We offer the following alloys:

 

Kanthal APM

Kanthal APM is an advanced powder metallurgical, dispersion-strengthened, ferritic iron-chromium-aluminium (FeCrAl alloy) alloy for use at temperatures up to 1425 °C (2600 °F). The alloy is characterized by exceptionally good shape stability and oxidation resistance. Kanthal APM has low aging tendency and low resistance change. It also has excellent surface oxide properties, providing good protection in corrosive atmospheres and in atmospheres with a high carbon potential. There is no deposition. The unique combination of excellent oxidation properties and dimensional stability contributes to a long service life of the elements. The superior dimensional stability of the alloy reduces the amount of element support.

Alloy 230

Alloy 230 has outstanding oxidation resistance and superior strength up to 1149 °C. Comparable to Alloy 600, Alloy 230 exhibits excellent nitriding and carburising resistance. The alloy is one of the most nitriding-resistant materials available. Alloy 230 has excellent creep and fatigue resistance combined with long-term stability. In addition, the alloy is resistance to grain coarsening when subject to elevated temperatures for prolonged periods. Alloy 230 is easily fabricated and welded. As a result of its good ductility, Alloy 230 is readily formed by cold working.

Alloy 310/310S

Alloy 310S is widely used in moderately carburizing atmospheres such as those encountered in petrochemical environments. The more severely carburizing atmospheres of industrial heat-treating furnaces require RA330 or RA333. Alloy 310S is not suggested for the severe thermal shock of repeated liquid quenching. The grain size and carbon content meet both 310S and 310H requirements. Alloy 310S is often used at cryogenic temperatures, with excellent toughness and low magnetic permeability. Alloy 310S has good machinability and is readily fabricated.

Alloy 253MA

Despite its lean nickel content, 253 MA alloy offers an outstanding combination of creep strength and high resistance to oxidation, sulphidation and erosion/abrasion at extremely high temperatures. This makes the alloy more economical than most heat resistant alloys. The high heat resistant properties of 253 MA are obtained by the tight control of micro alloy additions. Whilst the benefit of creep rupture strength is down to the combination of nitrogen, carbon and cerium, its superior oxidation resistance is a result of the combination of cerium and silicon.

Alloy 330

The chemical composition of RA330 has changed over the years to allow for improved performance in the thermal process industry. RA330 is the workhorse of the heat resistant alloys with good strength and oxidising resistance up to 1148°C. In addition, the alloy is excellent in carburising and nitriding environments. RA330 remains fully austenitic at all temperatures so it is not subject to sigma embrittlement. It is highly resistant to chloride-induced stress corrosion cracking and thus an alloy of choice where common stainless grades has failed by stress corrosion cracking.

Inconel 600/601

With high nickel content, Inconel Alloy 600 is virtually immune to chloride-induced stress corrosion cracking. The alloy has superb corrosion resistance to caustic environments and resistance to dry chlorine up to 538°C. This alloy has excellent oxidation resistance up to 1093°C combined with high carburisation resistance and demonstrates good performance in high temperature nitriding environments. It is not recommended that Inconel® Alloy 600 be used at red heat temperatures where sulphur is present. It has also been found that Inconel® Alloy 600 can fall victim to stress corrosion cracking in hot, concentrated caustic alkalis, however, this can be avoided if the fabrication is fully stress relieved before use. Recommended stress relieving temperature of 982-1010 °C for 1 hour yields the best performance.

Nickel 200/201

Alloy 200/201 is extremely resistance to caustic alkalies up to and including the molten state. The extra-low carbon content of Alloy 200/201 gives virtual immunity to intergranular attack above about 315°C. The presence of chlorates must be kept to a minimum, as they accelerate the rate of attack.
