Kalpatru is a well-known manufacturer of SS 317 / 317L Fasteners, which are used for various applications such as in Chemical Processing. Stainless Steel 317 Fasteners is particularly useful in control and instrumentation tubing applications where it is not suitable. The addition of copper to this grade of Stainless Steel 317L Fasteners gives it corrosion resistant properties superior to the conventional chrome nickel steels, in particular to sulphuric, phosphoric and acetic acids. SS 317 Fasteners is a ferritic, non-heat treatable stainless steel that provides good resistance to high temperature oxidation and corrosion. SS 317L Fasteners are high chromium, non-hardenable stainless steel with excellent corrosion resistance. These 317 Stainless Steel Fasteners are used in Cement kilns, Waste heat boilers, Molten lead, Salt baths, Heat treating, Incinerators, etc. 317L Stainless Steel Fasteners are general-purpose martensitic steels containing 11.5% chromium, which provide good corrosion resistance properties. However, the corrosion resistance of Stainless Steel UNS S31700 Fasteners can be further enhanced by a series of processes such as hardening, tempering and polishing. Quenching and tempering can harden this grade of Stainless Steel UNS S31703 Fasteners, which are quite reasonable rates to our valuable customers. WNR 1.4438 Fasteners was developed for enhanced creep resistance and for higher strength at temperatures above 1000°F (537°C). Alloy 317 Fasteners are being used in various applications such as for Boiler tubes, preheaters and heat exchangers.
