Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an alloy of iron that is resistant to rusting and corrosion. It contains iron with chromium and other elements such as molybdenum , carbon , nickel and nitrogen depending on its specific use and cost.
Properties. Alloy steels variously improve strength, hardness, toughness, wear resistance, corrosion resistance, hardenability, and hot hardness. To achieve these improved properties the metal may require specific heat treating, combined with strict cooling protocols. Although alloy steels have been made for centuries, their metallurgy was not ...
Weathering steel, often referred to by the genericised trademark COR-TEN steel and sometimes written without the hyphen as corten steel, is a group of steel alloys which were developed to eliminate the need for painting by forming a stable external layer of rust. U.S. Steel (USS) holds the registered trademark on the name COR-TEN. [1]
Beryllium copper (C17200 & C17300) is an age-hardening alloy that attains the highest strength of any copper base alloy. It may be age hardened after forming into springs, intricate forms, or complex shapes. It is valued for its elasticity, corrosion resistance, stability, conductivity, and low creep. Tempered beryllium copper is C17200 and ...
The steel's resistance to hydrogen embrittlement is critical in downhole environments where exposure to hydrogen sulfide (H₂S) can lead to material degradation and failure. [ 21 ] American musical instrument string producer Ernie Ball has made a specialist type of electric guitar string out of maraging steel, claiming that this alloy provides ...
Spring steel is a name given to a wide range of steels [1] used in the manufacture of different products, including swords, saw blades, springs and many more. These steels are generally low-alloy manganese, medium-carbon steel or high-carbon steel with a very high yield strength. This allows objects made of spring steel to return to their ...
Tempering (metallurgy) Differentially tempered steel. The various colors produced indicate the temperature the steel was heated to. Light straw indicates 204 °C (399 °F) and light blue indicates 337 °C (639 °F). [1][2] Tempering is a process of heat treating, which is used to increase the toughness of iron -based alloys.
Small springs can be wound from pre-hardened stock, while larger ones are made from annealed steel and hardened after manufacture. Some non-ferrous metals are also used, including phosphor bronze and titanium for parts requiring corrosion resistance, and low-resistance beryllium copper for springs carrying electric current.
