IS 11169 (Part 1) 23C8BT vs SAE J404 5120

Close Alternative — 70.8% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 23C8BT (IS 11169 (Part 1):2022) and SAE J404 5120 (SAE J404:2000) are both steel grades. Both fall under the Alloy Steel category. IS 11169 (Part 1) 23C8BT is typically 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), while SAE J404 5120 is commonly used for chemistry-only alloy steel grade; see the composition notes for product scope. IS 11169 (Part 1) 23C8BT is defined under Bureau of Indian Standards (IS), originating from India, while SAE J404 5120 is defined under SAE International, originating from United States.

As per chemical composition, IS 11169 (Part 1) 23C8BT vs SAE J404 5120 is a 70.8% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a close alternative overall at 70.8%.
