Japan's stainless steel industry overall scale is small, the export of 304 stainless steel water pipe production and consumption has a significant drive. On the contrary, China's stainless steel production scale is huge, accounting for more than 50% in the world, at the same time 304 stainless steel pipe production lack of raw material support, relying on large-scale direct export support 304 stainless steel pipe production and consumption to maintain in a platform period is not realistic.

And because of the global steel overcapacity, Southeast Asian countries 304 stainless steel pipe capacity is increasing, in recent years, Japan's export share is also decreasing, stainless steel exports have been declining for six consecutive years. China's manufacturing industry has a sufficiently large domestic market and the most complete industrial system in the world. Some industries, such as household appliances, have strong international competitiveness. Construction machinery products represented by excavators have also realized international expansion from import substitution.
