Types of SS 321/321H wire mesh offered are SS hexagonal wire mesh, SS netting wire mesh, SS welding wire mesh, SS fencing wire mesh. Types of SS321/321H bars offered are SS bright bars, SS square bars, SS hex bars, SS flat bars, SS rectangular bars, SS threaded bars.
Stainless steel 321 or UNS S32100 is titanium-based austenitic SS alloy with a very good property of resistance to general corrosion. It is having very good resistance ability against intergranular corrosion once it gets exposed to the temperature into the chromium carbide precipitation temperature range of 427-816 deg C. This alloy is resisting oxidation 816 Deg C and is having very good stress and creep-rupture properties than other alloys. Also, it holds very good low-temperature hardiness. SS 321H or UNS S32109 is the greater carbon content version of SS 321. This alloy is developed for improvising creep resistance and greater strength at a temperature ranging 537 Deg C. SS 321/321H rods, bars, wire, wire mesh is well tested before supplied to the clients. The test performed on it is toughness test, pitting resistance test, macro & micro test, flattening & flaring test, mechanical strength & chemical composition analysis.
