Metals for Thermowells

A thermowell is a fitting designed to protect sensors when they are installed in aggressive environments in industrial applications. The thermowell will protect the sensor from impact, corrosion, oxidation, pressure and general damage. The most common designs of thermowell are sized to fit thermometers, thermocouples or resistance temperature detectors. The process fluid transfers heat to the […]

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.

What are duplex grades F51, F53, F55, F60 and F61?

F51, F53, F55, F60 and F61 are duplex and super duplex stainless steel designations taken from ASTM A182. This standard is one of the most widely referenced standards for the supply of stainless steels. The American Society of Testing and Materials (ASTM) is one of the world’s largest standards organisations, reviewing, collating and publishing technical […]

Super Duplex less impacted by Ni price increases

The production of all metals is subject to pricing pressure. Inflation, energy costs and employee wages are variables that affect all industrial producers. However, other consumables and raw materials have proven more volatile. The pricing of super duplex stainless steels is inherently less volatile than for nickel alloys. Graphite electrode surcharge In recent years, steel […]

What is Nitronic 50?

Nitronic 50 is a higher-performance austenitic stainless steel that provides approximately twice the yield strength of regular 3xx series stainless steels and improved corrosion performance. It is widely used in a variety of marine and industrial applications. Compared with Alloy 316L, it contains increased chromium and molybdenum additions which support the improved corrosion resistance. Whilst […]

What is S32760?

The origins of Alloy 32760 can be traced back to the development of the trademarked alloy Zeron 100 by Mather & Platt. This Manchester, England based foundry supplied castings for a number of applications, but this alloy was developed primarily for their product range of centrifugal pumps for the oil and gas industry. The Zeron […]
