- High Speed Steel (HSS) is also known as air hardening steel or steel. It is an alloy steel of complex components, including tungsten, molybdenum, chrome, vanadium, cobalt carbide forming elements. Amount of alloying element is approximately up to 10-25%. Under high temperature of about 500℃, High Speed Steel still can keep high hardness of 50HRC above. Red Hardness is the main features of High Speed Steel.

I wanted to know whether the twice more expensive rods (in pack of 5) are different from the rods bundled as pack of 10. It turned out that the seller opened the original package of 10 rods, removed 5 of them, and is selling the remaining 5 for the same price. The rods are fine. One star for business model.

I'm using these to start my engraving journey. I sharpen them on my diamond wheel.

Two of the five in package had gouges and discoloring. Not sure if it's damage or manufacturing flaw. The other three are perfect. Using them to wind custom diameter coils. Cannot slide the coil off with damaged rods, so 2 of 5 not usable. Used Brasso and fine grain sandpaper to clean / polish the good rods.
