Product Description

1.6523/SAE8620/20CrNiMo Alloy Constructure Steel Round Steel 

Product Introduction
20CrNiMo is one of alloy construture steel according to Chinese Standard. Standard Code: A50202.
The steel round bar is high hardenability, without fragility after tempering,good weldability.Nice machinability and Cold strain plasticity.     

8620 steel bar is a low carbon nickel chromium molybdenum alloy with good carburized properties, formability, and weldability.
This grade is a low-cost steel that is the most widely used carburizing alloy. Due to its nickel content, this grade has a high strength case and core toughness.
The chromium and molybdenum support carburizing, and give good surface hardness and wear.

Features

1. 1 Good machinability performance
2. 2. Good Cold strain plasticity 
3. 3. Good weldability
4. 4. High hardenability
