ASTM A588 Grade B vs IS 11169 (Part 1) 21Ni2Cr2Mo2

Related Material — 63.6% match based on chemical composition and mechanical property overlap.

ASTM A588 Grade B (ASTM A588) and IS 11169 (Part 1) 21Ni2Cr2Mo2 (IS 11169 (Part 1):2022) are both steel grades. ASTM A588 Grade B is classified under Structural Steel (Corten / Weathering), while IS 11169 (Part 1) 21Ni2Cr2Mo2 is classified under Alloy Steel — a different category, which is worth noting alongside the chemistry match below. ASTM A588 Grade B is typically used for high-strength low-alloy structural steel with atmospheric corrosion resistance (weathering steel); bridges, transmission/communication towers, gusset plates, exposed structural applications, while IS 11169 (Part 1) 21Ni2Cr2Mo2 is commonly used for cold heading and cold extrusion of parts that are case hardened; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex b). ASTM A588 Grade B is defined under ASTM International, originating from United States, while IS 11169 (Part 1) 21Ni2Cr2Mo2 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, ASTM A588 Grade B vs IS 11169 (Part 1) 21Ni2Cr2Mo2 is a 63.6% 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 63.6%.
