Description
S60C, SAE1060 spring steel
Standard:
● Characteristics and scope of application:
It is a high-strength medium carbon steel with high surface hardness and strength after treatment, but the plasticity and toughness are poor, the cutting performance is medium, the weldability and the hardenability are poor, and the water quenching has a tendency to form cracks. Generally used after normalizing or quenching, it is used for parts requiring higher strength and wear resistance or elasticity, dynamic load and impact load, such as gears, rims, flat springs, crankshafts, etc.
● Chemical composition:
Carbon C: 0.52 ~ 0.60"
Silicon Si: 0.17 ~ 0.37
Manganese Mn: 0.50 ~ 0.80
Sulfur S: ≤0.035
P: ≤0.035
Chromium Cr: ≤0.25
Nickel Ni: ≤0.25
Copper Cu: ≤0.25
● Mechanical properties:
Tensile strength σb (MPa) : ≥645(66)
Yield strength σs (MPa) : ≥380(39)
Elongation δ5 (%) : ≥13
Section shrinkage ratio ψ (%) : ≥35
Hardness: no heat treatment,≤255HB; Annealed steel,≤217HB
Sample size: 25mm
● Heat treatment specifications and metallographic structure:
Heat treatment specification: normalizing,820℃; Quenching,820℃; Temper,600℃.
Metallographic structure: sorbite.
Delivery condition: Delivery in a condition of no heat treatment or heat treatment (annealing, normalizing or high temperature tempering). Where delivery in heat treatment condition is required, it shall be indicated in the contract, and if not indicated, delivery shall be made without heat treatment.
