A flange—also referred to as a flange plate or rim—is a component used to connect shafts to one another, or, more commonly, to join the ends of pipes. Flanges are also utilized at the inlet and outlet ports of equipment to facilitate connections between two devices—for instance, the flange on a speed reducer. A "flange connection" or "flanged joint" refers to a detachable joint assembly comprising three interconnected elements—a flange, a gasket, and bolts—that together form a sealed structural unit. In the context of piping systems, a "pipe flange" specifically denotes a flange used for plumbing within the installation; when applied to equipment, it refers to the inlet or outlet flange of that specific device. Flanges feature a series of holes through which bolts are inserted to securely fasten the two flanges together, while a gasket placed between the flanges ensures a leak-proof seal. Flanges are broadly categorized into three types: threaded (screw-in) flanges, welded flanges, and clamp-type flanges. Flanges are invariably used in pairs; threaded flanges are suitable for low-pressure piping applications, whereas welded flanges are required for systems operating at pressures exceeding 4 kilograms per square centimeter. A sealing gasket is inserted between the two flange plates, which are then firmly secured using bolts. The thickness of a flange—as well as the specifications of the bolts used to fasten it—vary depending on the specific pressure rating required for the application. When connecting equipment such as water pumps or valves to piping systems, the corresponding connection points on these devices are often manufactured in the shape of a matching flange; this method of attachment is also referred to as a "flange connection." Generally, any connecting component that utilizes bolts to join and seal the perimeters of two flat surfaces—such as the joints in ventilation ducts—is termed a "flange"; such components may collectively be classified as "flange-type parts." However, since such a connection often constitutes merely a *portion* of a larger device—for instance, the interface between a flange and a water pump—it would be inappropriate to classify the entire water pump itself as a "flange-type part." Conversely, smaller components—such as valves—that feature such flanged interfaces may indeed be appropriately categorized as "flange-type parts." -:- For detailed product information, please contact sales. -: Sandvik 13RM19 Strip Steel Flange Product Information -:- For detailed product information, please contact sales. -: Sandvik 13RM19 Strip Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

Sandvik 13RM19 Strip Steel Product Information -:- For detailed product information, please contact sales. -: ## **Sandvik 13RM19 Strip Steel – High-Strength, Corrosion-Resistant Martensitic Stainless Steel for Precision Springs** ### **Product Overview** Sandvik 13RM19 is a **premium martensitic stainless steel strip** specifically engineered for high-performance spring applications that demand an exceptional combination of **strength, corrosion resistance, and consistent fatigue life**. Characterized by its ability to be supplied in a pre-hardened and tempered (aged) condition, 13RM19 offers spring manufacturers a ready-to-form material that eliminates the need for final customer heat treatment, minimizing distortion and ensuring predictable mechanical properties. It is designed to bridge the gap between standard stainless spring steels and more exotic, costly alloys. ### **Key Advantages** * **High Strength-to-Corrosion Ratio:** Delivers significantly higher tensile and fatigue strength than austenitic grades like 302 or 304, while offering better corrosion resistance than hardenable carbon spring steels. * **Excellent Relaxation Resistance:** Maintains load-bearing capability (resists "set") better than many austenitic grades, especially at moderately elevated temperatures. * **Ready-to-Use Condition:** Supplied in the final hardened and tempered state, simplifying production and ensuring dimensional stability of formed springs. * **Good Formability in Hardened State:** Allows for precise bending and coiling operations to create complex flat spring shapes without intermediate annealing. * **Predictable Performance:** Sandvik's controlled processing ensures uniform microstructure and properties coil-to-coil, critical for reliable spring function. ### **Chemical Composition (Typical, wt%)** The composition is a carefully balanced martensitic stainless steel, optimized for hardenability and corrosion resistance. | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | **Carbon (C)** | 0.12 - 0.17 | **Chromium (Cr)** | 12.0 - 14.0 | | **Nickel (Ni)** | 0.40 - 0.80 | **Molybdenum (Mo)** | 0.40 - 0.80 | | **Silicon (Si)** | ≤ 0.50 | **Manganese (Mn)** | ≤ 1.00 | | **Vanadium (V)** | ≤ 0.15 | **Sulfur (S)** | ≤ 0.030 | | **Phosphorus (P)** | ≤ 0.030 | **Iron (Fe)** | Balance | *Note: The addition of Nickel and Molybdenum enhances hardenability, toughness, and corrosion resistance compared to basic martensitic grades.