AUSTINITIC STAINLESS STEEL ELECTRODE
RASI 307 R-16
VERSATILE, HIGH EFFICIENCY

CLASSIFICATIONS
AWS A/SFA 5.4 E 307- 16
IS : 5206 E 18.8MnR26

CHARACTERSTICS
RASI 307R-16 is a versatile austenitic Stainless Steel electrode with 19Cr-9Ni-6Mn. It has a high deposition efficency. The weld Metal is characterised by exceptional crack resistance and high deformability. The stable austenitic microstructure does not suffer any sigma phase formation. Weld metal tends to work Harden through deformation by impact and there by gains considerable abrasion resistance. 

APPLICANTIONS

RASI E 307R-16 Is a universal austenitic stainless steel type, suitable for variety of application.

Suitable for joining of austenitic steel to ferritic steels and it can be employed for service temperature up to 5500C

Steels resistance to scaling up to 8500C

Joining of austenitic Mn steels to other steels

In the reclamation of worn out parts can be used for buffer layer and hard facing
