Item Description

EPTT steel is an iron-carbon alloy with a carbon material of .5718% to two.11%. Also referred to as carbon steel. EPTTly contains a tiny volume of silicon, manganese, sulfur, phosphorus. EPTTly, the larger the carbon articles in carbon metal, the higher the hardness and the larger the strength, but the lower the plasticity.
species
EPTT structural steel
Manufacturer: Example Q235-A middotF, which means sigmas=235MPa.
Brand notes: Q is the generate strength A top quality quality (with ABCD grade 4), F boiling metal.
Attributes: low price tag and superb approach overall performance (this kind of as weldability and cold formability).
Software: EPTT engineering composition and EPTT mechanical elements. For instance, Q235 can create bolts, nuts, pins, hooks and considerably less EPTTant mechanical areas, as well as screw steel, EPT steel, steel bars in creating constructions.
EPT-quality carbon structural metal
EPTmarks: Example 45, 65Mn, 08F.
Brand annotation: straight expresses the carbon content material of the steel in tens of hundreds.
Software: Non-alloy steels employed to manufacture EPTTant mechanical components are EPTTly utilized following warmth treatment method.
Frequent steel grades and utilizes:
08F, lower mass portion of carbon, great plasticity, minimal strength, employed for stamping parts such as auto and instrument shell
20, very good plasticity and weldability, utilised for parts with low power specifications and carburized elements, such as hoods, welded containers, modest shafts, nuts, washers and carburized EPTs
forty five, 40Mn, with great extensive mechanical qualities following quenching and tempering, utilised for mechanical elements with better pressure, these kinds of as EPTs, connecting rods, EPTT tool spindles, and so on.
60, 65Mn metal has substantial toughness it is utilised to manufacture various EPTs, rims of locomotive wheels, and reduced-pace wheels.
EPTT instrument metal
Manufacturer: For instance, T12 metal signifies carbon resource metal with Wc=one.two%.
Quality notes: T additionally the steel carbon material in thousand.
Attributes: It beEPTTs to eutectoid metal and hypereutectoid steel, with higher strength and hardness, and very good put on resistance. It is suitable for manufacturing a variety of minimal-velocity chopping instruments.
Widespread metal grades and utilizes:
T7, T8: Manufacture parts that call for a certain affect and require toughness. Such as sledgehammer, punch, chisel, woodworking equipment, scissors.
T9, T10, T11: Manufacture tools with lower influence and large hardness and dress in resistance. Such as taps, small drills, dies, and hand observed blades.
T12, T13: Make equipment that are not impacted. These kinds of as documents, scrapers, razors, measuring equipment.
Cast metal
Brand: For case in point, ZG200-400, signifies forged metal with sigmas=200MPa and sigmab=400MPa.
Functionality: EPTT efficiency is worse than solid iron, but mechanical houses are EPT than cast iron.
Software: It is primarily utilised to manufacture far more EPTTant mechanical elements with complicated designs and large mechanical performance requirements, and it is difficult to kind by forging and other strategies in the method, such as automobile EPTT shells, couplers and couplings of rolling stock.
