Sixty-plus grades across five families — specified by UNS number, supplied with a certificate that names it.
Nickel–molybdenum, nickel–chromium–molybdenum and super austenitic grades for acids, chlorides and sour service.
28 grades in the programme
Nickel- and iron–nickel-based superalloys for turbine, furnace and high-temperature process service.
22 grades in the programme
Family overview →Invar, Kovar and soft-magnetic nickel–iron grades for instruments, seals and electronic packaging.
6 grades in the programme
Precipitation-hardening stainless and ultra-high-strength grades for load-critical components.
7 grades in the programme
Family overview →Super austenitic, duplex and 300-series grades with tightly controlled chemistry.

Family overview →The grades we are asked about most often, with chemistry, service limits, applications and the forms we supply.
The default alloy for mixed acids, chlorides and wet chlorine — and the grade most often specified when no one is sure what the stream will do.
Alloy detailChromium-rich cousins of C-276: better in oxidising media and in wet chlorine, with C-4 for hot ductility.
Alloy detailNickel–molybdenum alloys for hydrochloric acid — any concentration, any temperature within the practical range.
Alloy detailOne alloy for seawater, sour gas and 600 °C strength — the workhorse of offshore and supercritical service.
Alloy detailThe classic nickel–chromium alloy for caustic, high-temperature chlorine and furnace hardware.
Alloy detailBuilt for cyclic oxidation and carburising atmospheres up to about 1,100 °C.
Alloy detailHigh-chromium alloy developed against intergranular attack in nuclear steam generators and nitric/HF service.
Alloy detailNickel–copper alloy for hydrofluoric acid, seawater and hot concentrated alkali.
Alloy detailTitanium-stabilised nickel–iron–chromium alloy for sulphuric and phosphoric acid up to about 550 °C.
Alloy detailIron–nickel–chromium alloys for reformer tubing, furnace coils and high-temperature process piping.
Alloy detailSuper austenitic stainless with PREN above 42 — the economic answer to chlorinated seawater.
Alloy detailPrecipitation-hardening stainless reaching 1,100–1,300 MPa without losing corrosion resistance.
