Description
This steel is a general purpose free machining version of 420 stainless, a heat treatable chromium steel. 1.4028 displays the best corrosion resistance in hardened and slightly tempered (around 150oC) condition. A smoothed (industrially polished) and residue-free surface is necessary in order to achieve optimum resistance of this chromium steel grade.

Applications
Dental and surgical instruments, cutlery, pump shafts, gears pinions and cams, steel balls, and various hand tools. Not recommended for vessels containing high pressure gases or liquids or for plastic molds where high surface finishes are required.

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103x N/mm2]: 215, 205 (200oC), 190 (400oC)
Density [g/cm3]: 7.73
Thermal conductivity [W/m.K]: 30.0
Electric resistivity [Ohm mm2/m]: 0.65
Specific heat capacity[J/g.K]: 0.46
Magnetisable: Yes

Soft Annealing
Heat to 745-820oC, cool slowly in air. This will produce a maximum Brinell hardness of 225. Structure is ferrite with spherical carbides.

Hardening
Harden from a temperature of 950-1050oC followed by oil or air quenching. Hardness after quenching is 52-58 HRC.

Tempering
Tempering temperature: 625-724oC, Structure is transformation structure with ferrite.

Mechanical properties at at ambient temperature
Condition: Annealed, quenched and tempered at 850oC, diameter d<=160 mm
0.2% Proof Stress: 650 N/mm2
Tensile strength: 850-100 N/mm2
Elongation (A5): 10% (Longit.)

Tempering Diagram

Forging
Hot forming temperature: 1100-800oC, slow cooling.

Machinability
Good machining characteristics due to the addition of sulfur. High speeds and feeds combined with short brittle chips.

Corrosion Resistance
1.4028 is resistant to the atmosphere, fresh water, dilute acids and alkalis and fruit and vegetable juices.

Welding
Not commonly welded due to its air hardening characteristics. Welding may be performed after preheating to 149-204oC with post weld tempering at temperature for 2 hours . Filler metal should be AWS E/ER420.
