The execution standards for carbon steel machined parts need to be determined based on the specific application scenario, material grade, and manufacturing process.
General Standards for Carbon Steel Turned Parts
EN 10277-3:2008: Applicable to various free-machining carbon steels (such as 1.0726/35S20, 1.0722/10SPb20, 1.0715/11SMn30, etc.), specifying their chemical composition, mechanical properties, and machining characteristics; widely used in European and export products.
ASTM A29 / SAE J403: Applicable to hot-rolled and cold-drawn supply conditions of medium and high carbon steels (such as 1070 steel) in American standards, covering machining methods such as turning and forging.
GB/T 33161-2016 "Carburized Steel for Automotive Bearings": Applicable to carburized steel turned parts for key automotive components, specifying chemical composition, residual elements, inspection rules, etc.
T/SSEA 0016-2018 "Carbon Bearing Steel for Passenger Car Wheels": Designed for high-precision machined parts such as wheel bearings, it employs an ultra-pure smelting process with strict dimensional and compositional control.
