BIS CERTIFICATION FOR QUENCHED AND TEMPERED ALLOY STEEL FORGINGS IS 12145:1987

Quenched and tempered alloy steel forgings are special metal parts made from strong alloy steel. They go through a two-step heating process to become tough and strong. First, they're heated a lot and then quickly cooled using oil, water, or special liquids. This makes them very hard but a bit brittle. Next, they're heated again, but not as much, and then slowly cooled carefully. This makes them less hard but tougher and less likely to break. These special forgings end up being just right, tough and strong at the same time. They're used in airplanes, cars, oil industry, and buildings where we need strong and reliable parts.

According to IS 12145:1987, forgings are categorized into three grades: I, II, and III, based on chemical composition (C, Mn) and mechanical properties (YS, TS, Elongation, Impact). Grades I and II further have subcategories, I A, I B, II A, and II B, with higher YS for the 'B' grades. Grade III features the lowest carbon content, the highest alloy content, and the highest YS among the three grades.

IS 12145:1987 pertains to quenched and tempered alloy steel forgings for pressure vessels. This standard outlines the requirements for forgings used in pressure vessel components, including vessel closures, flanges, shells, tube sheets, heads, rings, and similar parts within the reactor system.
