The main function of boron in 09CUPCRNI-B steel elements and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.

"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 09CUPCRNI-B steel elements 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.
