Which 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, deoiling cleaning and vacuum pump cleaning. They have different characteristics, and the formulas of the cleaning fluids they use are different. General cleaning agents include water-soluble resin cleaning fluids (there are two categories of crude oil organic solvents and solvents, which are not widely used) and water-based cleaning fluids (with bias) Alkali cleaning agents and surface active agents, etc.), in the specific cleaning process of quenching and tempering stainless steel castings, most of the following are used:

①Metal material cleaning agent, mostly used for cleaning before quenching and tempering treatment of stainless steel castings and organic chemical quenching and tempering treatment;

②3%-10%Sodium carbonate or sodium hydrogen radon cleaning solution, the temperature is controlled at80-100℃, it is mostly used to remove oil and salt residues of stainless steel castings after heat treatment.
