JIS G4053 SMn438 vs BS 970 (Part 3) 150M36

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

JIS G4053 SMn438 (JIS G4053:2008) and BS 970 (Part 3) 150M36 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Carbon Steel category. JIS G4053 SMn438 is typically used for agricultural equipment, heavy duty shafts, while BS 970 (Part 3) 150M36 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; carbon and carbon manganese steel (table 13). JIS G4053 SMn438 is defined under Japanese Industrial Standards (JIS), originating from Japan, while BS 970 (Part 3) 150M36 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, JIS G4053 SMn438 vs BS 970 (Part 3) 150M36 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%.
