Our Certifications
Steel Sales Co is one of the reputed steel companies situated in the metro city of Mumbai. We are known well for the quality of Duplex S31803 Flanges manufactured and exported by us. Our services also include the distribution and dealing of the Duplex S31803 Flanges manufactured by the large steel magnates. We are also vigorously indulged in the stocking of these Duplex S31803 Flanges. We are certain about us customizing the Duplex S31803 Flanges in the sizes, shapes, and all the other dimensions which are required by our clients.
The Duplex Steel 31803 Flanges formulated by us are hyper alloy forms of stainless steel. These Duplex S31803 grade products are available in all three categories of alloys, no specification is carried out. Thus, the DS31803 Flanges are of all three, austenitic, martensitic, and ferritic versions of the hyper stainless steel alloys. They are also accessible in the hardened form by the process of precipitation. The elements and their concentrations present in the Duplex S31803 grade provides these Flanges with a very impeccable crystalline structure. The elemental base of the stainless steel is formed mainly of the element of chromium when compared with other kinds of steel. In the hyper stainless steel alloys, the chromium content is substantially increased which results in the gain of excellent resistance against corrosion caused in general and unconventional atmospheric conditions. The other usual but important mechanical properties that the Duplex S318903 Flanges possess are the good amounts of resistance against a number of damaging actions like pitting and crevice corrosion, stress corrosion cracking, sulphide stress corrosion along sulfide attacks. These Duplex S13803 Flanges also function very well in the surroundings inclusive of chlorine. These Duplex S31803 Flanges are composed of the elements that make them wee-hardened and too strong which leads to the DS 31803 Flanges having a bad forming ability.
The Duplex S 31803 Flanges that are operated by us are supplied and distributed to the factories belonging to an array of industries. Hence, some of the most important industries where these flanges are fabricated are the pharmaceutical industry, energy industry, oil and gas, aerospace industry and even the marine industry. There are some appliances too, like the flue gas filter, heat exchangers, distillation components, chemical tanks, etc.
