Inconel 625

Inconel 625 was developed in the 1960’s and achieves reasonably high strength through the addition of molybdenum and niobium to the nickel-chromium base. This imparts solution-strengthening, meaning that no additional heat treatment stage is required. It can comfortably be used up to 650degC with little loss of mechanical properties, and actually retains much of its strength up to 800degC and down to cryogenic temperatures.

The role of copper in improving corrosion resistance of stainless steels

Copper is normally present in stainless steel as a residual element only. However, it is added to selected alloys in order to enhance their corrosion resistance, particularly in seawater and sulphuric acid solutions. For many years, copper has been seen as an undesirable element within steel production. It has been associated with ‘hot shortness’, where […]

The role of molybdenum in improving corrosion resistance of stainless steels

The most common application of molybdenum is in the production of stainless steels and nickel-based alloys. Molybdenum is widely understood to improve the resistance to pitting corrosion of stainless steels, and therefore is a key alloying element in their composition. Duplex, super duplex and austenitic stainless steels within Langley Alloys stock range all utilise molybdenum.

Inconel 718

Nickel-chromium alloys are probably the most widely used nickel-based alloys. They are characterised by their excellent corrosion resistance at both ambient and elevated temperatures – forming a protective film that prevents further oxidation and retention of their mechanical properties over a wide temperature range. They are better known by the Special Metals Corporation tradename Inconel®, […]

Incoloy 825

Incoloy® 825 (UNS N08825/W.Nr. 2.4858) is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. The Incoloy family of alloys are all based upon a nickel-iron-chromium base composition, but with a varying number of additional alloying elements. They were originally developed and produced by the Special Metals Corporation group of companies, which includes the […]
