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 […]

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 […]

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 […]
View full articleDuplex, Super Duplex and Hyper Duplex
The development of duplex alloys has followed a trajectory of increasing alloy content and increasing levels of corrosion resistance and yield strength, from duplex to super duplex, to hyper duplex. The origin of duplex stainless steels can be traced back to the 1930s. Aggressive process environments in pulp and papermaking mills in Sweden spurred […]

Langley Alloys approached the Grants for Growth team at Stoke-on-Trent City Council for help with funding for a new capital expenditure project. Langley Alloys were looking to purchase an additional CNC lathe to increase the company’s capacity and allow them to provide extra services to their customers. As part of their investment, the company created […]
View full articleWhat is precipitation hardening?
The process of solution annealing is applied to most alloys after their final forging or rolling process. By holding the particular alloy at a relatively high temperature for several hours – typically around 1000degC – all of the different elements within the alloy are absorbed into the solid solution. By then immediately quenching the bar or plate, the structure is retained at room temperature.

NACE formally stands for the National Association of Corrosion Engineers, but is commonly used as short-hand for the internationally recognised standard NACE MR0175. A ‘NACE compliant’ product, really meaning one that is compliant to NACE MR0175, is one that meets the requirements of NACE MR0175 and therefore can be considered for sour service environments within the set operational limits.

If you were looking for property in North America, then duplex is an apartment split over two floors. In printing terminology duplex printing is the ability to print on both sides of a piece of paper. However, in stainless steels, duplex means a hybrid microstructure to attain a combination of properties. The most widely produced […]

Duplex stainless steels account for >80% of the consumption of duplex, super duplex and hyper duplex grades. Developed in the 1930’s for application in paper and pulp manufacture, duplex alloys are based around a 22% Cr composition and the mixed austenitic:ferritic microstructure that delivers desirable mechanical properties. Compared with the generic 304/316 austenitic stainless steels, […]
