UNS F34800 Cast Iron Product Information -:- For detailed product information, please contact sales. -: ## **UNS F34800 Cast Iron - Technical Specification** ### **1. Product Overview** **UNS F34800** is a standardized designation in the Unified Numbering System for a **high-performance, alloy-enhanced pearlitic malleable cast iron**. This material represents a premium grade within the malleable iron family, engineered to deliver **exceptional tensile strength (typically 450-550 MPa range), superior wear resistance, and good fatigue properties** through sophisticated alloy design and controlled heat treatment processes. The "F34800" designation specifically identifies a malleable iron formulation that bridges the performance gap between standard pearlitic grades and quenched-and-tempered materials, offering an optimal balance of strength, ductility, and manufacturability. Characterized by its refined microstructure of **tempered martensite or fine pearlite with well-dispersed alloy carbides**, F34800 provides engineers with a material solution that combines **near-steel strength levels with the casting advantages of iron**. This grade is particularly valuable for applications requiring high load-bearing capacity, resistance to abrasive wear, and dimensional stability in complex geometries where forging or machining from billet steel would be economically challenging. ### **2.
