Mainly introduce the 50Mn steel in terms of its characteristic, chemical composition, mechanical properties and so on.
Basic information:Name: high quality carbon structural steel Grade: 50MnStandard: GB/T 699-1999
Characteristics:50Mn is with relatively high strength, flexibility and hardness, more used after quenching and tempering, and with poor weldability. 50Mn round steel is used for some heat treatment parts which is with high requirement for the wear resistance under high loading action, such as gear, gear shaft and mandrel cross section is under 80mm,etc. Its mechanical performance is similar to 50#, but with higher hardenability and after heat treatment, the strength, flexibility and hardness are all slightly higher than 50# steel. Poor weldability and have a tendency of overheating sensitivity and temper brittleness, used for stress bearing parts, high wear resistance parts and high stress parts, like mandrel diameter less than 80 mm. After high frequency quenching, it can also be used to manufacture train shaft, worm, connecting rod and automobile crankshaft, such as gear, gear shaft, friction disk, mandrel and flat spring.

Comprehensive Guide to ISO Steel Pipe Standards
Steel pipes are essential components in various industries, from construction and infrastructure to oil and gas. Ensuring their quality, safety, and efficiency is paramount, which is where the International Organization for Standardization (ISO) comes into play. ISO sets globally recognized standards that specify the properties and testing methods for steel pipes, providing a common language for manufacturers, suppliers, and customers. This article delves into the ISO standards for steel pipes, offering a detailed overview of their specifications and applications.
