The origin of the name "Damascus Steel" is contentious. Islamic scholars al-Kindi (full name Abu Ya'qub ibn Ishaq al-Kindi, circa 800 CE – 873 CE) and al-Biruni (full name Abu al-Rayhan Muhammad ibn Ahmad al-Biruni, circa 973 CE – 1048 CE) both wrote about swords and steel made for swords, based on their surface appearance, geographical location of production or forging, or the name of the ...
Rust scale forming and flaking off from a steel bar heated to its forging temperature of 1200°C. Rapid oxidation occurs when heated steel is exposed to air. Rust is a general name for a complex of oxides and hydroxides of iron, [4] which occur when iron or some alloys that contain iron are exposed to oxygen and moisture for a long period of ...
Legends of wootz steel and Damascus swords aroused the curiosity of the European scientific community from the 17th to the 19th century. The use of high- carbon alloys was little known in Europe [ 20 ] previously and thus the research into wootz steel played an important role in the development of modern English, French and Russian metallurgy .

Stainless steel, also known as "inox steel" does not stain, corrode, or rust as easily as ordinary steel. Pierre Berthier, a Frenchman, was the first to notice the rust-resistant properties of mixing chromium with alloys in 1821, which led to new metal treating and metallurgy processes, and eventually the creation of usable stainless steel.
Acid etching darkens the 1080 plain carbon steel more than it does the 15N20 low alloy nickel steel, producing alternating bands of light and dark on the surface. Pattern welding developed out of the necessarily complex process of making blades that were both hard and tough from the erratic and unsuitable output from early iron smelting in ...
Flame cleaning, also known as flame gouging, [1] is the process of cleaning a structural steel surface by passing an intensely hot oxyacetylene flame over it. Mill scale and rust are removed by the reducing effect of the flame and the action of the heat, leaving the surface in a condition suitable for wire brushing and painting.
Stainless steel is good for low maintenance. Wrought iron is used for garden furniture. It is heavy, which is useful on windy days. It needs much care, and can easily rust and corrode if not waterproofed. Aluminum is more common than steel furniture, mostly because it does not rust, although it oxidizes, turning into a chalky white.
