GB/T 1591 Q355C vs EN 10084 15NiCr13

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

GB/T 1591 Q355C (GB/T 1591:2018) and EN 10084 15NiCr13 (EN 10084:2008) are both steel grades. GB/T 1591 Q355C is classified under Structural Steel, while EN 10084 15NiCr13 is classified under Alloy Steel — a different category, which is worth noting alongside the chemistry match below. GB/T 1591 Q355C is typically used for general structure for engineering (plates, strips, bars and sections), while EN 10084 15NiCr13 is commonly used for heavily loaded gears, cams, camshafts. GB/T 1591 Q355C is defined under Guobiao Standards (GB/T), originating from China, while EN 10084 15NiCr13 is defined under European Standard (EN), originating from Europe.

As per chemical composition, GB/T 1591 Q355C vs EN 10084 15NiCr13 is a 65.1% 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%.
