Application: |
carbon structural steel |
cases Q235-A - F, denoted sigma S is equal to or larger than 235mpa |
q is the yield strength a quality level (there are four ABCD), f boiling steel |
low price, process performance (such as welding and cold forming of excellent. |
general engineering structure and general mechanical parts. Such as Q235 can produce bolt, a nut, a pin, a hook and less important mechanical parts and building structure of screw steel, steel, steel, etc. |
high quality carbon structural steel |
45, 65Mn, 08F |
the direct representation of the amount of carbon content of the ten million |
08F carbon mass fraction of low plasticity is good, the strength is low, for stamping parts such as cars and instrument shell; 20, plasticity and good weldability, strength for less demanding parts and carburized parts, such as hood, welded vessels, a small shaft, nuts, washers and carburized gear. |
applications: the manufacture of important mechanical parts of the non alloy steel, generally used after heat treatment. |
carbon tool steel |
T12 Steel said carbon tool steel Wc=1.2% |
T and metal containing carbon amount of scores of thousands |
genus eutectoid and hypereutectoid steel, high strength and hardness, wear resistance for in various manufacturing low-speed cutting tool |
T7, T8: Production under impact toughness requirements of parts. Such as sledgehammer, punch, chisel, woodworking tools, scissors, T9, T10, T11: manufacturing impact smaller requirements high hardness high abrasion of tools. |
cast steel |
such as ZG200-400, said: S = 200MPa, B = Sigma 400MPa cast steel. |
|
casting performance than iron is poor, but the mechanical performance is better than cast iron; more important application |
mainly used in the manufacture of complex shape, high mechanical properties, and in the process and difficult to use methods such as forging forming mechanical parts, such as car gearbox shell, locomotive car coupler and coupling and so on. |
