Wuxi DongfutaiIn stock supply25#Round steel,25H-beam wholesale and retail,25#Round steel quality guaranteed. High quality, Daye, Great WallBenxi Steel, Zhongtian, etc.Produced by a large steel mill.

25High weldability and cold deformation plasticity, with certain strength and hardness. Good plasticity and toughness. Moderate machinability, poor hardenability and quenching. Good strength and toughness after quenching and tempering at low temperature. No tendency to temper brittleness. Generally used for manufacturing cold-pressed parts of medium and heavy machinery with low loads, small forgings, and small machined parts such as washers, shaft pins, bolts, nuts, etc.; after carburization or carbonitriding treatment, can be used to produce friction plates, piston pins, and non-critical gears; after normalization treatment, can be used as-20～475 Carbon steel forgings for pressure vessels at ℃. Weldments, hot-forged, and hot-pressed parts are carburized for use as wear-resistant components.

● Features and Application Scope:

High weldability and cold deformation plasticity, with certain strength and hardness. Good plasticity and toughness. Moderate machinability, poor hardenability and quenching. Good strength and toughness after tempering at low temperature. No tendency to temper brittleness. Generally used for manufacturing light-loaded cold stamping parts, small forgings, and small machined parts such as washers, shaft pins, bolts, nuts, etc., in heavy and medium-sized machinery; after carburizing or carbonitriding treatment, can be used to produce friction plates, piston pins, and unimportant gears; after normalizing treatment, can be used as -20～475 Forged steel for pressure vessels at °C. Weldments, hot forging, and hot stamped parts are carburized for use as wear-resistant components.
