IS 11169 (Part 1) 27C15 vs BS 970 (Part 1) 150M28

Strong Match — 92.6% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 27C15 (IS 11169 (Part 1):1984) and BS 970 (Part 1) 150M28 (BS 970 (Part 1):1983) are both steel grades. Both fall under the Carbon Steel category. IS 11169 (Part 1) 27C15 is typically 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, while BS 970 (Part 1) 150M28 is commonly used for wrought steel for mechanical and allied engineering purposes; supplied in the normalized condition (table 2).. IS 11169 (Part 1) 27C15 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 150M28 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 1) 27C15 vs BS 970 (Part 1) 150M28 is a 92.6% 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 92.6%.
