SAE8620H Alloy Round Bar SAE 8620 Alloy Steel Round Bar | UNS G86200 Bar SAE8620H Alloy Solid Round Bar
SAE 8620 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.
HR 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. MittelCompany stocks many diameters of 8620 hot rolled steel to meet the markets demand. We also supply 8620 steel bar to various industries like aerospace, agriculture, ATV, construction, and motorcycle.
Features
1. 1 Good machinability performance
2. 2. Good Cold strain plasticity
3. 3. Good weldability
4. 4. High hardenability
