IS 1570 (Part 7) 12Cr4Mo5H vs EN 10084 22CrMoS3-5

Close Alternative — 71.8% match based on chemical composition and mechanical property overlap.

IS 1570 (Part 7) 12Cr4Mo5H (IS 1570 (Part 7):1992) and EN 10084 22CrMoS3-5 (EN 10084:2008) are both steel grades. Both fall under the Alloy Steel category. IS 1570 (Part 7) 12Cr4Mo5H is typically used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature, while EN 10084 22CrMoS3-5 is commonly used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1). IS 1570 (Part 7) 12Cr4Mo5H is defined under Bureau of Indian Standards (IS), originating from India, while EN 10084 22CrMoS3-5 is defined under European Standard (EN), originating from Europe.

As per chemical composition, IS 1570 (Part 7) 12Cr4Mo5H vs EN 10084 22CrMoS3-5 is a 71.8% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a close alternative overall at 71.8%.
