EXPERIMENTAL INVESTIGATION OF WELD JOINTS BETWEEN SINTERED NB MODIFIED HK30 STAINLESS STEEL AND WROUGHT/CAST STAINLESS STEELS

Very important property of powder metallurgy parts is ability to join components produced by different manufacturing technologies or dissimilar materials. Properties Nb modified HK30 are highly influenced conditions applied during sintering. Weldability sintered can be improved using favorable sintering conditions. In this regard, effect parameters on fusion weldability presented in paper. Investigation weld joints between HK30, conditions, and cast stainless steel performed. addition, examination welds wrought 304 also Microstructural hardness testing zones heat affected were done for combinations base material.
