Gayatri Tubes is a reliable manufacturer that is fully engaged in manufacturing and offering the commendable quality of SS 347 / 347H rod, bars, wire, wire mesh. We as a manufacturer are making it available in different dimensions, lengths, types, standards, and specifications. Also, it is made available to the clients at custom-built specifications as per the demands of the clientele. All our offered ranges of SS rod, bars, wire, and wire mesh are designed according to the industry product quality standards such as ASTM, ASME, etc. Because of various good properties like resistance to stress corrosion cracking, good resistance to thermal fatigue and cyclic heating, anti-corrosiveness, sturdy construction, oxidation and pitting resistance, it is found used in various applications. Also, our product is appreciated as it easily holds high temperature, high pressure, good hardiness, etc. These SS rods, bars, wire, wire mesh is found in ranges of applications. Some of them are power generation, chemical equipment, seawater equipment, petrochemicals, offshore, specialty chemicals, chemical equipment, paper & pulp industry, condensers, pharmaceuticals and gas processing, and pharmaceuticals, etc.
SS 347/347H wires are subjected to SCC and are highly resistant to the other alloys. Also, it holds very good resistance against thermal fatigue/ cyclic heating. SS347H wires are use at temperature 425-860 deg C isn’t recommended, because of carbide precipitation. But it works very well into the temperature that fluctuates succeedingly or beneath this range. SS 347 bars are containing 10% of chromium. The presence of a stable film in square bars is preventing corrosion by limiting the access of water and oxygen to the underlying surface of the metal. SS hollow bar gets corroded on an atomic level but it appears to be stainless. SS 347H threaded bars provide a role in structural areas and fasteners. SS 347H hollow bar takes the benefit of low thermal expansion features. 347 SS wire mesh contains 18% chromium and 8% nickel. SS netting wire mesh isn’t harden-able through heat treatment and it is non-magnetic in nature. SS347 spring steel wires mesh contains 10.5%-27% chromium and is free of nickel. SS 347 / 347H rod, bars, wire, wire mesh is subjected to testing like PMI-IGC test, toughness test, macro-micro test etc.
