Din 28cr4 Alloy Pipe Fatigue Strength Key Performance - China

Mechanical Properties: High tensile strength and good toughness contribute to fatigue strength.

DIN 28Cr4 alloy pipe boasts a tensile strength of ≥885 MPa, demonstrating high strength.

Furthermore, its impact energy is ≥47 J and its impact toughness is ≥59 J/cm².

This excellent toughness ensures the material maintains integrity under impact loads, resisting fracture and thus improving fatigue performance.

Heat Treatment: Different heat treatment conditions produce different microstructures, which in turn affect fatigue strength.

DIN 28Cr4 alloy pipe is typically used in the quenched and tempered state, but can also be used after normalizing.

Quenching and tempering imparts excellent overall mechanical properties, refines grain size, and improves fatigue strength.

Normalizing also improves the steel's microstructure, contributing to a certain improvement in fatigue strength.

For example, the fatigue strength of lamellar pearlite is significantly lower than that of granular pearlite.

Within granular pearlite, the finer the cementite particles, the higher the fatigue strength.
