DIN C55 is the German standard DIN EN10083-2:1996 in the steel grades, equivalent to China's national standard GB/T699-1999
"High carbon structural steel" in the "55 steel", its relevant information is as follows:
1. C55 chemical composition (%)
C (0.52~0.60), Si (0.17~0.37), Mn (0.50~0.80), Cr (less than 0.25), Ni (less than 0.30), Cu (less than 0.25), according to the high quality steel, high quality steel, super high quality steel, sulfur and phosphorus were respectively 0.035, 0.030, 0.025
2. C55 mechanical properties
The tensile strength is not less than 645MPa; lower yield strength is not less than 380MPa; elongation: 13%; section shrinkage rate: = 35%
C55 steel is a German brand, but C55 steel is a general designation, there are a few small numbers, such as C55K, C55W.
C55W, the steel is flat or rolling plate of a special steel plastic mold, plastic mold, high strength carbon steel, the steel cutting medium, cold plastic deformation, poor welding, heat treatment when no temper brittleness, but the hardenability is low, and the water quench a cracking tendency, good hardenability.
BEBON STEEL is specialized in exporting Material C55 Sheets and plates. We can offer various sizes and shapes of C55 .Welcome to visit our factory.
