ASTM A537/A537M Class 1 vs IS 11169 (Part 1) 40Cr4Mo2

Related Material — 65% match based on chemical composition and mechanical property overlap.

ASTM A537/A537M Class 1 (ASTM A537/A537M:2013) and IS 11169 (Part 1) 40Cr4Mo2 (IS 11169 (Part 1):2022) are both steel grades. ASTM A537/A537M Class 1 is classified under Carbon Steel, while IS 11169 (Part 1) 40Cr4Mo2 is classified under Alloy Steel — a different category, which is worth noting alongside the chemistry match below. ASTM A537/A537M Class 1 is typically used for fusion welded pressure vessels and structures, while IS 11169 (Part 1) 40Cr4Mo2 is commonly 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). ASTM A537/A537M Class 1 is defined under ASTM International, originating from United States, while IS 11169 (Part 1) 40Cr4Mo2 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, ASTM A537/A537M Class 1 vs IS 11169 (Part 1) 40Cr4Mo2 is a 66.8% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a related material overall at 65%.
