Steel Wire, Unpolished (Mill) Finish, Spring Temper, Precision Tolerance, 0.032" Diameter, 72" Length (Pack of 25)

The steel wire has a spring temper, an unpolished (mill) finish, and a precision tolerance, and meets American Society for Testing and Materials International ASTM A228 specifications. Steel wire is often used when strength is the main concern for an application. The spring temper is stiff and spring like, resisting bends and kinks until a large amount of force is applied.Steel is an iron alloy with carbon and other elements that modify the steel to achieve specific properties. In general, steels with higher carbon content have greater strength and hardness, while those with lower carbon content have more formability, weldability, and toughness. Carbon steels, which include most AISI-SAE grades in the 1000 range, are classified by their level of carbon content as low (below 0.3%), medium (0.3% to 0.6%) and high (0.6% and above). Alloy steels, which include AISI-SAE grades in the 1300 and 4000 ranges and above, incorporate elements such as chromium, molybdenum, and nickel to modify properties like corrosion resistance.Tensile strength, used to indicate a material’s overall strength, is the peak stress it can withstand before it breaks. Toughness describes the material's ability to absorb energy before breaking, while hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Formability indicates how easily the material can be permanently shaped.
