Corrosion Causes and Anticorrosion Methods for Aluminum Alloy in High-speed Trains
The body and hook-beam structure of high-speed trains are manufactured using aluminum alloy, known for its advantages such as low density, high strength-to-weight ratio, good corrosion resistance, and excellent low-temperature performance. By replacing traditional steel ...Read more -
Cold rolled steel plate why pickling passivation
Cold rolled steel plate is rolled out on the basis of hot rolled coil, generally speaking, is hot rolled → pickling passivation → cold rolled such a process. Although in the process because of rolling will also make the steel plate temperature, but still called cold roll...Read more -
Introduction to the polishing process of high clean stainless steel pipe
The surface finish of high-clean stainless steel piping system plays a very important role in the safe production of food and drug. Good surface finish has the characteristics of cleanability, reduction of microbial growth, corrosion resistance, removal of metal impuriti...Read more -
Analysis and Solutions to Common Issues in Electrolytic Polishing
1.Why are there spots or small areas on the surface that appear unpolished after electro-polishing? Analysis: Incomplete oil removal before polishing, resulting in residual oil traces on the surface. 2.Why do gray-black patches appear on the surface after polishing? Anal...Read more -
The principle of pitting corrosion of stainless steel and how to prevent pitting corrosion
Pitting corrosion is also called small hole corrosion, pitting or pitting. It is a form of corrosion damage in which most of the surface of the metal does not corrode or corrodes very slightly, but corrosion holes appear in local places and develop deeper. Some pits exi...Read more -
The difference between austenitic and ferritic stainless steel
The main distinction between austenitic stainless steel and ferritic stainless steel lies in their respective structures and properties. Austenitic stainless steel is an organization that remains stable only at temperatures higher than 727°C. It exhibits good plasticity ...Read more -
