Usually there are two kinds of seamless steel (carbon steel) pickling method, as follows:
1. Sulfate: diluted to a concentration of about 20%, was heated to 60-65 degrees, typically 20-30 min wash;
2. Hydrochloride: Similarly to a concentration of about 20%, direct pickling temperature, typically 20-30 min wash;
After pickling (descaling to date), should immediately wash with water immediately and treatment, rust, then, but also for passivation.
