Arandela Muelle Valvula (Valve Spring Washer) is a component used in valves for avoiding leakage while withstanding high pressure. In a manufacturing industry, these valve spring washers are produced as per the customer needs. Based on grades, four different grades of Muelle variants are used, they are UNS S15500 (15 – 5 pH), UNS S17400 (17 – 4 pH), INCONEL X-718, INCONEL X-750. In these variants, UNS S15500 (15 – 5 pH) and UNS S17400 (17 – 4 pH) have almost similar element composition, except the chromium level. From the raw material UNS S15500 (15 – 5 pH) Sheet, Arandela Muelle (Spring Washer) are cut by either Waterjet cutting process, Laser cutting or Wire cutting processes. While examining, some UNS S15500 (15 – 5 pH) grade Arandela Muelle (Spring Washer) are reported as UNS S17400 (17 – 4 pH) grade steel, in the Positive Material Identification Test (PMI). To properly identifies the differences, other chemical and mechanical tests are carried out.
