IS 1570 (Part 2/Sec 1) 5C4 vs BS 970 (Part 1) 055M15

Strong Match — 93.6% match based on chemical composition and mechanical property overlap.

IS 1570 (Part 2/Sec 1) 5C4 (IS 1570 (Part 2/Sec 1):1979) and BS 970 (Part 1) 055M15 (BS 970 (Part 1):1991) are both steel grades. Both fall under the Carbon Steel category. IS 1570 (Part 2/Sec 1) 5C4 is typically used for rivet wire for the bearing industry and bearing cage strip (the standard links this grade to is 4882, is 4397), while BS 970 (Part 1) 055M15 is commonly used for as-rolled, or as-rolled and softened, steel (section two). IS 1570 (Part 2/Sec 1) 5C4 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 055M15 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 1570 (Part 2/Sec 1) 5C4 vs BS 970 (Part 1) 055M15 is a 93.6% 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 93.6%.
