IS 1570 (Part 2/Sec 1) 65C6 vs SAE J403 1566

Strong Match — 93.5% match based on chemical composition and mechanical property overlap.

IS 1570 (Part 2/Sec 1) 65C6 (IS 1570 (Part 2/Sec 1):1979) and SAE J403 1566 (SAE J403:2014) are both steel grades. Both fall under the Carbon Steel category. IS 1570 (Part 2/Sec 1) 65C6 is typically used for billets and bars for forgings, carbon steel forgings, cold rolled strip for springs and spring washers (the standard links this grade to is 1875, is 2004, is 2507, is 4072), while SAE J403 1566 is commonly used for chemistry-only grade; product scope as listed in the composition notes. IS 1570 (Part 2/Sec 1) 65C6 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J403 1566 is defined under SAE International, originating from United States.

As per chemical composition, IS 1570 (Part 2/Sec 1) 65C6 vs SAE J403 1566 is a 93.5% 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 93.5%.
