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."

# **Product Introduction: TOOLOX® 33 Premium Cold Work Die Steel**
## **1. Overview**
**TOOLOX® 33** is a high-performance, **quenched and tempered, nitrogen-alloyed cold work steel** developed by SSAB, designed to deliver exceptional **strength, toughness, and dimensional stability** directly from the mill. As part of the innovative TOOLOX® family, it is supplied in a **ready-to-use pre-hardened condition** with a guaranteed hardness of **33 HRC**. This steel bridges the gap between conventional pre-hardened mold steels (like P20) and higher-alloy tool steels, offering a unique combination of **high yield strength, excellent impact resistance, and superior machinability** without the need for any post-purchase heat treatment. TOOLOX® 33 is engineered for demanding cold work applications where resistance to chipping, cracking, and plastic deformation under high pressure is critical.

## **7. Processing Guidelines**
* **Machining:** Excellent machinability. Use sharp carbide or coated carbide tools. Standard feeds and speeds for pre-hardened steels (~33 HRC) apply.
* **Electrical Discharge Machining (EDM):** Performs well in EDM. A low-temperature stress relief (e.g., 180°C for 2 hours) after roughing is recommended for ultimate precision work.
* **Welding:** Pre-heat to 100-150°C. Use low-hydrogen electrodes (e.g., OK 48.00 or similar high-toughness filler). Post-weld tempering at 200-250°C is advised for critical applications to relieve stresses.
* **Surface Treatment:** Can be **nitrided** (gas or plasma) to significantly increase surface hardness (up to 1000 HV) and wear resistance without affecting the beneficial core properties.
