IS 11169 (Part 1) 10C4GC vs IS 11169 (Part 1) 25C5BT

Related Material — 65% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 10C4GC (IS 11169 (Part 1):2022) and IS 11169 (Part 1) 25C5BT (IS 11169 (Part 1):2022) are both steel grades. IS 11169 (Part 1) 10C4GC is classified under Carbon Steel, while IS 11169 (Part 1) 25C5BT is classified under Alloy Steel — a different category, which is worth noting alongside the chemistry match below. IS 11169 (Part 1) 10C4GC is typically used for cold heading and cold extrusion of parts not heat treated after cold forming; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex a), while IS 11169 (Part 1) 25C5BT is commonly used for cold heading and cold extrusion of parts that are quenched and tempered; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex c). IS 11169 (Part 1) 10C4GC is defined under Bureau of Indian Standards (IS), originating from India, while IS 11169 (Part 1) 25C5BT is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, IS 11169 (Part 1) 10C4GC vs IS 11169 (Part 1) 25C5BT is a 65.8% 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 65%.
