IS 1570 (Part 7) 16Mo3H vs IS 11169 (Part 1) 35Mn6Mo3

Close Alternative — 71.5% match based on chemical composition and mechanical property overlap.

IS 1570 (Part 7) 16Mo3H (IS 1570 (Part 7):1992) and IS 11169 (Part 1) 35Mn6Mo3 (IS 11169 (Part 1):2022) are both steel grades. Both fall under the Alloy Steel category. IS 1570 (Part 7) 16Mo3H is typically used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature, while IS 11169 (Part 1) 35Mn6Mo3 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). IS 1570 (Part 7) 16Mo3H is defined under Bureau of Indian Standards (IS), originating from India, while IS 11169 (Part 1) 35Mn6Mo3 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, IS 1570 (Part 7) 16Mo3H vs IS 11169 (Part 1) 35Mn6Mo3 is a 71.5% 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 71.5%.
