Item Description

EPTT steel is an iron-carbon alloy with a carbon material of .5718% to two.eleven%. Also known as carbon steel. EPTTly consists of a small quantity of silicon, manganese, sulfur, phosphorus. EPTTly, the higher the carbon material in carbon steel, the greater the hardness and the greater the toughness, but the reduce the plasticity.
species
EPTT structural metal
Model: Case in point Q235-A middotF, which implies sigmas=235MPa.
Brand name notes: Q is the produce power A quality quality (with ABCD grade four), F boiling metal.
Characteristics: lower cost and excellent procedure efficiency (such as weldability and cold formability).
Software: EPTT engineering framework and EPTT mechanical components. For instance, Q235 can generate bolts, nuts, pins, hooks and significantly less EPTTant mechanical elements, as well as screw steel, EPT steel, metal bars in building buildings.
EPT-good quality carbon structural steel
EPTmarks: Case in point forty five, 65Mn, 08F.
Model annotation: straight expresses the carbon content material of the metal in tens of 1000’s.
Application: Non-alloy steels utilized to manufacture EPTTant mechanical parts are EPTTly used after heat treatment method.
Frequent steel grades and employs:
08F, minimal mass portion of carbon, very good plasticity, minimal power, utilized for stamping elements such as automobile and instrument shell
twenty, excellent plasticity and weldability, utilized for components with reduced strength needs and carburized elements, this kind of as hoods, welded containers, small shafts, nuts, washers and carburized EPTs
45, 40Mn, with excellent comprehensive mechanical houses after quenching and tempering, utilised for mechanical components with better tension, such as EPTs, connecting rods, EPTT device spindles, and so on.
sixty, 65Mn metal has substantial power it is employed to manufacture numerous EPTs, rims of locomotive wheels, and low-velocity wheels.
EPTT instrument steel
Brand: For illustration, T12 metal indicates carbon instrument metal with Wc=1.two%.
Quality notes: T in addition the metallic carbon articles in thousand.
Attributes: It beEPTTs to eutectoid steel and hypereutectoid steel, with large power and hardness, and very good put on resistance. It is suited for producing numerous low-velocity slicing equipment.
Typical steel grades and utilizes:
T7, T8: Manufacture areas that need a specific influence and call for toughness. This sort of as sledgehammer, punch, chisel, woodworking resources, scissors.
T9, T10, T11: Manufacture instruments with lower influence and higher hardness and put on resistance. Such as faucets, tiny drills, dies, and hand saw blades.
T12, T13: Make tools that are not impacted. Such as files, scrapers, razors, measuring resources.
Forged steel
Model: For instance, ZG200-400, implies solid metal with sigmas=200MPa and sigmab=400MPa.
Overall performance: EPTT overall performance is even worse than forged iron, but mechanical homes are EPT than forged iron.
Application: It is largely employed to manufacture more EPTTant mechanical parts with complex designs and substantial mechanical efficiency specifications, and it is challenging to sort by forging and other techniques in the approach, such as vehicle EPTT shells, couplers and couplings of rolling inventory.
