China has taken a series of measures to counteract U.S. tariffs
Starting from April 4, China has launched a series of countermeasures in response to U.S. actions. The Tariff Commission of the State Council, the Ministry of Commerce, and the General Administration of Customs of China have successively announced multiple countermeasures against the United States. These measures include imposing a 34% tariff on all U.S.-origin imported goods, filing a case against the U.S. at the World Trade Organization (WTO) dispute settlement mechanism, adding multiple U.S. entities to the export control list, implementing export controls on medium and heavy rare earth-related items, and suspending the qualifications of six U.S. companies for exporting to China.

Will the Tariff War Trigger the Next Great Depression? The 'Doomsday Asset' List from Lessons of Blood and Tears
Introduction: The Collision between Historical Ghosts and Reality In 1930, the U.S. Smoot-Hawley Tariff Act ignited a global trade war, which directly led to the collapse of international trade and the soaring of the unemployment rate to 25%, ultimately triggering the Great Depression. Nearly a hundred years later, in 2025, the Trump administration restarted a 25% vehicle tariff, targeting China's industrial chain. Canada threatened a "power cut counterattack", reigniting the global trade powder keg once again.

Production process of stainless steel seamless pipes
In the production process of stainless steel seamless pipes, a series of complex procedures need to be carried out. These procedures include: starting from round steel, going through re-inspection, peeling, blanking, centering, heating, piercing, pickling, facing, inspection and grinding, cold rolling (cold drawing), degreasing, heat treatment, straightening, pipe cutting (fixed length), re-pickling/passivation, until the final finished product inspection (including eddy current, ultrasonic, hydrostatic pressure) and packaging for storage. Each link is crucial to ensure the quality and performance of the final product.

Bend test of metallic materials
Bend test is one of the basic methods for testing the mechanical properties of materials, mainly used to determine the mechanical properties of materials subjected to bending loads. In the bend test, one side of the specimen is unidirectional tensile, the other side is unidirectional compression, the maximum positive stress appears on the surface of the specimen, so it is very sensitive to surface defects. This feature makes the bend test is often used to check the surface defects of the material, such as carburisation or surface quenching layer quality. bend test is mainly used to determine the brittle and low plasticity materials (such as cast iron, high carbon steel, tool steel, etc.) bend strength, and reflect the plasticity index of the deflection. For brittle materials, because of the eccentricity sensitivity, the use of tensile testing is not easy to accurately determine its mechanical properties indicators, so the bend test is often used to determine its bend strength, and the use of comparative method to determine the deformation of the material’s deformation capacity.

Nickel Based Alloy
With the continuous progress of science and technology, stainless steel is used more and more widely. However, in some special harsh environments (such as ocean, nuclear power, aviation, energy, petrochemical, food, etc.),ordinary stainless steel is no longer competent. In these special fields,special stainless steel is indispensable and irreplaceable. In recent years, with the rapid development of economy and the continuous improvement of the industrial level, more and more projects need stainless steel with superior performance, and nickel-based alloy is one of the representative steel grades.

Introduction and Classification of Stainless Steel (2)
In addition to the ferritic, austenitic and martensitic stainless steels mentioned in the previous article, there are also ferritic-austenitic duplex stainless steels and precipitation hardening stainless steels with more complex metallographic structures. The microstructure determines the material properties. Duplex stainless steels and precipitation hardening stainless steels have other advantages due to the change of structure, which also enriches the types of stainless steels.
