Thermal spraying and electroplating to improve wear resistance of stainless steel

1. thermal spraying Thermal spraying is the use of some heat source to heat the coating material to molten or semi-molten state, and with the help of flame flow and high-speed gas atomization, and promote these atomized particles spray to the surface of the matrix, deposition into a coating with a certain function. Thermal spraying …

Stainless steel tube authenticity identification method

Magnetic test is the simplest way to distinguish between annealed austenitic stainless steel and ferritic stainless steel. Austenitic stainless steel is a non-magnetic steel, but it will be slightly magnetic after cold working under high pressure. But pure chrome steel and low alloy steel are strong magnetic steel. Two, nitric acid point test stainless steel …
