Product Description  

CS Type B carbon steel

CS Type B, is a kind of carbon steel.
Chemical composition (mass fraction) (%)
C: 0.09-0.15
Mn: 0.25-0.55
Si: ≦ 0.30
S: ≦ 0.050 (A grade), ≦ 0.045 (B grade)
P: ≦ 0.045
Deoxidation method: F, b, Z
Mechanical Properties
Tensile strength (σb / MPa): 335-450
Elongation (δ5 /%):
≧ 31 (a ≦ 16mm), ≧ 30 (a> 16-40mm)
≧ 29 (a> 40-60mm), ≧ 28 (a> 60-100mm)
≧ 27 (a> 100-150mm), ≧ 26 (a> 150mm)
Wherein a is the thickness or diameter of steel.
The bending performance
180 ° cold bending test
d = 0.5a (vertical) d = a (transverse) (B = 2a: 60mm), d = 1.5a (vertical) d = 2a (transverse) (B = 2a:> 60 ~ 100mm)
d = 2a (vertical) d = 2.5a (transverse) (B = 2a:> 100 ~ 200mm)
Where d is the diameter of the apex, B is the specimen width, a thickness or diameter of steel.
Impact test temperature: 20 ℃
V-impact energy (vertical) Ak / J: ≧ 27