* ### **Physical & Mechanical Properties (Typical, as supplied in H&T condition)** * **Density:** 7.8 g/cm³ * **Modulus of Elasticity (E):** 200 GPa * **Tensile Strength (Rm):** **1800 – 2150 MPa** * **Yield Strength (Rp0.2):** 1650 – 2000 MPa * **Hardness:** 480 – 550 HV / 48 – 52 HRC * **Elongation (A₅₀):** 3 – 6% * **Fatigue Strength:** Excellent, suited for dynamic applications. #### **Temperature Considerations:** * **Maximum Continuous Service Temperature:** **Approx. 250°C (480°F)**. Properties are stable for intermittent or continuous exposure up to this range. * **Low-Temperature Performance:** Maintains good toughness down to cryogenic temperatures. #### **Corrosion Resistance:** * Superior to standard carbon and low-alloy spring steels. * Suitable for applications exposed to atmospheric conditions, moisture, mild chemicals, and some industrial atmospheres. Not recommended for severe chloride environments (e.g., marine splash zone) where austenitic or duplex grades would be preferred. ### **International Standards & Approvals** Sandvik 13RM19 is a proprietary grade that aligns with the general requirements of high-strength martensitic stainless spring steels. * **Sandvik Proprietary Grade:** **13RM19** * **Similar/Related Standards:** * **EN / Werkstoff:** Similar in concept to 1.4421 (X20CrNiMoV12-10) spring variants. * **ASTM:** A313 (for stainless spring wire - Type 631/17-7PH is a different but performance-similar precipitation-hardening grade). * **UNS:** S42000-series modified. * **Industry Use:** Widely specified and approved in automotive, electrical, and precision engineering sectors for critical spring applications. ### **Product Applications** 13RM19 is ideal for demanding flat and formed spring components where reliability, space constraints, and a corrosive service environment intersect. * **Automotive & Transportation:** * Fuel injector springs * Valve springs (e.g., EGR valves) * Clutch and brake system springs * Seat belt retractor components * Sensor and actuator springs * **Electrical & Electronics:** * High-reliability connector springs (e.g., in automotive ECUs, industrial controls) * Spring contacts in switches and relays * Battery contact springs * **Industrial & Hydraulics:** * Spring-loaded seals and packing rings * Pressure relief valve springs * Spool valve springs in pneumatic and hydraulic systems * Agricultural machinery springs * **Consumer & General Engineering:** * High-performance lock springs * Springs in valves and regulators for domestic appliances * Critical snap rings and retaining rings ### **Processing Guidelines** * **Forming:** Can be stamped, blanked, and bent in the supplied hardened condition. Tooling must be robust and designed for high-strength materials. A low-temperature stress relief (e.g., 250-300°C for 30-60 minutes) after severe forming is often recommended to optimize spring performance and stability. * **Machining:** Difficult in the hardened state; grinding or EDM are suitable methods if secondary machining is required. * **Heat Treatment:** **DO NOT re-austenitize or re-harden.** The material is supplied in its final tempered condition. Any exposure above ~400°C will soften the material. * **Surface Treatment:** Accepts common coatings like zinc phosphate, electroplating (zinc, nickel), or organic coatings for enhanced corrosion protection or appearance. ### **Availability** Sandvik supplies 13RM19 as precision cold-rolled strip. * **Thickness:** Typically 0.10 mm to 2.0 mm (custom ranges possible) * **Width:** Up to 330 mm * **Condition:** Hardened and Tempered (H&T), with a clean, bright surface finish. * **Temper:** Spring temper * **Packaging:** Coils or straight lengths, protected against mechanical damage and corrosion. --- **Critical Application Note:** Sandvik 13RM19 is a high-strength engineering material. Successful implementation requires careful design considering its high yield strength and limited elongation in the supplied state. **Consultation with Sandvik's technical service is strongly recommended** to select the correct temper, review forming limitations (minimum bend radii), and validate the design for the specific application's stress, fatigue, and environmental conditions.
