There are many brands of stainless steel on the market, but the types are no more than 201/202, 301/302, 304, 316 these, but among them, 316 stainless steel has a strong corrosion resistance and high temperature resistance, can be used in harsh conditions, but the price is relatively common 304 stainless steel per kilogram to more than 10 expensive. Therefore, in the industrial field, stainless steel is still very important to remove rust, oil and debris.
Stainless steel stains and corrosion are mainly caused by
First, dust pollution
The dust attached to the surface of stainless steel mainly from suspended particles in the air and dust generated during mechanical processing and logistics handling.
Second, oil stains
The oil on the surface of stainless steel is mainly due to the need to add lubricating oil for lubrication and cooling in the stamping process. After stamping is completed, some oil stains will be attached to the surface of the workpiece.
Third, rust spots
Air oxidation after the chemical reaction.
Which cleaning agent should be used to clean stainless steel products?
In fact, most cleaners are “specialty areas” and different types of stains require different cleaners. As a common steel in the market, 304 stainless steel is much less resistant to corrosion and heat than 316 stainless steel. Therefore, alkaline and acidic cleaners are not suitable for cleaning. It is recommended to use neutral oil cleaner for cleaning.
To sum up, the type of cleaner to be used should be determined according to the actual situation. It is not necessary to choose a certain type of cleaning agent, it is recommended to use with cleaning equipment such as ultrasonic cleaning machine to achieve better cleaning results.
