Descriptionसंरचनात्मक इस्पात - Sanrachnātmak Ispāt (Structural Steel) is a ferrous alloy primarily composed of iron and carbon, with additions of manganese, silicon, and other elements to enhance mechanical properties [1]. Its high tensile strength (250-700 MPa) and yield strength (250-550 MPa) make it suitable for load-bearing applications. Density is approximately 7.85 g/cm³, and the modulus of elasticity is around 200 GPa. While not traditionally used in ancient Indic architecture constructed from *shilā* (stone) and *dāru* (wood), modern temple construction and restoration increasingly employ इस्पात for reinforcement. Sources of iron ore (*ayas*) historically included mines in Bihar and Odisha. Conservation efforts for heritage structures using इस्पात must address corrosion, a significant degradation factor. Modern processing involves smelting and alloying, differing significantly from traditional *lohakarman* (ironworking) techniques. Its durability depends on grade and environmental conditions. The material's use reflects a shift from traditional materials to modern engineering solutions.

Conservation Notes

Notes
  • Susceptible to corrosion
  • Requires protective coatings
  • Galvanization or epoxy coatings are used for corrosion prevention
  • Regular inspection for rust and section loss
  • Galvanization or painting is essential
  • Fatigue
  • Weld defects
  • Galvanic corrosion
  • Weld decay can occur in certain grades
  • Weld joints need regular inspection
