The problem related to out-gassing is that it can form pinholes in the coating. When exposed to moisture or atmospheric contaminants, these pinholes can be filled with corrosive materials, which can degrade the component. • Austenitic stainless steels are the most common choice for high vacuum and ultra-high vacuum systems. Not all alloys are suitable; e.g. the free-machining 303 steel contains sulfur, which tends to outgas. Alloys with good weldability under argon arc welding are usually chosen. • Mild steel can be used for moderate vacuums above 1×10 torrs (1.3×10 kPa).
