Conventional stainless steel alloys crack under pressure. They become susceptible and get easily corroded. However, Super Duplex grades such as ASTM A815 UNS S32750 Fittings resist localized corrosion like SCC or stress-related corrosion cracking.

Fittings are usually coated to improve their surface and improve mechanical or corrosion resistance properties. Some surface options include – polishing, black surface, peeling or turning and grounding.
The elbow could be either hot or cold formed. The fittings are treated by solution annealing at a minimum of 1052ºC, followed by quenching. It is important for the component to undergo rapid quenching by air or water immediately after annealing. Pickling and rinsing done to fittings increase their corrosion resistance properties.
The petrochemical industry requires equipment to have really high corrosion resistance properties with good mechanical strength and toughness. The temperature-pressure settings in this environment are at extremes, and refineries use harsh chemicals in the processing of petroleum. A Super Duplex S32750 End Cap, checks all these boxes, making it a useful fitting in the petrochemical sector.
These fittings are resistant to chloride ions and they work well in aggressive chloride-containing environments. It exhibits high mechanical strength and it has very good resistance to localized corrosion.
