Processing capabilities

Our cutting services include waterjets, lasers and bar saws.



Materials used in power boiler applications are selected for their creep strength and hot corrosion resistance in elevated temperature environments. Depending on the presence of chlorine, sulphur, alloys 253 MA®, 309/309S, 310S, 321, RA330®, and 601 are utilised. 253 MA® and 309/309S are commonly used for coal nozzles as well as other internal boiler parts such as tube supports, tube shields, and temperature probes. 253 MA® has been used in many CFB power boilers for cyclones due to having twice the creep strength of 309/309S and 310S stainless steel above 871°C and oxidation resistance up to 1093°C. RA330® has been used for soot blowers in power boilers due to its oxidation resistance up 1149°C and great thermal fatigue resistance in cyclic applications.

Pollution Control

Many of our alloys are used in pollution control systems, such as flue gas desulfurization (FGD) units, wet electrostatic precipitators (WESP), as well as some carbon capture absorbers. Due to the corrosive conditions caused by high aqueous chloride levels, acidic pH levels, and elevated temperatures, alloys with molybdenum additions are used to resist pitting and crevice corrosion. AL-6XN®, ZERON® 100, and UNS S32205 are used in many FGD and WESP applications, such as absorber vessels, wallpapering, ducting, turning vanes, pumps, slurry handling systems, impellers, and dampers. AL-6XN® has been in service for over 20 years in many FGD systems with no reported problems. Duplex grades UNS S32205 and ZERON® 100 are becoming a more popular material choice due to their high strength and lower relative price compared to higher nickel alloys. Duplex UNS S32205 has also been used in a pilot plant carbon capture absorber vessel.

Nuclear Power Plants

With more discussions on a clean energy future, nuclear power plants have been gaining more attention. AL-6XN® has been used in several cooling water systems that are using seawater as the process water or where MIC corrosion is of concern. ZERON® 100 would also be a candidate for these systems. 304L and 316L are commonly used for waste storage containers and glove boxes as well as heat exchangers and other transport equipment.
