Corrosion-resistant Inconel 625 alloy stainless steel plate
Corrosion-resistant Inconel 625 alloy stainless steel plate
Inconel 625 is a high-strength, corrosion-resistant nickel-chromium-molybdenum alloy (not stainless steel), renowned for its excellent resistance to high temperatures, pitting, crevice corrosion, chloride stress corrosion, and a wide range of corrosive environments. Due to its niobium and molybdenum content, the alloy exhibits high strength without precipitation hardening. Inconel 625 corrosion-resistant plate is widely used in demanding applications such as aerospace, offshore oil and gas, chemical processing, and marine. It is available in a variety of forms, including plate.
What are the advantages of using Inconel 625?
Inconel 625 alloy offers the following properties, making it an ideal choice for seawater applications: low susceptibility to localized corrosion (pitting and crevice corrosion), high corrosion fatigue strength, high tensile strength, and resistance to chloride-ion stress corrosion cracking.
Inconel 625 Plate Corrosion Resistance:
625 alloy plate exhibits excellent corrosion resistance in a wide range of media.
In chloride-containing media, it offers excellent resistance to pitting and crevice corrosion, as well as impact and intergranular corrosion.
It also exhibits high corrosion resistance to inorganic acids such as nitric, phosphoric, sulfuric, and hydrochloric acids, as well as alkali metal and organic acids under both oxidizing and reducing conditions.

Corrosion-Resistant 625 Alloy Plate Properties
Adaptable to a Wide Range of Environments: 625 alloy offers excellent corrosion resistance to both oxidizing and nonoxidizing acids, as well as high-temperature sulfides and chlorides.
Pitting and Crevice Corrosion: High molybdenum and chromium contents provide excellent resistance to pitting and crevice corrosion.
Stress Corrosion Cracking: Its resistance to chloride-ion stress corrosion cracking makes it suitable for marine and sour gas applications.
High-Temperature Corrosion: The alloy resists high-temperature effects such as oxidation and carburization.
