ASTM SA-36 is the most commonly used mild and hot-rolled steel. It has excellent welding properties and is suitable for grinding, punching, tapping, drilling, and machining processes. The yield strength of ASTM SA36 is less than that of cold roll C1018, thus enabling ASTM SA36 to bend more readily than C1018. Normally, larger diameters in ASTM SA36 are not produced since C1018 hot roll rounds are used
