Technological properties
| Property | ||
|---|---|---|
| Application areas | Used in oil production equipment, surface and down hole equipment in sour gas wells. (it is used for down-hole and surface gas- well components including tubular products, valves, hangers, landing nipples, tool joints and packers) | |
| Corrosion properties | The alloy has outstanding resistance to general corrosion, pitting, crevice corrosion and stress corrosion as well as resistance to sulfide stress cracking and stress-corrosion cracking in “sour” (H2S containing) crude oil and natural gas | |
| Heat Treatment | Solution annealed at 980 – 1040°C. Age hardening at 730 – 750°C. | |
| Welding | Very good | |
