The Stainless Steel Market – 2019

Total production of stainless steel in 2019 is estimated to hit 55 million tonnes, as the overall market for these metals continues to grow around 5% per annum. With a production yield of c. 86%, this equates to just over 46MT of traded products (semis and finished products) in the global marketplace. Duplex, super duplex and super austenitic grades make up only 5% of the overall total global production, with just over half of this being duplex stainless steel.

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 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.
