We are best Manufacturers, Exporters & Stockists of Alloy 218 Bolts/Nuts in Oman. Nascent Pipe & Tubes offers an extensive collection of Alloy 218 Bolts / Nuts, which is typically furnished in the annealed condition. Alloy 218 Hex Head Bolts as fully austenitic alloy is originally designed as a temperature alloy, and subsequently has good high temperature properties for temperatures around 1800 Degree F. At room temperature, Alloy 218 Hex Head Nuts displays double the yield strength of grades 316 / 316L and 317 / 317L along with higher levels of oxidation resistance, especially in marine applications. Alloy 218 Square Bolts is used in the aerospace, food and drug, oil field, petrochemical, surgical and chemical processing industries.
Alloy 218 Square Nuts are also used as a plug in to resist pressure in Pressure Valves, and have huge demand in many large scale industrial purposes. The oxidation resistance of Alloy 218 Eye Bolts is similar to SS 309, and far superior to SS 304.
