High-strength low-alloy steel - Wikipedia
Copper silicon nickel chromium and phosphorus are added to increase corrosion resistance. Zirconium calcium and rare-earth elements are added for sulfide-inclusion shape control which increases formability. These are needed because most HSLA steels have directionally sensitive properties.
Corrosion resistance and performance of copper–nickel and ...
Three alloys namely copper–nickel alloys UNS C70600 and C71500 and titanium-based UNS R50400 were included in the study along with other ferric-based alloys. Tests were conducted in both liquid and vapor environments under well controlled conditions at three different temperatures: 90 70 and 50°C for durations ranging from 30 to 300 days.
