BS 970 (Part 1) 040A04 vs IS 1570 (Part 2/Sec 1) 5C4

Strong Match — 94.9% match based on chemical composition and mechanical property overlap.

BS 970 (Part 1) 040A04 (BS 970 (Part 1):1991) and IS 1570 (Part 2/Sec 1) 5C4 (IS 1570 (Part 2/Sec 1):1979) are both steel grades. Both fall under the Carbon Steel category. BS 970 (Part 1) 040A04 is typically used for as-rolled, or as-rolled and softened, steel (section two), while IS 1570 (Part 2/Sec 1) 5C4 is commonly used for rivet wire for the bearing industry and bearing cage strip (the standard links this grade to is 4882, is 4397). BS 970 (Part 1) 040A04 is defined under British Standards (BS), originating from United Kingdom, while IS 1570 (Part 2/Sec 1) 5C4 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, BS 970 (Part 1) 040A04 vs IS 1570 (Part 2/Sec 1) 5C4 is a 94.9% 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 94.9%.
