Carbon steel machined parts are characterized by their excellent machinability, good mechanical properties, and high cost-effectiveness, making them one of the most widely used metal parts in machinery manufacturing.
Excellent machinability, suitable for mass production. Carbon steel (especially low and medium carbon steel) has low cutting resistance and good chip breaking properties during turning, is less prone to severe built-up edge, and produces a high surface finish. Sulfur-containing free-cutting steels (such as Y12 and 1.0726) further improve chip breaking and tool life by adding sulfur to form MnS inclusions, making them particularly suitable for efficient continuous machining on automatic lathes.
Moderate material strength and toughness, meeting the needs of various working conditions.
Low carbon steel (such as 1020 steel): Good plasticity and strong weldability, suitable for manufacturing structural parts with relatively low stress;
Medium carbon steel (such as 45# steel): After quenching and tempering, it combines high strength and good toughness, widely used in key components such as gears and shafts;
High carbon steel (such as T10): High hardness and good wear resistance, suitable for special applications such as cutting tools and molds.
Excellent weldability and formability. Especially low-carbon steel, it possesses excellent weldability, suitable for various processes such as arc welding and gas shielded welding. Welded joints exhibit high strength and good toughness, facilitating subsequent assembly and structural integration.
High standardization and stable supply chain. The carbon steel grade system is comprehensive (e.g., AISI, EN standards), with clearly defined chemical composition and mechanical property specifications for commonly used materials from 1020 to 1045, facilitating design selection, quality control, and bulk procurement.
Supports multiple surface treatments to adapt to different environments. Surface treatments such as galvanizing, blackening, and phosphating can be selected according to the application scenario to improve rust resistance or lubrication performance and extend service life.
