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.

Quality feedstock for Norsok castings

Langley Alloys recently supplied a significant quantity of Sanmac™ 2205 (F51/S32205) for a customer to use in the production of castings. The castings were destined for an offshore application, with the end client requiring Norsok approvals – which require feedstock produced by the AOD (argon oxygen decarburisation) process.
