What is Inconel 718?

Alloy 718 is a high-strength, corrosion-resistant nickel chromium alloy.

Can nickel alloys be used at low temperatures?

Nickel alloys retain their room temperature properties over a far wider temperature range than many stainless steels.

What are copper nickels?

Copper-nickel alloys (cupronickels) provide the most acceptable high-strength option for a copper alloy.

What is Nitronic®?

Nitronic is a trademark belonging to AK Steel Inc and covers a family of more highly alloyed austenitic stainless steels.

Can stainless steel be used at low temperatures?

Austenitic stainless steels retain their impact strength at very low temperatures.

What is the difference between duplex and super duplex stainless steels?

Duplex stainless steels are based around a composition of 22% chromium, whereas super duplex stainless steels are based around 25%.

What are the applications for duplex stainless steels?

2205 duplex is used in applications where Alloy 316L is not sufficient, but the cost differential to super duplex grades is too great.

Super Duplex

What is sigma phase in duplex stainless steel?

Sigma phase is a chromium-rich intermetallic phase found in stainless steels, that forms when an alloy is cooled slowly.

What does Hiduron® mean?

Hiduron is a trademark belonging to Langley Alloys Ltd and applies to a family of high-strength copper – nickel alloys.

What is AMS5666?

AMS5666 is a specification covering the supply of an alloy similar in composition to Inconel 625 for aerospace applications. It covers multiple different product forms including forgings, extrusions and rings, although we are most interested in the stocking and distribution of solid bars. What is AMS5666? AMS stands for ‘Aerospace Material Specifications’ and AMS5666 is […]

What is Inconel 625 Grade 2?

Inconel 625 is a nickel-based alloy, also known in the Unified Numbering System (UNS) as N06625, Alloy 625 or DIN 2.4856. The Two Grades of Inconel 625 According to ASTM B446 it can be supplied in two different conditions: Grade1 Inconel 625 Grade 1 is the product in Annealed condition. This is the most commonly […]

What is NES835?

NES835 is commonly used to describe the alloy better-known as Hiduron 191 (UNS C72420). The Hiduron family of alloys were developed by Langley Alloys in the late 1930s. This alloy was immediately adopted for naval applications during the second world war. Today, it continues to be used in a wide range of industries and applications. […]
