Question 1

What is अकलंक इस्पात (Stainless Steel)?

Accepted Answer

स्टेनलेस स्टील (Sṭenalesa Sṭīla), also known as अकलंक इस्पात [1], is a ferrous alloy characterized by a minimum of 10.5% chromium, imparting exceptional जंगरोधी (corrosion-resistant) properties. Density ranges from 7.7-8.1 g/cm³; tensile strength, 500-1000 MPa [2]. While not traditionally used in ancient Indic architecture due to its modern origin (20th century CE), its durability makes it suitable for conservation efforts.

The primary geological origin is iron ore, historically sourced from regions like सिंहभूम (Singhbhum) [3]. Processing involves smelting, alloying, and shaping. Composition varies; nickel enhances ductility. Stainless steel finds application in modern structural supports and decorative elements replacing traditional materials like sandstone or wood where enhanced durability is required.

Conservation considerations include galvanic corrosion when in contact with dissimilar metals. Its use in heritage sites necessitates careful integration to minimize aesthetic disruption and ensure compatibility with existing materials. Its strength and resistance to biological degradation offer advantages over traditional materials in specific applications [1].
