How to prevent rust from the machined steel parts?

1, If the machined steel parts are not properly maintained, rust will not be avoided. The rust preventive oil needs to be correctly selected and used.

2, Machined steel parts will use cutting fluid, cleaning agent, and then apply anti rust oil. If the cutting fluid or cleaning agent on the machined steel parts is not rinsed, and the antirust oil is used directly, and the antirust oil is used without replacement function, if it is a low price antirust oil, due to the production of non-standard base oil and high acid value, it is very prone to emulsification and deterioration, the final result is the porphyritic rust formed on the surface of the machined steel parts, and the color gradually deepens. Therefore, it is necessary to increase the rinsing process in Machining Steel Parts and choose to use antirust oil with permutation performance.

3, Human sweat is a colorless, transparent or yellowish liquid with salty taste and weak acid. Its pH value is 5 ~ 6. In addition to containing sodium, potassium, calcium and magnesium salts, it also contains a small amount of organic acids such as urea, lactic acid and citric acid. When sweat is contacted with machined steel parts, a sweat film will form on the surface of the machined steel parts. Sweat film will cause electrochemical effect on machined steel parts and corrode it. Human sweating is inevitable. To prevent rusting from hand sweating, the producer should bring gloves, finger sleeve, or use special tools to take machined steel parts. Do not touch the machined steel parts by hand.
