Whose hardness is higher between 20# steel and45# steel, S275M steel? Both 20# steel and 45# steel belong to high-quality carbon structural steel. According to the characteristics of high-quality carbon structural steel, its carbon content determines the performance of the steel. The higher the carbon content, the higher the hardness and strength of the steel, the lower the plasticity and toughness. The carbon content of No.20 steel and No.45 steel are 0.20% and 0.45% respectively, which shows that the hardness of No.45 steel is higher under the same process.
"Turkey has filed a lawsuit against EU steel import tariffs with the world trade organization, the trade ministry said Friday. In February 2019, the European Union said that the sharp increase of Turkish steel imports S275M steel seriously threatened the steel producers in member countries. The European Union has set import quotas for 26 kinds of steel products and imposed a 25% tariff on future steel products for three years.
