BS 970 (Part 3) 045M10 vs AISI 1010

Strong Match — 92.9% match based on chemical composition and mechanical property overlap.

BS 970 (Part 3) 045M10 (BS 970 (Part 3):1991) and AISI 1010 are both steel grades. Both fall under the Carbon Steel category. BS 970 (Part 3) 045M10 is typically used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; case hardening steel, carbon and carbon manganese (table 14), while AISI 1010 is commonly used for tubing, pipe, sheet, structural shapes, wire. BS 970 (Part 3) 045M10 is defined under British Standards (BS), originating from United Kingdom, while AISI 1010 is defined under AISI, originating from United States.

As per chemical composition, BS 970 (Part 3) 045M10 vs AISI 1010 is a 92.9% 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 92.9%.
