Small size 10# wire, cold drawn steel wire, standard parts wire, 10# steel wire

Grade: No. 10 steel

Implementation standard: GB/T699-1999

No. 10 steel has good plasticity and toughness, and is easy to be formed by cold and hot processing. It has good cutting performance after normalizing or cold working, excellent weldability, no temper brittleness, and poor hardenability and hardenability.

Manufacturing parts that require low stress and high toughness, such as automobile bodies, containers, deep-drawn vessels, pipes, gaskets, etc., can be used for cold rolling, cold stamping, cold heading, cold bending, hot rolling and other forming processes. It can also be used as carburized parts and carbonitrided parts with low core strength.

10# Steel wire chemical composition: It is a steel named according to its carbon content, which is generally 0.07% - 0.13%. Compared with S10C steel wire, its chemical composition regulations are relatively less stringent, focusing mainly on the key indicator of carbon content. The range requirements for other elements such as manganese, silicon, etc. may not be as detailed as S10C.

Implementation standards: In China, 10# steel wire mainly implements the GB/T 699-2015 "High-Quality Carbon Structural Steel" standard. This standard focuses on stipulating the basic quality requirements, test methods and other contents of steel to meet the needs of domestic industrial production.

Strength and toughness: The strength and toughness indicators are similar to S10C steel wire, but due to differences in chemical composition and production process details, the specific values and performance stability may be slightly different. The strength and toughness of 10# steel wire can also meet general machining and use requirements.

Processing performance: The processing performance is also good, and it can be processed by cold drawing, cold heading, etc. However, in some cases where processing accuracy and surface quality are extremely high, S10C steel wire may have more advantages.

Application areas: also used in machinery manufacturing and construction industries. In machinery manufacturing, it can be used to make some ordinary connectors and structural parts; in the construction industry, it can be used to make simple reinforcements, hanging nets, etc., and is used in some occasions where performance requirements are not particularly demanding.
