IS 11169 (Part 1) 34C14BT vs BS 970 (Part 1) 174H20

Close Alternative — 80.8% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 34C14BT (IS 11169 (Part 1):1984) and BS 970 (Part 1) 174H20 (BS 970 (Part 1):1991) are both steel grades. Both fall under the Alloy Steel category. IS 11169 (Part 1) 34C14BT is typically used for cold heading and cold extrusion; the standard covers wires, wire rods and bars of 2 to 100 mm diameter (clause 1.1), while BS 970 (Part 1) 174H20 is commonly used for case hardening steel (section four). IS 11169 (Part 1) 34C14BT is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 174H20 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 1) 34C14BT vs BS 970 (Part 1) 174H20 is a 80.8% 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 80.8%.
