Forging of 1.4028 Steel

Forging enhances 1.4028 stainless steel’s structural benefits, with temperatures ranging between 1100°C to 800°C, followed by quenching. This process underscores the durability of DIN 1.4028 stainless steel, readying it for rigorous applications.

Heat Treatment of 1.4028 Stainless Steel

  • Soft Annealing

Heat to 745-820°C and allow cooling gradually in the air. This process achieves a maximum Brinell hardness of 225, resulting in a ferritic structure with spherical carbides.

  • Hardening

Harden by heating to a temperature range of 950-1050°C, then quench in oil or air. This process results in a hardness of 52-58 HRC post-quenching.

  • Tempering

Tempering temperature: 625-724°C, resulting in a transformation structure that includes ferrite.

Application of 1.4028 Stainless Steel

Typicall pplications include dental and surgical instruments, cutlery, pump shafts, gears, pinions, cams, steel balls, and assorted hand tools. Not suitable for high-pressure gas or liquid containers, or plastic molds needing high surface finishes.
