Alloy 16Mn seamless steel tube was originally a type of material in steel. It was a term used for steel in the past. The current term is Q345B seamless steel tube, which represents the carbon content in this type of steel being approximately 0.16%. The Mn is mentioned separately because it has a higher content among the five main elements (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur S), with the manganese content ranging around 1.20-1.60%.

The 16Mn series is a low-alloy steel plate, which is a general material or grade within this series. Upon special requirements, the steel plate can undergo certain specialized treatments: heat treatment and Z-directional properties. Heat treatment includes controlled rolling and normalizing, etc. Z-directional properties include Z15, Z25, and Z35.

Key Features: Excellent overall performance, good low-temperature properties, excellent stamping, welding, and machinability.

Application Examples: Mining, transportation, chemical industry, and various types of machinery.
