Customs statistics show that in the first two months of 2020 year, Tianjin's imports and exports to the EU, South Korea, Japan, the United States and other traditional trading partners declined, and imports and exports to ASEAN were 12.7 billion yuan, an increase of 7.8%, accounting for 12.8%. Among Tianjin's main trading partners, The only company that keeps growing is Tianjin's second largest trading partner. During the same period, Tianjin's imports and exports to the countries along the “Belt and Road” were 25.3 billion yuan, an increase of 6.2%, accounting for 25.5% of the city ’s total foreign trade import and export value, and an increase of 3.9% compared to the same period last year.

Hydrogen (H) is the most harmful element in general steel such as 09CUPTIRE-A steel supplier. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
