BS 970 EN6A vs IS 11169 (Part 1) 30C8

Strong Match — 90.2% match based on chemical composition and mechanical property overlap.

BS 970 EN6A (BS 970:1955) and IS 11169 (Part 1) 30C8 (IS 11169 (Part 1):1984) are both steel grades. Both fall under the Carbon Steel category. BS 970 EN6A is typically used for bars for machining. en 6a is identical in composition and mechanical properties with en 6 except for the omission of the izod impact value., while IS 11169 (Part 1) 30C8 is commonly used for cold heading and cold extrusion; the standard covers wires, wire rods and bars of 2 to 100 mm diameter (clause 1.1). BS 970 EN6A is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 1) 30C8 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, BS 970 EN6A vs IS 11169 (Part 1) 30C8 is a 90.2% 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 90.2%.
