WebReformer tubes are made of centrifugally cast heat-resistant alloys. In the 1960s and 1970s, most tubes were made of alloy HK-40 (25Cr-20Ni-Fe). In the 1980s and early 1990s, many reformers started using Nb-modified HP alloy (25Cr-35Ni-Nb-Fe) because it has been creep strength than the HK-40 alloy. WebHeats of several different alloys were prepared in accordance with the invention by adding small quantities of molybdenum, tungsten, columbium, zirconium, titanium and mischmetal to otherwise basic ACI-type (HF, HH, HK, HN and HP) alloys. Well-risered standard ASTM test bar keel blocks were cast from each heat.
