High Quality Carbon Structural Astm 1020 Steel - China

High-quality carbon structural steel: 1020

Executive standard: ASTM A29/A29M-04

●Characteristics and scope of application:

The strength is slightly higher than that of No.

15 steel, and it is rarely quenched and has no temper brittleness.

Cold deformation has high plasticity, and is generally used for bending, calendering, bending and hammer arching.

The welding performance of arc welding and contact welding is good.

The thickness is small during gas welding, and cracks are prone to occur on parts with strict shape requirements or complex shapes.

The machinability of the cold-drawn or normalized state is better than that of the annealed state, and it is generally used to manufacture low-stress and high-toughness requirements., ●Chemical composition:

Sulfur S: ≤0.050

Phosphorus P: ≤0.040

Chromium Cr: ≤0.25

Nickel Ni: ≤0.25

Copper Cu: ≤0.25

●Mechanical properties:

Tensile strength σb (MPa): ≥410(42)

Yield strength σs (MPa): ≥245(25)

Elongation δ5 (%): ≥25

Reduction of area ψ (%): ≥55

Hardness: without heat treatment, ≤156HB

Sample size: sample size 25mm

●Heat treatment specifications and metallographic structure:

Heat treatment specifications: normalizing, 910 ℃, air cooling.

Metallographic structure: ferrite + pearlite.

Delivered without heat treatment or heat treatment (annealed, normalized or high temperature tempered).

Those that require heat treatment should be specified in the contract, and those that are not specified will be delivered without heat treatment.
