SAE 1020 20 Gauge Carbon Steel Bar Low Carbon Steel Round Rod
SAE 1020 Specification
(1) Characteristics The steel belongs to high quality low carbon
steel, cold extrusion, carburizing hardened steel. The steel has
low strength, good toughness, plasticity and weldability. Tensile
strength of 253-500mpa, elongation ≥24%.
The properties of 20 steel are similar to those of 15 steel, but
the strength is slightly higher. Application: suitable for
manufacturing cars, tractors and general machinery manufacturing
industry in the construction of small and medium-sized carburizing
carburizing parts, such as car brake shoe, lever shaft,
transmission fork, transmission passive gear and tractor camshaft,
equalizer shaft, equalizer inside and outside bushing; In hot
rolling or normalizing state used for manufacturing force is not
large, but requires high toughness of various mechanical parts; In
heavy and medium machinery manufacturing, such as forged or pressed
ties, carabiners, levers, sleeves, fixtures, etc. Used in steam
turbine and boiler manufacturing industry for pressure ≤6N/ square,
temperature ≤450℃ in the work of non-corrosive medium pipes,
flanges, header and various fasteners; Used for making crosshead,
piston and other castings on railway and locomotive.
Normalizing can promote the spheroidization of the steel, refine
the massive pre-eutectoid ferrite, and improve the cutting
performance of the blank less than 160HBS.
The process route of the steel die parts is: blanking → forging die
blank → annealing → mechanical rough machining → cold extrusion
forming → recrystallization annealing → mechanical finishing →
carburizing → quenching and tempering → grinding and polishing →
assembly.
(2) Supply state and hardness without heat treatment, hardness
≤156HBS.
