Hastelloy plates and sheets are high-performance nickel-based alloys that have been developed to survive extreme pressure, extreme temperatures, and active corrosion.
Stellar Alloys is a reliable supplier of Hastelloy plates and sheets in various grades, sizes, thicknesses, and surface finishes to facilitate the stringent industrial conditions.
Such alloys are particularly designed to be used in service where the standard stainless alloys and the traditional nickel alloys would fail because of aggressive chemicals, oxidizing media, or thermal variations. Their nickel-rich chemistry, with the addition of chromium and molybdenum controlled, allows them to remain viable in long-term periods of operation with varying operating conditions.
The Hastelloy flat products have good resistance against localized corrosion of the material, like pitting, crevice corrosion, and stress corrosion cracking. They are also good formers and welders of complex fabrics, should the correct procedures are observed.
All the Hastelloy plates and sheets purchased at Stellar Alloys are produced according to the standards of both the ASTM and ASME and are backed up by the complete traceability of the material and certifications.

Why Hastelloy Is Selected for Critical Applications
Hastelloy alloys are selected when using conditions are above the corrosion resistance and temperature limit of stainless steel and other conventional nickel alloys. Their high-level nickel-based chemistry is able to provide better withstand against acids, chlorides, and oxidizing settings and mechanical structural stability at high temperatures.
This Hastelloy replacement is usually necessitated by the need to have an extended life, low maintenance, and enhanced safety in harsh industrial conditions.
Why Choose Stellar Alloys for Hastelloy Plates and Sheets
The matter of selecting an appropriate source of Hastelloy plates and sheets is paramount because the quality of the materials chosen influences the quality of equipment safety, the equipment life, and the reliability of the equipment operations directly. Engineering firms and industrial buyers rely on Stellar Alloys to provide certified Hastelloy flat products, which are of high standards in the international arena.
We offer a wide variety of Hastelloy grades that are available in the form of plates, sheets, coils, strips, and shims. Every supply is supported by EN 10204 3.1 certification and may be supported by PMI, mechanical testing, and third-party inspection where necessary.
Our technical team helps to select the grade, meet the standards, and provide suitability of applications, besides supplying materials. Export-ready packaging and reliable and stable supply capacity make Stellar Alloys a reliable long-term supplier of Hastelloy plate and sheet.
