EN1A is a type of mild steel. It's got good properties for machining (free cutting) and can be formed by rolling or drawing. However the properties of the steel might have been changed by heat treatment so you can't just swap in components or make them yourself if you don't know what they are doing. If the part is to be used in a critical part of the car then you will need to ensure they are safe. http://www.oldengine.org/members/diesel/Tables/steel.htm
Reusing material means using the same materials again for another purpose instead of disposing of them. This helps to reduce waste and consumption of new resources.
The purpose of steam distillation in the extraction of essential oils is to separate the aromatic compounds from the plant material by using steam to gently heat and vaporize the oils, which are then condensed back into a liquid form for collection.

In legal contexts, it often refers to situations where false information is presented in a way that influences a contract or agreement.
A weighing bottle is used to accurately weigh small quantities of solid substances. It helps prevent contamination or loss of material during the weighing process.
Hardness is important in metallurgy because it determines the material's ability to resist deformation, wear, and scratching. It also affects the material's suitability for specific applications and its overall durability. By understanding the hardness of a metal, engineers can select the appropriate material for a particular purpose in industries such as automotive, construction, and manufacturing.
It is a convenient form of transportation.
The purpose of the automobile when it was first invented was to provide a faster and more convenient mode of transportation than horse-drawn carriages.
