 |
|
| |
| A fully austenitic rutile - basic 20.25.4, 5 weld metal
with better corrossion resistance to sulphuric acid
than lower alloyed weld metals of AISI 316L and
317L type. |
| |
| Description and Applications |
| OK 69.33 is designed for welding of stainless steel
with corresponding composition. This type of steel has
better resistance to sulphuric acids than lower alloyed
stainless steels. OK 69.33 is recommended for swedish
Standard Standard steel SS 2562, Avesta 254 SLX
UHB 904L, Sandvik 2 RK 65, 2R N65. |
