Description
This is a free machining version of 430. A basic ferritic, non-heat treatable, 17% chromium stainless with moderate strength and corrosion resistance.

Applications
Not to be used for containing high pressure gas or liquid due to its porosity. Successfully used in a variety of aircraft parts including fasteners, gears, shafts and pinions. PK340 is preferably used for the metal-cutting manufacture of relativelly small parts, such as bolts, nuts, shafts, amd other machine parts, which is not subjcet to any particular corrosion stress, e.g. in water meters, gas meters and switchgear.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [10³ x N/mm²]: 215, 205 (200^oC), 190 (400^oC)
Density [g/cm³]: 7.7
Thermal conductivity [W/m.K]: 25.0
Electric resistivity [Ohm mm²/m]: 0.70
Specific heat capacity[J/g.K]: 0.46

Continuous Cooling Transformation (CCT) Diagram

Time-Temperature Transformation (TTT) Diagram

Soft Annealing
Heat to 750-850^oC, cool slowly in furnace. Structure is ferrite with spherical carbides.

Quenching
Harden from a temperature of 950-1070^oC followed by oil or air (sufficiently fast) quenching.

Tempering
Tempering temperature: 550-650^oC, structure is transformation structure with ferrite.

Mechanical properties at at ambient temperature

Condition: Annealed, diamter d<=60 mm
Tensile strength: max. 700 N/mm²
Hardness: max. 220 HB

Condition: Quenched and tempered at 650^oC, diameter 60<=d<=260 mm
0.2% proof stress: 500 N/mm²
Tensile strength: 650-850 N/mm²
Elongation: 10% (Longit.)

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

Machinability
Excellent chip breakage due to the addition of sulfur. Good speeds and feeds are possible with this alloy.

Welding
Not recommended for welding due to its high sulfur content. If welding is necessary, utilize low heat settings and filler metal of AWS E/ER430 for best results

Corrosion Resistance
Resistant to gas and oil, atmosphere, fresh water , nitric acid and many organic compounds.

Cold working
This alloy will only withstand moderate cold forming.
