Hangzhou EPG Co.,Ltd. , was launched in November, 1997. With its 5 wholly owned subsidiaries. We are aiming to meet the requires of the customers about the planet.. Keeping in brain that excellent provider is the important to cooperating with clients, we try to meet up with substantial high quality standards, supply competitive prices and guarantee prompt supply.
EPTT steel is an iron-carbon alloy with a carbon articles of .5718% to two.11%. Also named carbon steel. EPTTly includes a modest volume of silicon, manganese, sulfur, phosphorus. EPTTly, the larger the carbon content in carbon metal, the increased the hardness and the larger the energy, but the reduced the plasticity.
EPTT structural metal
Manufacturer: Example Q235-A middotF, which signifies sigmas=235MPa.
Model notes: Q is the generate power A high quality grade (with ABCD grade four), F boiling steel.
Characteristics: minimal price tag and excellent method efficiency (this kind of as weldability and chilly formability).
Application: EPTT engineering framework and EPTT mechanical areas. For case in point, Q235 can create bolts, nuts, pins, hooks and considerably less EPTTant mechanical areas, as properly as screw metal, EPT steel, steel bars in developing structures.
EPT-quality carbon structural steel
EPTmarks: Instance 45, 65Mn, 08F.
Manufacturer annotation: straight expresses the carbon content material of the metallic in tens of hundreds.
Application: Non-alloy steels used to manufacture EPTTant mechanical areas are EPTTly utilized following warmth treatment method.
Common steel grades and uses:
08F, minimal mass fraction of carbon, great plasticity, low toughness, utilised for stamping areas this sort of as vehicle and instrument shell
20, good plasticity and weldability, employed for components with reduced toughness demands and carburized components, this sort of as hoods, welded containers, little shafts, nuts, washers and carburized EPTs
forty five, 40Mn, with good complete mechanical homes following quenching and tempering, used for mechanical parts with better tension, this kind of as EPTs, connecting rods, EPTT device spindles, etc.
sixty, 65Mn metal has large toughness it is used to manufacture different EPTs, rims of locomotive wheels, and lower-velocity wheels.
EPTT device steel
Manufacturer: For instance, T12 steel signifies carbon tool steel with Wc=1.two%.
Grade notes: T additionally the steel carbon material in thousand.
Functions: It beEPTTs to eutectoid metal and hypereutectoid metal, with large power and hardness, and great put on resistance. It is appropriate for manufacturing a variety of low-velocity chopping resources.
Typical metal grades and utilizes:
T7, T8: Manufacture parts that demand a certain affect and call for toughness. These kinds of as sledgehammer, punch, chisel, woodworking resources, scissors.
T9, T10, T11: Manufacture resources with minimal affect and substantial hardness and dress in resistance. This sort of as taps, modest drills, dies, and hand saw blades.
T12, T13: Make instruments that are not impacted. Such as information, scrapers, razors, measuring tools.
Brand name: For instance, ZG200-four hundred, implies forged metal with sigmas=200MPa and sigmab=400MPa.
Overall performance: EPTT overall performance is even worse than solid iron, but mechanical qualities are EPT than forged iron.
Software: It is mainly utilised to manufacture much more EPTTant mechanical parts with complex shapes and higher mechanical functionality requirements, and it is hard to sort by forging and other approaches in the process, this sort of as car EPTT shells, couplers and couplings of rolling stock.
