Critical components for equipment operating in Arctic conditions. **Available Forms & Quality Supplements:** * **Forms:** Primarily **heavy and extra-heavy plates** (thickness up to 120mm+ for normalized grades), also available as sections. * **Delivery Condition:** **Normalized (N/NL)** or **Thermomechanically Rolled (M/ML)** as specified. * **Mandatory Testing:** Extensive, including tensile, impact at **-50°C**, chemical analysis, and grain size determination. **Ultrasonic Testing (UT)** per EN 10160 is typically standard. * **Common Supplementary Requirements:** Through-thickness testing (Z-quality), specific heat treatments, Charpy curves over a temperature range, increased minimum impact energy. --- **Critical Procurement Note:** EN 1.0596 is a **specialized, high-performance steel**. Orders must explicitly state the **full designation (e.g., S355NL)** and reference **EN 10025-3 or -4**. The guaranteed mechanical properties are strictly thickness-dependent. This material is always supplied with a comprehensive **Inspection Certificate 3.1 or 3.2 per EN 10204**, including all test results. It is not a commodity product and requires close technical collaboration with the steel producer for optimal application. -:- For detailed product information, please contact sales. -: EN 1.0596 High Manganese, Structural, Hot Rolled, Quality Steel Specification Dimensions Size： Diameter 20-1000 mm Length <5803 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 1.0596 High Manganese, Structural, Hot Rolled, Quality Steel Properties -:- For detailed product information, please contact sales. -:
