ASTM A1011 CS Type B ASTM A1011/A1011M Chemical
Carbon, Silicon, Manganese, Phosphorus, Sulfur are called "Five Elements". They are the main impurities in steel. Carbon improves steel hardness. Silicon strengthens the steel strength. Manganese contributes to increase the steel firmness, strength and wear resistance. Phosphorus reduces the steel plasticity and toughness and appearing cold brittleness. Meanwhile, It can significantly increase the strength of steel, and improve the atmospheric corrosion stability. Sulfur makes the hot brittleness of steel high.
