Skytech Rolling Mill is a known manufacturer, exporter and trader of Stainless Steel 303 Square Bars, which is a nickel-base alloy generally similar to other alloys in aqueous corrosion. SS 303 Square Bars has excellent resistance to both reducing and oxidizing acids, to stress - corrosion cracking, and to localize attack such as pitting and crevice corrosion. Alloy 303 Square Bars is used in Fuel element dissolvers, Sea-water-cooled heat exchangers; offshore product piping systems; tubes and components in sour gas service. Grade 303 Square Bars is often used in heat exchangers, evaporators, scrubbers, dip pipes etc. in phosphoric acid production. The addition of titanium stabilizes Type 303 Square Bars against sensitization in the as-welded condition making the alloy resistant to intergranular attack after exposure to temperatures in a range that would sensitize un-stabilized stainless steels. SUS 303 Square Bars is resistant to corrosion in a wide variety of process environments including sulfuric, sulfurous, phosphoric, and nitric.
AISI 303 Square Bars can be readily welded by the shielded metal-arc process using alloy welding electrode 135, the gas shielded arc processes using alloy filler metal 65, and the resistance welding processes. Stainless Steel UNS S30300 Square Bars is especially resistant to sulfuric and phosphoric acids. SS DIN 1.4305 Square Bars is also used for chemical processing, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing. 303 Stainless SS Square Bars is an austenitic nickel-iron-chromium alloy with additions of molybdenum, copper and titanium.
