The European Iron and Steel Industry Union (Eurofer) has sent a letter to the president of the European Commission, asking the Commission to review the existing trade safeguard measures immediately, proposing to reduce the steel import quota by 75% within six months to help the European steel industry cope with the current difficult situation; For imported steel exceeding the quota, the tariff rate can be reduced to less than 25%. Europe has also proposed restrictions on size list of 05CUPCRNI and so on steel imports related to crisis and safety.

Oxygen (O) is a harmful element in steel such as size list of 05CUPCRNI. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.
