Our Incoloy 825 plate is built to tackle the brutal conditions of offshore oil and gas platforms, delivering top-notch corrosion resistance to keep critical components like pipelines and heat exchangers running strong. This isn’t just metal—it’s a precision-engineered solution for the toughest environments in the industry. Let’s dive into what makes our Incoloy 825 plate a standout, from its robust materials to its critical applications, while exploring industry trends and why our company is the go-to choice for offshore durability.
We craft our Incoloy 825 plate from a high-performance alloy of 38-46% nickel, 19.5-23.5% chromium, with iron, molybdenum, copper, and titanium, ensuring exceptional resistance to corrosion and stress cracking. The high nickel content fights chloride stress-corrosion cracking, while molybdenum and copper tackle pitting and crevice corrosion in seawater and acidic media. Titanium stabilizes the alloy against intergranular corrosion, making it ideal for offshore environments. Available in thicknesses from 0.1875″ (4.8mm) to 2.00″ (50.8mm), it’s designed for easy forming and welding, meeting standards like ASTM B424 and ASME SB 424. Our rigorous testing ensures purity and consistency, delivering plates that resist sulfuric, phosphoric, and chloride-rich conditions, lasting 3-5 years in harsh offshore settings. This makes it perfect for oil and gas platforms, chemical processing, and marine applications.
