"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 S420MC chemical composition 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. Turkey's trade ministry said that as one of the main S420MC chemical composition steel exporting countries to the EU, Turkey's export has been adversely affected by its measures and has started proceedings in the WTO."

The final heat treatment of quenched and tempered alloy steel, S420MC chemical composition is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.
