S355J2 (1.0577) Low Alloy Steel Bar Bright treatment Q345D

What is the difference between alloy steel and low alloy steel?

Low-alloy steels are the ones which have up to 8% alloying elements whereas high-alloy steels have more than 8% alloying elements. There are around 20 alloying elements that can be added to carbon steel to produce various grades of alloy steel. These provide different types of properties.

Low alloy steels are similar to carbon steels but have additional alloying elements like chromium, molybdenum, etc., to improve their heat treat response. With heat treating, ultimate strengths from about 60 – 300 ksi are possible within this group of materials.
