What kinds of formulas are used for surface cleaning of stainless steel castings? How to choose?
The cleaning of stainless steel castings is divided into general cleaning, ultrasonic cleaning, degreasing cleaning and vacuum cleaning. They have their own characteristics, and the formulas of the cleaning fluids they use are different. General cleaning agents include solvent-based cleaning fluids (with petroleum solvents and organic solvents, which are not widely used) and water-based cleaning fluids (with alkaline cleaning agents) And surfactants, etc.). In the actual cleaning process of heat-treated stainless steel castings, the following are mostly used:
①Metal cleaning agent, mostly used for cleaning before heat treatment and chemical heat treatment of stainless steel castings;
② 3%-10% sodium carbonate or sodium hydride cleaning fluid, temperature controlled at 80-100℃, is mostly used for degreasing and salt residue cleaning of stainless steel castings after quenching.
