Hot Coiled Spring

Hot coil spring (hot wound spring), also known as large spring, because the spring diameter is very large, hot coil diameter to 16-200mm, the production process using hot roll process. Giant spring is easy to twist after heating forming, less resilience, after quenching and tempering. Spring used in national defense, marine, aerospace, railway, nuclear power, wind power, thermal power, construction machinery, mining machinery, construction machinery, elevators steel plant and power plants and other equipment.
Shuangyuan produce hot coil spring with wire diameter from 15mm to 90mm.
Good quality.
Surface treatment can be: powder coating, painting, plating, Dacromet, etc. or according to user requirements.
Material:
Alloy spring steel: 60Si2MnA, 50CrVA, 4Cr13, 60Si2CrA,
load capacity: 500N - 1 million N
