Chinese steel swords make their appearance from the 5th century BC Warring States period, although earlier iron swords are also known from the Zhou dynasty. The Chinese Dao (刀 pinyin dāo) is single-edged, sometimes translated as sabre or broadsword, and the Jian (劍 pinyin jiàn) double edged.
Stainless steel is a popular class of material for knife blades because it resists corrosion and is easy to maintain. However, it is not impervious to corrosion or rust. For a steel to be considered stainless it must have a Chromium content of at least 10.5%. [24] 154CM / ATS-34 steels. These two steels are practically identical in composition ...
Where iron and steel are plentiful this method is frequently used as it requires less time. In places and times where iron and steel have been more rare and valuable stock removal has not been used except as part of the finishing process. In most techniques, the basic materials, generally iron and/or steel, are shaped into a bar or billet first.
Iron alloys are most broadly divided by their carbon content: cast iron has 2–4% carbon impurities; wrought iron oxidizes away most of its carbon, to less than 0.1%. The much more valuable steel has a delicately intermediate carbon fraction, and its material properties range according to the carbon percentage: high carbon steel is stronger but more brittle than low carbon steel.

Chinese iron swords made their first appearance in the later part of the Western Zhou dynasty, but iron and steel swords were not widely used until the 3rd century BC Han dynasty. [17] The Chinese dao (刀 pinyin dāo) is single-edged, sometimes translated as sabre or broadsword, and the jian (劍 or 剑 pinyin jiàn) is double-edged.
The macuahuitl had many drawbacks in combat versus European steel swords. Despite being sharper, prismatic obsidian is also considerably more brittle than steel; obsidian blades of the type used on the macuahuitl tended to shatter on impact with other obsidian blades, steel swords or plate armour.
A bloomery is a type of metallurgical furnace once used widely for smelting iron from its oxides. The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a bloom. The mix of slag and iron in the bloom, termed sponge iron, is usually consolidated and further forged into ...
