Porca de parafuso hexagonal OEM forjada em liga de aço AISI 4140 com revestimento eletrónico para equipamento ferroviário

Product name:OEM die forged alloy steel AISI 4140 e-coating hexagon head screw nut for railway equipment.

Nuts are the parts screwed together with bolts or screws for fastening. They are an original that must be used in all production and manufacturing machinery. Our common nuts are those with national standards, ISO,GB,JIS,DIN,BS,ANSI,etc.A wide range of applications including boat building, RV manufacturing, industrial fabrications and more.

Perfil da empresa:

Baoding Longway company have excellent knowledge of metal forging, associated processes and assemblies. And long term focus on the production of large forging parts, production technologies include metal forging processing,heat treatment,mechanical processingetc. At present, it has formed a complete production process accessories chain.

Detalhes do produto:

Forged components are commonly found at points of shock and stress such as wheel spindles, kingpins, axle beams and shafts, torsion bars, ball studs, idler arms, pitman arms and steering arms. In forging, the metal is pounded and deformed, but the grain flow remains unbroken, allowing it to retain its strength.

Die forged hexagon head screw nuts applicaiton: mechanical and structural assembly, construction and in frastructure, automotive components, aerospace engineering, mining and excavation.

Heating: the steel is heated to a high temperature, making it malleable and ready for shaping.

Die forging:

1. Initial shaping: the heated steel is placed between die molds and subjected to high pressure to form the rough shape of the hexagon head screw nut.
2. Precision forging: further forging steps refine the shape and ensure precise dimensions and tolerances.
3. Heat treatment: the forged parts undergo heat treatment processes such as quenching and tempering to enhance mechanical properties like hardness and strength.

Machining and finishing: Final machining processes ensure accurate threading and surface finish, and additional treatments (such as galvanizing or coating) may be applied for corrosion resistance.
