IS 11169 (Part 1) 30C7 vs BS 970 EN5B

Strong Match — 87% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 30C7 (IS 11169 (Part 1):2022) and BS 970 EN5B (BS 970:1955) are both steel grades. Both fall under the Carbon Steel category. IS 11169 (Part 1) 30C7 is typically used for cold heading and cold extrusion of parts that are quenched and tempered; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex c), while BS 970 EN5B is commonly used for mechanical properties are not part of the contractual obligations of specifications en 5a, en 5b and en 5c.. IS 11169 (Part 1) 30C7 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 EN5B is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 1) 30C7 vs BS 970 EN5B is a 87% 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 87%.
