ASTM D3 High carbon steel bars are steels that have been quenched and tempered at high temperatures. This treatment gives it high hardness, good wear resistance, and can withstand the use of high pressure and high temperature conditions. ASTM D3 High carbon steel rods contain high levels of carbon and chromium in their chemical composition, further increasing their strength and corrosion resistance.
