The use of Stainless Steel 304 material has excellent physical properties and can be easily adjusted to meet requirements with the help of welding. With welding joints made of Stainless Steel 304, this study will create a specimen that will later be used as a reference for the durability of the weld joints made. The electrode used is of the same type as the material being used. In this study, t…
Steel is a very vital need, this can be seen from the increasing number of construction machine/equipment components made of steel. This study aims to determine the effect of acid solution on the corrosion rate of quenched stainless steel (AISI 304). This study uses experimental research methods. This research was conducted for 240 hours or 10 days, the specimens used were 5 specimens in specim…
Corrosion is damage that occurs to metal with a brownish color marked on the metal surface, one of the factors for corrosion is the environment. To slow down the occurrence of corrosion is done by giving heat treatment, one of which is normalizing heat treatment. This research is an experimental study with the aim of knowing the effect of normalizing heat treatment on the corrosion rate of low …
in modern times like today, humans are increasingly spoiled with various tools that make work easeir. However, this iron based equipment often corrodes, resulting in losses both in terms of user safety and econimic value. Corrosion itself cannot be stopped but the corrosion rate can be inhibited by various techniques, one of which is the quenching method. This study aims to determine the effect…
Korosi celah merupakan korosi yang terjadinya akibat adanya perbedaan konsentrasi oksigen didalam celah maupun diluar celah. Bentuk korosi ini sering kita jumpai dicelah sambungan pipa, boiler, turbin dan komponen-komponen mesin. Penelitian ini dilakukan untuk melihat pengaruh jarak celah terhadap laju korosi baja karbon sedang dan aluminium 1100 dengan variasi jarak celah 0 mm, 0,21 mm dan 0,4…
This study aims to determine the effect of electrode variations on malleable steel plates using a variation of the corrosive environment in descriptive methods. The technique of collecting data is done by documenting the workpiece that has been welded by electrodes variations that immersed with varitions of corrosive solution using digital microscope until 15 days. The results of this study sho…
Korosi adalah suatu keadaan yang bersifat merusak pada hampir semua logam. Istilah karat sebenarnya digunakan untuk korosi pada besi, dimana besi pada jaman dahulu merupakan logam yang paling banyak dimanfaatkan, sedangkan korosi merupakan gejala destruktif yang mempengaruhi hampir semua logam, korosi merupakan permasalahan yang selalu terjadi pada peralatan produksi minyak d…
