Steel is an alloy of iron and carbon. Carbon is the primary alloying element, and its content in the steel is between 0.002% and 2.1% by weight. Additional elements are also present in steel: manganese, phosphorus, sulfur, silicon, and traces of oxygen, nitrogen and aluminium. Alloying elements intentionally added to modify the characteristics of steel include: manganese, nickel, chromium, molybdenum, boron, titanium, vanadium and niobium.
In the context of quality management, "steel" refers to a type of alloy that is composed primarily of iron and carbon, with other elements such as nickel, chromium, and manganese added for specific properties and applications. Steel is widely used in many industries and applications due to its strength, durability, and resistance to corrosion.
Examples of steel in a quality management context include:
-
Structural steel - steel used in construction and building, such as beams, columns, and girders.
-
Steel components - components used in machinery and equipment, such as gears, bearings, and shafts.
-
Steel plates and sheets - steel used in manufacturing and fabrication, such as automotive body panels, ship hulls, and containers.
-
Steel pipes - steel used in pipelines, plumbing, and water distribution systems.
-
Steel wire - steel used in electrical conductors, springs, and ropes.
Quality management for steel products and materials may include processes such as material selection, manufacturing, and testing to ensure that the products meet the desired quality standards and specifications. This may include processes such as visual inspection, non-destructive testing, and destructive testing to verify the strength, durability, and resistance to corrosion of the steel. The goal is to ensure that the products are safe, reliable, and fit for their intended use.
