Navgraha Steel & Engg Company is a supplier and exporter of fasteners. SS 317L Fasteners are enhanced with outstanding strength and general corrosion resistivity made of low carbon stainless steel. Consequently, It increases the industrial application scope of these fasteners in several sectors, including the fabrication and processing industries. This attribute boosts the durability of these fasteners and improves functional performance. It is produced with a wide range of sizes, including different shapes and thicknesses of various fastener components like bolts, washers, anchors, studs, nuts. Also, it is accessible in custom sizes at lower costs compared to market rates.
SS 317L Fasteners are formed using low carbon austenitic steel SS 317L. It enhances the tensile strength of fasteners as well as provides higher mechanical strength. These fasteners are exposed to higher pressures with superb toughness to sustain extreme conditions. Moreover, these fasteners easily handle acid decomposition in the surrounding citric and acetic acids with excellent resistance. Moreover, it gives a smooth surface preventing pitting.
Stainless Steel 317L Fasteners also provide stress and creep rupture strength in higher loads applications added with less elongation coefficient. In addition, lower carbon content sensitization opposition affects higher temperature efficiency. Thus these fasteners can work in lower as well as higher temperatures with wide range series. Our fasteners are easily formable with excellent flexibility resulting in easily produced. It is unaffected by the sulfurization effect in sulphide surroundings.
