Super Resistance to Sulphuric Acid Corrosion |
| |
Asträ ZF is a high performance electrode with excellent
corrosion resistance to acids than the standard AISI
316L or 317L types where the alloy content is lower.
A rutile based electrode, Asträ ZF is characterized by
smooth running and a selfpeeling slag. |
| |
| |
| SPECIAL FEATURES |
- Stunning resistance to sulphuric, phosphoric, acetic
acids
- Smooth arc, a ripple free bead and a slag that removes
itself
|
| APPLICATIONS |
| The electrode is designed for welding stainless steels
of corresponding composition viz. Carpenter 20, SS
2562, Avesta 254 SLX UHB 904L, Sandvik 2RK65,
2RN65, etc. The weld deposit is resistant to sulphuric,
phosphoric, acetic, oxalic, formic and other acids like
fatty acids. The electrode can be successfully applied
in pipeline and storage applications handling the above
chemicals. |
