Haynes 188 is a heat-resistant cobalt-based alloy containing approximately 40% cobalt, which provides excellent temperature stability and magnetic properties. This alloy (2.4683) also includes about 22% nickel and chromium, as well as 15% tungsten. It stands out for its outstanding resistance to oxidation at temperatures up to 1100°C and its durability in sulphur-containing environments. Haynes 188 offers good ductility, corrosion resistance, and is highly resistant to abrasion and impact. While it is not age-hardenable, it is well-suited for cold forming processes.
At Evek GmbH Online Shop, you can purchase 2.4683 material with international shipping. As a trusted supplier of nickel alloys, we guarantee safe and efficient delivery.
