Guidelines forGroups I, II, and III are predominately used for corrosion-resistant services, the Group IV alloys are used where higher strength is needed, although with usually some small sacrifice of corrosion resistance. Some physical properties and their influence on welding are shown in Table 2. Corrosion resistance of nickel alloy weldsHIGH-CHROMIUM ALLOY RESISTS AQUEOUS CORROSIONtest, Alloy 31 was resistant at temperatures up to 40°C (100°F) and chlorine levels up to 2 ppm. Only at a temperature of 50°C (120°F) and a chlo-rine level of 2 ppm did alloy 31 show slight crevice corrosion on two out of the ten flange joints. In contrast, when placed in North Sea water, which has much greater salinity, the alloy was re-

Superior resistance to chloride pitting and crevice corrosion.Alloy 625 - Corrosion MaterialsAlloy 625 is a Ni-Cr-Mo alloy that is used for its high strength, high toughness, and its oxidation and corrosion resistance. Strength of alloy 625 is derived from the stiffening effect of molybdenum and niobium on its nickel-chromium matrix. Although the alloy
alloys contain additives such as copper or tungsten, which enhance corrosion resistance of the alloy to which they are deliberately added, but they can have disastrous effects on the ability to recycle excess material. For example, copper is added to cobalt-base alloys to enhance corrosion resistance. Several corrosion resistant cast alloys contain this element,Monel metal supplier, Monel Alloy r405, Monel alloy 40501004: H2S RESISTANT MATERIALS FOR OIL&GAS Alloy 31 (UNS N08031) is a high alloyed stainless steel containing 31% Ni, 27 % Cr and 6.5 % Mo, which has found wide application in chemical and petrochemical process industry due to its high resistance in a variety of corrosive environments 3'4. However, its high resistance to localised corrosion in
01004: H2S RESISTANT MATERIALS FOR OIL&GAS on UNS N08825 and UNS N08028 is listed in Table 9. It can be seen that alloy 31 is more resistant to stress corrosion cracking than UNS N08028, which passed this tests under the same conditions at a temperature of 149 °C (300 °F) but failed at 177 °C. UNS N08825 passed the corrosion test but only inCORROSION RESISTANT ALLOYS-MECHANICAL (SG) PTE. CORROSION RESISTANT ALLOYS-MECHANICAL (SG) PTE.
