Abstract


Low carbon steel can be applied in various fields of manufacturing industry, pipes, machine parts. The problem that is often faced is that corrosion often occurs, resulting in changes in the properties and characteristics of the steel material, requiring very high costs for prevention and maintenance of equipment due to corrosion. The use of ultrasonic waves to measure the rate of corrosion can identify defects and damage to the material. This study used a completely randomized design method with variations in immersion time of 6 hours, 7 hours, 8 hours, 9 hours, 10 hours and variations in hydrochloric acid concentration of 4%, 5%, 6% while the specimen dimensions were 30 mm in diameter and specimen thickness 20 mm. From the research results, it was found that the best corrosion rates at 10 hours of hydrochloric acid concentration were 0.2233 mmpy, 0.2664 mmpy and 0.3294 mmpy.

Keywords
