A diluted sulfuric acid pickling bath is traditionally used, [6] but may be replaced with citric acid. Sheet steel that undergoes acid pickling will oxidize (rust) when exposed to atmospheric conditions of moderately high humidity. For this reason, a thin film of oil or similar waterproof coating is applied to create a barrier to moisture in ...
The Parkerizing process cannot be used to protect non-ferrous metals such as aluminium, brass, or copper but can be used for chemical polishing or etching instead. It similarly cannot be applied to steels containing a large amount of nickel, or on stainless steel. Passivation can be used for protecting other metals.
The EPS process produces scale-free steel strip which is interchangeable with acid-pickled steel strip, yet the EPS process entails lower capital and operating (variable) cost than an acid-pickling line of equivalent output. For this reason the EPS process is considered to be a direct replacement of acid pickling.

Hydrogen embrittlement is a complex process involving a number of distinct contributing micro-mechanisms, not all of which need to be present. The mechanisms include the formation of brittle hydrides , the creation of voids that can lead to high-pressure bubbles, enhanced decohesion at internal surfaces and localised plasticity at crack tips ...
What's more, the spices typically added during the pickling process, such as garlic and dill, are also rich in antioxidants, potentially reducing the risk of chronic diseases and promoting overall ...
