FACTORY AND PRODUCT PICTURE
ASTM1020 is a high quality carbon structural steel with high cold
deformation and plasticity.
The standard ASTM1020 is less than 1.35% of the carbon content of
20# steel in China. Besides the iron, carbon and the limit of silicon,
manganese, phosphorus, sulfur and other impurities, it does not
contain other alloy elements.The performance of carbon steel
depends mainly on carbon content.The carbon content increases,
the strength and hardness of the steel increases, and the plasticity,
toughness and weldability are reduced.Compared with other steel
classes, carbon steel is the earliest, low cost, wide range of
performance and the largest amount.
Features and scope of application:
The strength is slightly higher than 15 steel, rarely quenched, no
temper brittleness.Cold deformation of high plasticity, commonly
used for bending, rolling, flanging and hammer processing, such as
arch arc welding and resistance welding welding performance is
good, when welding thickness is small, strict shape or complex
shape partsprone to crack.Machined cold drawing or positive fire
state is better than annealing condition, which is generally used
for making small force and high toughness.,
Chemical composition:
S :≤0.050
P :≤0.040
Cr:≤0.25
Ni:≤0.25
Cu:≤0.25
Mechanical properties:
Tensile strength, b (MPa) : ≥ 410(42)
Yield strength: s (MPa) : ≥ 245(25)
The elongation is 5 (%) : ≥ 25.
The reduction rate of the cross section (%) : ≥ 55.
Hardness: no heat treatment, ≤156HB.
Sample size: sample size: 25mm.
Heat treatment specification and metallographic structure:
Heat treatment specification: fire, 910 ℃, air cooling.
Metallographic structure: ferrite + pearlite.
Our company mainly produces various specifications of cold drawn,
rolled precision steel tube,honed tube and SRB Tube, which
are widely used in such industries as hydro-cylinder, automobile,
engineering machinery, textile machinery, printing machinery, oil
drilling, etc.
