In November 2025, Shanghai TOTEM Machinery Co., Ltd. was invited to participate in Metal-Expo’2025, the 31st International Industrial Exhibition, held at CEC Expoforum in St. Petersburg, Russia. As one of the most influential and professional exhibitions in the global metals and metallurgy industry,
Read More →Why do polar ships need higher-standard thrust shafts? In marine propulsion systems, the thrust shaft is a key component that transmits power from the main engine to the propeller, directly affecting the reliability of the vessel’s navigation.

Read More →Selecting reciprocating compressor cylinder material is vital for safety and life-cycle cost. This article compares three cast families: iron (grey/ductile), steel (carbon/low-alloy), and stainless (austenitic CF8M/CF3M, martensitic 17-4PH). It examines strength, hardness, thermal conductivity, expansion, self-lubrication, corrosion resistance, weldability, and failure modes (wear, corrosion, cracking, creep).
