Monel K-500 is not prequalified by AS1210 or the ASME Boiler & Pressure Vessel Code for use in pressure vessels. Please consult Austral Wright Metals for specific advice on your application. 0000022246 00000 n This treatment is also recommended to restore ductility after each 1000 hours of service above 650°C, due to long term precipitation of brittle sigma phase. ASTM B127 Titanium and its alloys are generally more difficult to forge than both aluminium and alloy steels, due to their high strain rate sensitivity and rapid increase of strength with falling temperature. In common with other austenitic stainless steels, these grades cannot be hardened by heat treatment. 310 is particularly susceptible due to its much higher carbon content. Corrosion rates in strongly agitated and aerated sea water are extremely low. The compositional ranges for 253MA, 310 and 310S, given in Table 1, are specified in ASTM A240/A240M. Inconel 600 is practically free from chloride ion stress corrosion cracking. After forging annealing is recommended to relieve all stresses from the forging process. AS1210, Pressure Vessels, allows the use of grade 310 up to 800ºC. Inconel 718 additionally offers exceptional tensile and impact power. They have good resistance to thermal fatigue and cyclic heating. It has excellent resistance to sea water. 0.294 lb./in. The Pitting Resistance Equivalent (PRE) is approximately 25, and seawater resistance about 22°C, similar to that of grade 316. Given a density of 2.72, we then get the product of 2.72 x 1,200 = 3,264 g or 3.264 kg. 1.4436 from its inventory.Starting from off shelf on-time delivery to all ranges of industrial products of steel and with its array of grades we provide solutions for rapidly … Even under biofouling and deposits, pitting and crevice corrosion are not encountered. 310/310S Good sulphidation and carburising resistance. This layer is called “Alpha Case” and is usually removed by pickling in a mixture of nitric and hydrofluoric acids. Titanium & Titanium Alloy Strip, Sheet & Plate, Specified Minimum Mechanical Properties – ASTM B265 Grade 310/310S is used in fluidised bed combustors, kilns, radiant tubes, tube hangers for petroleum refining and steam boilers, coal gasifier internal components, lead pots, thermowells, refractory anchor bolts, burners and combustion chambers, retorts, muffles, annealing covers, saggers, food processing equipment, cryogenic structures. The Austral Wright Metals Product Data Sheet “Corrosion of Titanium and Titanium Alloys” or your local office should be consulted more details. Mechanical Properties Titanium rarely suffers accelerated corrosion on coupling with other metals, but it may accelerate the corrosion of a more active metal coupled to it. Titanium is reactive, with a very high affinity for oxygen, which forms a skin of very stable and highly adherent oxide. Minor additions of other elements, such as palladium and nickel, can greatly reduce corrosion under these conditions, and made to highly corrosion resistant alloys such as grade 7. The rate of attack depends on many factors, including solution chemistry and temperature, and the cathode to anode surface area ratio. It also has good corrosion resistance due to the high nickel content in combination with chromium. Specific gravity (density) of stainless steel, etc. In more aggressive media nickel and chromium resist oxidising attack, while nickel and molybdenum resist reducing environments. Both 253MA and 310/310S are subject to stress corrosion cracking but more resistant than grades 304 or 316. It is highly resistant to chlorinated solvents, glass etching agents, sulphuric, hydrofluoric and many other acids, and practically all alkalies. The alloy can also be cold formed with heavy forces. The grades are resistant to oxidation, sulphidation and carburisation. 0000004513 00000 n 310/310S Inconel 601 has outstanding resistance to high temperature oxidation. Inconel 625 is difficult to machine (class D-2). The higher strength alloys have been found susceptible to SCC in aqueous chloride solutions at high stress levels in laboratory tests, but the problem is rarely encountered in practice. H2S) are not present. In the nuclear field, INCONEL alloy 625 may be used for reactor-core and control-rod components in nuclear water reactors.
