摘要（英）：

This object (16) is made of spheroidal graphite cast iron, the steroidal graphite cast iron comprising, in % by weight, the following elements: carbon (C) less than or equal to 3.65% and silicon (Si) between 3.3% and 3.7%. Optionally, the cast iron comprises: phosphorus (P) ≤ 0.1%, and/or manganese (Mn) ≤ 0.6%, and/or chromium (Cr) ≤ 0.2%, and/or titanium (Ti) ≤ 0.15 %, and/or sulfur (S) ≤ 0.05%, and/or magnesium (Mg) between 0.005% inclusive and 0.07% inclusive, and/or copper (Cu) ≤ 0.3%, and/or nickel (Ni) ≤ 0.4%, and/or molybdenum (Mo) ≤ 0.02%, and/or aluminum (Al) ≤ 0.02%, and/or vanadium (V) ≤ 0.04%, the remainder being iron (Fe), and inevitable residual elements at contents of less than 0.01%. The spheroidal graphite cast iron has a carbon equivalent CEQ = C (%) + 1/3 Si (%) + 1/3 P (%) of less than or equal to 4.75%. The spheroidal graphite cast iron has a resilience (E) greater than or equal to 9.49 J. Application to piping components or highway components.
