Analisa Kegagalan Sambungan Las Pada Pipa Aunstenit Stainless Steel

Austenit stainless steel pipe which is connected through welding process is easily broken. It is manly due to the crack which is located in HAZ (head effected zone). The changing in micro structure creates that crack sin re there are a lot of martensit pieces. This layer includes cause of residual stress that can cause micro crack. Another cause of this crack is corrosion. This SCC is caused by the residual sterss on the material and it occurs in corrosion environment. These to causes will lead failure in construction. This failure will occur if the value of resistance intensity factor ( k1 > k 1c) or the legth of allowed crack.
