What Is SUM41 Steel?
Free machining steel, like SUM41, is enhanced by adding elements such as sulfur, lead, and phosphorus to carbon steel, improving its machinability and workability. The “SUM” acronym stands for steel use machinability.
SUM is divided into 13 types based on chemical composition. Each type is identified with a unique number or letter following the SUM prefix. SUM41, specifically, is a medium carbon free machining steel known for its high machinability and strength, achieved through precise component adjustments, including a higher manganese content to counteract strength reduction from sulfur.
Uses of SUM41 Steel
SUM41 steel’s enhanced machinability makes it ideal for continuous, high-quality processing, leading to improved productivity. Its excellent machining characteristics also reduce wear on cutting tools, thus decreasing running costs. Being a medium carbon steel, SUM41 is particularly effective for parts requiring strength, making it suitable for various applications where both machinability and strength are essential.
