EPTT metal is an iron-carbon alloy with a carbon content material of .5718% to two.11%. Also named carbon metal. EPTTly includes a tiny amount of silicon, manganese, sulfur, phosphorus. EPTTly, the larger the carbon material in carbon metal, the increased the hardness and the larger the energy, but the decrease the plasticity.
EPTT structural metal
Brand: Case in point Q235-A middotF, which means sigmas=235MPa.
Brand name notes: Q is the produce strength A quality quality (with ABCD quality four), F boiling metal.
Features: reduced price and outstanding procedure efficiency (this kind of as weldability and cold formability).
Software: EPTT engineering framework and EPTT mechanical parts. For instance, Q235 can make bolts, nuts, pins, hooks and considerably less EPTTant mechanical components, as properly as screw metal, EPT steel, steel bars in developing structures.
EPT-quality carbon structural metal
EPTmarks: Illustration forty five, 65Mn, 08F.
Brand annotation: right expresses the carbon content material of the metallic in tens of countless numbers.
Application: Non-alloy steels utilized to manufacture EPTTant mechanical areas are EPTTly utilized soon after warmth treatment method.
Common metal grades and employs:
08F, lower mass portion of carbon, excellent plasticity, low toughness, utilized for stamping areas this kind of as car and instrument shell
20, very good plasticity and weldability, used for components with lower energy specifications and carburized elements, this sort of as hoods, welded containers, little shafts, nuts, washers and carburized EPTs
45, 40Mn, with great extensive mechanical qualities right after quenching and tempering, used for mechanical areas with increased stress, such as EPTs, connecting rods, EPTT resource spindles, and so on.
sixty, 65Mn steel has substantial toughness it is employed to manufacture a variety of EPTs, rims of locomotive wheels, and low-pace wheels.
EPTT instrument metal
Model: For example, T12 metal means carbon instrument metal with Wc=1.two%.
Grade notes: T additionally the steel carbon content in thousand.
Attributes: It beEPTTs to eutectoid steel and hypereutectoid metal, with substantial power and hardness, and great use resistance. It is suited for manufacturing various reduced-pace cutting instruments.
Widespread steel grades and uses:
T7, T8: Manufacture elements that call for a specified affect and require toughness. These kinds of as sledgehammer, punch, chisel, woodworking tools, scissors.
T9, T10, T11: Manufacture tools with minimal influence and substantial hardness and use resistance. This kind of as faucets, little drills, dies, and hand saw blades.
T12, T13: Make equipment that are not impacted. This sort of as data files, scrapers, razors, measuring tools.
Model: For instance, ZG200-four hundred, means forged metal with sigmas=200MPa and sigmab=400MPa.
Overall performance: EPTT efficiency is worse than cast iron, but mechanical properties are EPT than forged iron.
Software: It is primarily used to manufacture a lot more EPTTant mechanical parts with complex shapes and large mechanical performance requirements, and it is challenging to kind by forging and other strategies in the process, such as car EPTT shells, couplers and couplings of rolling stock.
