DIN 17222 C80 vs IS 1570 (Part 2/Sec 1) 75C6

Strong Match — 88.6% match based on chemical composition and mechanical property overlap.

DIN 17222 C80 (DIN 17222:1979-08) and IS 1570 (Part 2/Sec 1) 75C6 (IS 1570 (Part 2/Sec 1):1979) are both steel grades. Both fall under the Carbon Steel category. DIN 17222 C80 is typically used for springs, music wire, high strength wire, cutting tools, while IS 1570 (Part 2/Sec 1) 75C6 is commonly used for cold rolled strip for springs and railway laminated springs (the standard links this grade to is 2507, is 3885). DIN 17222 C80 is defined under Deutsches Institut fur Normung (DIN), originating from Germany, while IS 1570 (Part 2/Sec 1) 75C6 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, DIN 17222 C80 vs IS 1570 (Part 2/Sec 1) 75C6 is a 88.6% 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 88.6%.
