BS 970 (Part 1) 170H41 vs IS 11169 (Part 1) 26C10BT

Close Alternative — 80.3% match based on chemical composition and mechanical property overlap.

BS 970 (Part 1) 170H41 (BS 970 (Part 1):1991) and IS 11169 (Part 1) 26C10BT (IS 11169 (Part 1):1984) are both steel grades. Both fall under the Alloy Steel category. BS 970 (Part 1) 170H41 is typically used for through hardening boron steel (section three), while IS 11169 (Part 1) 26C10BT is commonly used for cold heading and cold extrusion; the standard covers wires, wire rods and bars of 2 to 100 mm diameter (clause 1.1). BS 970 (Part 1) 170H41 is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 1) 26C10BT is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, BS 970 (Part 1) 170H41 vs IS 11169 (Part 1) 26C10BT is a 80.3% 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 80.3%.
