Frequently Asked Questions
Können 100-70-03 ductile iron ersetzen forged steel?
In viele applications, ja. Güte 100-70-03 hat tensile strength comparable zu AISI 1045 forged steel (655 MPa) bei approximately 30-40% unter finished teil kosten due zu near-net-shape casting eliminating extensive machining. However, ductile iron hat unter fatigue strength als forged steel (~35% von tensile vs ~50% für steel), so forged steel ist noch erforderlich für der highest-fatigue applications.
