Full-threaded rod for pipe flanges (DIN 975) and high-strength studs for the chemical industry (35CrMoA).

Carbon Steel: Typically used for general applications.

Stainless Steel: For environments where corrosion resistance is required.

Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

Material properties: 35CrMoA is an alloy structural steel with good overall mechanical properties and low temperature impact toughness. Its working temperature can be as high as 500 ° C, low temperature up to -100 ° C. This material has a high static strength and high fatigue strength, good hardenability, not easy to overheat, quenching deformation is small, medium machinability . Chemical composition: 35CrMoA chemical composition includes carbon (C: 0.32 ~ 0.40%), silicon (Si: 0.17 ~ 0.37%), manganese (Mn: 0.40 ~ 0.70%), phosphorus (P ≤ 0.030%), sulfur (S ≤ 0.030%), chromium (Cr: 0.80 ~ 1.10%), molybdenum (Mo: 0.15 ~ 0.25%). Mechanical properties: 35CrMoA yield strength ≥ 835 MPa, tensile strength ≥ 980 MPa, elongation ≥ 12%, sectional shrinkage ≥ 45%, impact absorption energy ≥ 63 J . Heat treatment: 35CrMoA is usually quenched and tempered to improve its mechanical properties.

Scope of Application

Chemical industry: In the construction of chemical plants, 35CrMoA all-thread studs are used for connecting and fixing pipes, pressure vessels and heat exchangers due to their good mechanical properties and corrosion resistance. Pipe flanges: DIN 975 full thread studs are commonly used for pipe flange connections to provide a stable and reliable fastening force. High-strength connections: Due to their high-strength properties, Grade 8.8 and 10.9 studs are suitable for applications that require high loads and vibrations, such as heavy machinery, bridges and steel structures.
