Detailed description

16Mn Steel: Properties, Standards, Applications and Union Fittings16Mn is a type of **low-alloy high-strength structural steel**. Its core feature is that it enhances strength by adding manganese, while maintaining excellent plasticity and weldability.## I. Core Material Properties of 16Mn1. **Chemical Composition**: The main component is iron (Fe), with manganese (Mn) as the key alloying element, accounting for approximately 1.2%-1.6%. Additionally, it contains a small amount of carbon (C ≤ 0.20%) and no or an extremely small amount of other alloying elements.2. **Mechanical Properties**: The yield strength is about 345MPa (far exceeding the 235MPa of ordinary low-carbon steel), the tensile strength ranges from 470MPa to 630MPa, and it has good low-temperature impact toughness, allowing use in environments as low as -40℃.3. **Implementation Standard**: The current domestic corresponding standard is **GB/T 1591-2018 "Low-Alloy High-Strength Structural Steels"**. In the old standard, the grade corresponding to 16Mn was Q345, and now it is uniformly classified into the Q345 series (e.g., Q345A/B/C/D/E).The following table collates the main chemical composition of 16Mn (corresponding to the Q345 series) based on the standard GB/T 1591-2018 "Low-Alloy High-Strength Structural Steels", clearly indicating the content range and function of each element.
