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 […]

Duplex, 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 […]

What 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.
