Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, and rust or scale from ferrous metals, copper, precious metals and aluminium alloys. [1] A solution called pickle liquor , which usually contains acid , is used to remove the surface impurities.
Eco pickled surface (EPS) is a process applied to hot rolled sheet steel to remove all surface oxides and clean the steel surface.Steel which has undergone the EPS process acquires a high degree of resistance to subsequent development of surface oxide (rust), so long as it does not come into direct contact with moisture.
Various testing methods are available to determine the passivation (or passive state) of stainless steel. The most common methods for validating the passivity of a part is some combination of high humidity and heat for a period of time, intended to induce rusting. Electro-chemical testers can also be utilized to commercially verify passivation.
Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc, or manganese phosphates to improve corrosion resistance or lubrication or as a foundation for subsequent coatings or painting. [1] [2] [3] It is one of the most common types of conversion coating.
Sheet metal forming, thread manufacturing, and other industrial operations may include moving parts, or contact surfaces made of stainless steel, aluminium, titanium, and other metals whose natural development of an external oxide layer through passivation increases their corrosion resistance but renders them particularly susceptible to galling ...
The cutting torch can be integrated into a machine to perform precision cutting operations. In multi-axis machines, the movement of the axes is powered by electric motors and synchronized to guide the torch and the pipe being cut along a programmed path, resulting in the desired cutting profile.
