BS 970 EN3 vs IS 11169 (Part 1) 15C4

Strong Match — 87.6% match based on chemical composition and mechanical property overlap.

BS 970 EN3 (BS 970:1955) and IS 11169 (Part 1) 15C4 (IS 11169 (Part 1):1984) are both steel grades. Both fall under the Carbon Steel category. BS 970 EN3 is typically used for bars and billets for forging; forgings and drop-forgings; bars for machining. suitable for a tensile range of 25/35 tons/sq in., while IS 11169 (Part 1) 15C4 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 EN3 is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 1) 15C4 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, BS 970 EN3 vs IS 11169 (Part 1) 15C4 is a 87.6% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a strong match overall at 87.6%.
