IS 11169 (Part 1) 31Cr2Mo1BT vs SAE J404 4130

Related Material — 64.8% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 31Cr2Mo1BT (IS 11169 (Part 1):2022) and SAE J404 4130 (SAE J404:2000) are both steel grades. Both fall under the Alloy Steel category. IS 11169 (Part 1) 31Cr2Mo1BT 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 4130 is commonly used for chemistry-only alloy steel grade; see the composition notes for product scope. IS 11169 (Part 1) 31Cr2Mo1BT is defined under Bureau of Indian Standards (IS), originating from India, while SAE J404 4130 is defined under SAE International, originating from United States.

As per chemical composition, IS 11169 (Part 1) 31Cr2Mo1BT vs SAE J404 4130 is a 64.8% 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 64.8%.
