What is Chinese shipbuilding steel CCS D36 HS code

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and Chinese shipbuilding steel CCS D36 pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.

API 2H gr50 is carburized steel, which is usually low carbon steel with carbon content of 0.15% - 0.24%, and is used for offshore platform structure. API 2H gr50 steel is suitable for surface carburizing and hardening treatment, with good workability, small deformation and good fatigue resistance. Chinese shipbuilding steel CCS D36, API 2H gr50 steel is used for making hull, offshore oil production platform, platform pipe joint and other structural parts.

In the first quarter of 2020, the output of EU steel pipe industry decreased by 13.3% year-on-year, but it is considered to be flexible due to its close connection with the Chinese shipbuilding steel CCS D36 construction industry. However, demand for large welded pipes is expected to remain weak in the oil and gas industry. In 2020, the steel consumption of steel pipe industry will account for 13% of EU Chinese shipbuilding steel CCS D36 steel consumption market. Uestf predicts that in 2020, the output of steel pipe industry will continue the downward trend of 2019, with a year-on-year decrease of 19.4%, and a rebound of 9.8% in 2021.

In general, the global manufacturing industry has been seriously impacted by the epidemic, and the foreign epidemic is still in the outbreak period, and its Chinese shipbuilding steel CCS D36 demand recovery still has some time. However, the domestic epidemic situation has come to an end. In addition, the state has repeatedly stressed that the development of traditional infrastructure and new infrastructure needs a lot of steel. And now the return to work is getting better. As of March 20, the return rate of key projects is 89.1%, and the return rate of 11000 key projects in China is nearly 90%.
