Carbon steel woks, however, tend to be more difficult to season than those made of cast-iron ('seasoning', or carbonizing the cooking surface of a wok, is required to prevent foods from sticking and to remove metallic tastes and odors). [2] Carbon steel woks vary widely in price, style, and quality, which is based on ply and forming technique.
In Chinese, characters for the elements are the last officially created and recognized characters in the Chinese writing system.Unlike characters for unofficial varieties of Chinese (e.g., written Cantonese) or other now-defunct ad hoc characters (e.g., those by the Empress Wu), the names for the elements are official, consistent, and taught (with Mandarin pronunciation) to every Chinese and ...
Carbon steel is often divided into two main categories: low-carbon steel and high-carbon steel. It may also contain other elements, such as manganese, phosphorus, sulfur, and silicon, which can affect its properties. Carbon steel can be easily machined and welded, making it versatile for various applications.
Carbon steel: An alloy of iron and approximately 1% carbon. Most carbon steel chef's knives are simple carbon iron alloys without exotic additions such as chromium or vanadium. Carbon steel blades are both easier to sharpen than ordinary stainless steel and usually hold an edge longer, but are vulnerable to rust and stains. Some professional ...
The Chinese of the Warring States period (403–221 BC) had quench-hardened steel, [27] while Chinese of the Han dynasty (202 BC—AD 220) created steel by melting together wrought iron with cast iron, thus producing a carbon-intermediate steel by the 1st century AD.
Chinese metallurgy was widely practiced during the Middle Ages; during the 11th century, the growth of the iron industry caused vast deforestation due to the use of charcoal in the smelting process. [54] [55] To remedy the problem of deforestation, the Song Chinese discovered how to produce coke from bituminous coal as a substitute for charcoal.

A UNS-derived system known as ISC (in Chinese 统一数字代号, literally "unified numeric designator") is used in China in parallel to the composition-based nomenclature. [6] Individual grades may receive the same number (e.g. S31603), a slightly different number (e.g. S30400/S30408, S17400/S17440), or a totally different one (e.g. S20200 ...
