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 1930’s. 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.

However, with the encouragement of time spent at elevated temperatures, the solubility of certain elements in the alloy will change. This means that precipitates – combinations of selected elements – come out solution and appear as small particles distributed throughout the alloys microstructure. The precipitate particles act to ‘pin’ grain boundaries within the microstructure of the alloy, which hinders their movement when the alloy is being strained. This increases the yield strength of the alloy. Depending upon the combination of temperature and time used for the ageing heat treatment, both the number, size and distribution of precipitates can vary. Therefore, it is possible to produce a range of different strength levels within the same alloy composition, purely by altering the temperature and time of the ageing heat treatment.

What is NACE MR0175?

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.

Duplex Stainless Steels

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 […]

The difference between S31803 and S32205

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, […]

Alloy 825

Alloy 825 can perhaps be seen as the entry point when moving from stainless steels to more expensive Nickel alloys. With >40% Ni and >20%Cr content, then it is certainly a step-up in price compared with super duplex alloys. So, why would you specify it ?   Nickel-Iron-Chromium alloys such as Alloy 825, also known as Incoloy […]

Alloy 400 vs. Alloy K500

Summary: There is negligible difference in the composition of Alloy K500 versus Alloy 400, therefore their corrosion resistance is comparable. However Alloy K500 has several times greater yield and tensile strength, making it more suitable for heavily loaded applications. Langley Alloys stocks a wide range of sizes from 5/8” up to 10” diameter solid round […]
