What is the difference between 20G and 20# steel grade? The difference between 20G and 20# steel is very big. The chemical elements, mechanical properties, service environment and price of 20G and 20# steel are very different. EN 10025-5 weathering steel S355J0W, 20G and 20# steel can not be compared. They are not of the same grade level, and can not be replaced by each other. 20# steel is high quality carbon structural steel, 20G steel is high pressure boiler steel. EN 10025-5 weathering steel S355J0W, 20# steel does not bear pressure, while the use temperature of 20G steel is 450~480℃.
15CrMo alloy steel plate is pearlite structure heat-resistant steel, which has high heat strength (δb≥440MPa) and oxidation resistance at high temperature, and has certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of steel EN 10025-5 weathering steel S355J0W is obvious and the weldability is poor. 15crmo alloy steel plate is mainly used in petroleum, petrochemical, high-pressure boilers, etc.
In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like EN 10025-5 weathering steel S355J0W, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.
