IS 6911 X108Cr17Mo vs IS 11169 (Part 2) X04Cr17Ni12Mo2Ti
Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
IS 6911 X108Cr17Mo (IS 6911:1992) and IS 11169 (Part 2) X04Cr17Ni12Mo2Ti (IS 11169 (Part 2):1989) are both steel grades.
Both fall under the Stainless Steel category.
IS 6911 X108Cr17Mo is typically used for stainless and heat-resisting steel plate, sheet and strip (clause 1.1), while IS 11169 (Part 2) X04Cr17Ni12Mo2Ti is commonly used for cold heading and cold extrusion; the standard covers wires, wire rods and bars (clause 1.1).
IS 6911 X108Cr17Mo is defined under Bureau of Indian Standards (IS), originating from India, while IS 11169 (Part 2) X04Cr17Ni12Mo2Ti is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, IS 6911 X108Cr17Mo vs IS 11169 (Part 2) X04Cr17Ni12Mo2Ti is a 72.2% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
