Product Description  

Y45Ca cutting steel:
● Features and Scope:
Have excellent cutting performance, is suitable for high-speed machining, the normal processing time, processing speed of up to 150m / min or more, than 45 steel cutting speed increase more than doubled. After the heat treatment has good mechanical properties, generally used in the manufacture of the more important parts, such as gear shaft, spline shaft and tractor drive shaft, also commonly used in the automatic cutting machine high strength standard parts such as bolts, nuts?,
● Chemical Composition:
Carbon C: 0.42 ~ 0.50 "
Si Si: 0.20 ~ 0.40
Mn Mn: 0.60 ~ 0.90
Sulfur S: 0.04 ~ 0.08
Phosphorus P: ≤0.04
Chromium Cr: to allow the residual content ≤0.025
Ni: to allow the residual content ≤0.025
Cu: to allow the residual content ≤0.025; thermal processing time, ≤0.20
Calcium Ca: 0.002 ~ 0.006 (tolerance, + 0.002 -0.0005)
● Mechanical Properties:
Tensile strength σb (MPa) :( hot) 600 to 745; (cold drawn) steel thickness or diameter of 8 to 20 o'clock: 695 to 920;> 20 to 30: 655 - 855;> 30: 635 - 835 ; (heat treated) diameter>
Yield strength σs (MPa) :( heat treated) diameter> 16: ≥355
Elongation δ5 (%) :( hot rolled) ≥12; (rolled) ≥6.0; while (after heat treatment) diameter> 16: ≥16
Reduction of area ψ (%) :( hot rolled) ≥26; (when heat treated) diameter> 16: ≥40
When the impact energy Akv (J) :( heat treated) diameter> 16: ≥39
Hardness :( hot) ≤241HB; (cold drawing) 196 ~ 255HB
● Heat treatment and microstructure specifications:
Heat treatment specifications: 1) pull the sample blank (φ25) normalizing 830 ~ 850 ℃, insulation 30min. 2) Impact of the sample blank (φ15) quenching, quenching 840 ± 20 ℃, water-cooled, tempering recommend 600 ℃.
● Delivery status: hot-rolled or cold-drawn delivery, the delivery status should be specified in the contract.
