45# steel plate
1. Introduction to 45# steel plate:
45# is a high-quality carbon structural steel, corresponding to Japanese standard S45C, American standard: 1045, and European standard C45. It is characterized by higher strength and deformation resistance than ordinary A3 steel.
2. 45# steel plate implementation standard: GB/T 711-2017
3. 45# steel plate delivery status: hot rolled; normalized, annealed, high temperature tempered or quenched and tempered
4. 45# reference corresponding steel number:
Chinese GB standard steel number 45; Japanese JIS standard steel number S45C/S48C; European brand number: C45, material number: 1.0503; American AISI/SAE standard steel number 1045; International Organization for Standardization ISO standard steel number C45E4.
5. Chemical composition of 45# steel:
Grade | C | Si | Mn | P | S | Cr | Ni | Cu |
45# | 0.42-0.50 | 0.17-0.37 | 0.50-0.80 | ≤0.035 | ≤0.030 | ≤0.20 | ≤0.30 | ≤0.25 |
6. Mechanical properties of 45# steel:
Grade | Tension strength /MPA | Elongation after break A% |
45# | ≥600 | ≥17 |
7. Surface quality of 45# steel plate
Generally speaking, the surface of 45# steel plate should be flat and smooth, without obvious defects, cracks, inclusions, etc.
8. Size, shape, weight and allowable deviation of 45# steel plate
The size, shape, weight and allowable deviation of the 45# steel plate comply with the requirements of GB/T709.
