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. In electrical and electronic industry for bimetal themometers, temperature regulators, ceramic-metallic bonds. It is readily machinable due to a higher sulphur content. 

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 200 
Density [g/cm3]: 7.8
Thermal conductivity [W/m.K]: 26.1 
Electric resistivity [Ohm mm2/m]: 0.60
Specific heat capacity[J/g.K]: 0.46

Coefficient of Linear Thermal Expansion 10-6 oC-1

20-100oC 20-315oC 20-538oC
10.4 11.0 11.4

Soft Annealing
Heat to 670-760oC, cool slowly in air.

Hardening
This alloy does not respond to heat treatment.

Forging
Hot forming temperature: 1100-850oC. 

Machinability
Excellent chip breakage due to the addition of sulfur. Good speeds and feeds are possible with this alloy. 
Corrosion Resistance 
Resistant to gas and oil, atmosphere, fresh water , nitric acid and many organic compounds.

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.

Cold working 
This alloy will only withstand moderate cold forming.
