Product Introduction
HAYNES 230-W alloy (UNS N06231) is a modified version of HAYNES® 230, designed to provide similar high-temperature strength and oxidation resistance with improved hot-working and fabrication characteristics.
By adjusting the alloy chemistry and processing route, Haynes 230-W offers better workability and consistency during forging and forming, making it especially suitable for forged products, rings, and complex shaped components requiring excellent thermal stability.
The alloy maintains very good resistance to oxidation, carburization, and nitriding, ensuring reliable long-term performance in high-temperature industrial environments.

Q1: What makes INCOLOY 800 different from other nickel alloys?
A1: INCOLOY 800 is specifically designed for high-temperature structural stability, combining nickel's corrosion resistance with iron's strength and chromium's oxidation protection.
Q2: What environments can INCOLOY 800 be used in?
A2: It performs well in oxidizing, carburizing, and sulfur-containing atmospheres, commonly used in heat exchangers, reformers, and furnaces.
Q3: Is INCOLOY 800 suitable for welding and fabrication?
A3: Yes. It can be welded using TIG, MIG, or resistance welding, and maintains its mechanical integrity after welding.
Q4: What forms are available for INCOLOY 800?
A4: Sheets, plates, bars, pipes, tubes, rings, flanges, and custom forged parts are available upon request.
Q5: What certifications can be provided?
A5: Products can be supplied with EN 10204 3.1 / 3.2 certificates, showing full chemical composition and mechanical test results.
Q6: Are inspection certificates provided?
A6: Yes, EN 10204 3.1 / 3.2 certificates are available, including full chemical analysis and mechanical test reports.
Q7: What is the delivery time?
A7: Usually 7-15 working days for stock materials, and 20-30 days for custom-machined or special-size rings.
Q8: Do you offer price discounts for large quantities?
A8: Yes. We provide big price discounts for bulk orders or long-term cooperation projects. Please contact us for a detailed quotation.
