BS 970 EN201 vs IS 11169 (Part 1) 27C15

Strong Match — 86.7% match based on chemical composition and mechanical property overlap.

BS 970 EN201 (BS 970:1955) and IS 11169 (Part 1) 27C15 (IS 11169 (Part 1):1984) are both steel grades. Both fall under the Carbon Steel category. BS 970 EN201 is typically used for bars and billets for forging; forgings and drop-forgings; bars for machining; bright bars. suitable for tensile strength of 40 tons/sq in min., while IS 11169 (Part 1) 27C15 is commonly used for manganese case-hardening steel; used for gears, shafts, and machine components requiring case hardening where higher core strength than plain carbon grades is needed. BS 970 EN201 is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 1) 27C15 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, BS 970 EN201 vs IS 11169 (Part 1) 27C15 is a 86.7% 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 86.7%.
