Introduction
Austenitic stainless steels have been widely used in conventional and nuclear power plants for different applications such as superheaters and heater components; they are also developed for use in cryogenics. These steels also perform well at elevated temperatures and they are extensively used for steam pipes and exhaust systems.
The resistance to elevated temperature, oxidation, and corrosion makes the stainless steel a choice for storage tanks. However, there are many difficulties in joining of this material using the fusion welding methods. A concern, when welding the austenitic stainless steels, is the susceptibility to solidification and liquation cracking. Copper does not form brittle intermetallic compounds with iron and the melting point of the copper is lower than Fe and Ni. Thus, the flow-ability increases at higher temperature and encourage a suitable contact between the faying surfaces.

In many instances the formation of brittle intermetallic phases in the diffusion zone leads to unfavorable changes in the mechanical and physical properties of the bonds. The present research focuses on the transient liquid phase diffusion bonding of stainless steel 304 using copper interlayers. The bonding variables and their effect on microstructural changes and mechanical properties of the joints have been investigated using optical and scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS) elemental analyses.

304 contains18% chromium and8% nickel. 316 contains16% chromium,10% nickel and2% molybdenum. The "moly" is added to help resist corrosion to chlorides (like sea water and de-icing salts).

304 stainless steel is STANDARD GRADE and typically comprises 17-20% 8-13% fasteners manufactured from this material show excellent resistence to corrosion in all but the harshest environments. 316 grade stainless steel, also known as MARINE or A4 grade, comprises 16-18.5% 10-14% nickel but also includes 2-3% of the element Molybdenum, which provides increased resistance to chloride corrosion (e.g. corrosion in salt water environments). Molybdenum also minimises metallic contamination making 316 stainless very suitable for food and pharmaceutical processing environments. 316 fasteners are commonly used on boats, and in any coastal environment where the fastener may come into regular contact with salt water spray or mist.
