Product Description
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 greater the carbon content in carbon steel, the higher the hardness and the higher the power, but the reduce the plasticity.
species
EPTT structural metal
Manufacturer: Example Q235-A middotF, which means sigmas=235MPa.
Manufacturer notes: Q is the yield strength A quality grade (with ABCD quality 4), F boiling steel.
Attributes: minimal cost and outstanding procedure efficiency (such as weldability and chilly formability).
Software: EPTT engineering structure and EPTT mechanical elements. For illustration, Q235 can produce bolts, nuts, pins, hooks and less EPTTant mechanical components, as nicely as screw steel, EPT steel, metal bars in building structures.
EPT-quality carbon structural steel
EPTmarks: Instance 45, 65Mn, 08F.
Manufacturer annotation: right expresses the carbon articles of the steel in tens of hundreds.
Application: Non-alloy steels utilized to manufacture EPTTant mechanical parts are EPTTly utilized following warmth remedy.
Typical metal grades and uses:
08F, lower mass fraction of carbon, good plasticity, reduced strength, utilised for stamping parts these kinds of as auto and instrument shell
20, excellent plasticity and weldability, employed for areas with minimal strength requirements and carburized parts, such as hoods, welded containers, little shafts, nuts, washers and carburized EPTs
forty five, 40Mn, with excellent extensive mechanical properties after quenching and tempering, utilised for mechanical elements with greater tension, these kinds of as EPTs, connecting rods, EPTT resource spindles, etc.
60, 65Mn metal has higher toughness it is utilized to manufacture numerous EPTs, rims of locomotive wheels, and reduced-pace wheels.
EPTT device steel
Brand: For instance, T12 metal signifies carbon device steel with Wc=1.2%.
Quality notes: T in addition the metallic carbon content material in thousand.
Features: It beEPTTs to eutectoid steel and hypereutectoid metal, with higher toughness and hardness, and very good wear resistance. It is suited for producing various reduced-speed reducing equipment.
Typical metal grades and uses:
T7, T8: Manufacture elements that demand a specified impact and require toughness. This kind of as sledgehammer, punch, chisel, woodworking tools, scissors.
T9, T10, T11: Manufacture equipment with minimal influence and higher hardness and put on resistance. This sort of as taps, little drills, dies, and hand saw blades.
T12, T13: JCEP instruments that are not impacted. Such as information, scrapers, razors, measuring instruments.
Solid steel
Manufacturer: For instance, ZG200-400, indicates forged metal with sigmas=200MPa and sigmab=400MPa.
Overall performance: EPTT functionality is even worse than forged iron, but mechanical homes are EPT than cast iron.
Application: It is mainly used to manufacture much more EPTTant mechanical elements with complicated styles and large mechanical performance requirements, and it is difficult to form by forging and other techniques in the method, such as car EPTT shells, couplers and couplings of rolling inventory.
