"Heart to sunshine, everything to prosperity"
China's fastener industry has shifted from producing generic, commercial-grade hardware to supplying high-precision, mission-critical special alloy fastening components. This transformation is driven by significant investments in domestic steel mill metallurgy and high-end thermal treatment infrastructure. Today, manufacturers like Beiersdorf Industrial Technology leverage localized supply chains for super alloys, enabling the production of high-tensile fasteners (up to 1900 MPa) and specialty bolts that meet stringent ASME, DIN, ISO, and classification society requirements.
By utilizing multi-station cold-heading machinery, precision CNC machining, and automated thread-rolling techniques, China's industrial exporters deliver consistent dimensional accuracy, reduced thread galling, and high fatigue resistance. This ensures reliable performance in demanding sectors like aerospace, offshore wind power, marine engineering, and petrochemical refining.
The performance of high-end bolts and studs depends heavily on raw material purity and precise heat treatment cycles. For instance, high-temperature fasteners operate in environments ranging from 400°C to 1200°C. Under these conditions, standard carbon steel undergoes creep deformation and rapid oxidation. Beiersdorf utilizes specialty materials, including:
International procurement managers frequently face challenges related to material traceability, certification compliance, and lead-time stability. Standardizing technical requirements, such as demanding EN 10204 3.1 or 3.2 material certificates, classification society approvals (such as DNV, ABS, CCS, Lloyd's Register), and detailed non-destructive testing (NDT) reports, mitigates compliance risks.
Beiersdorf addresses these challenges through integrated production control, maintaining a raw material reserve of 500 tons. This approach reduces delivery lead times for specialized alloy runs from the standard 60–90 days to just 15–30 days, enhancing supply chain resilience for critical project maintenance.

Beiersdorf (Shanghai) was founded in 2015 with a global perspective dedicated to providing professional fastener solutions. Fasteners, as basic mechanical components, play a critical role in global infrastructure. Our goal is to bridge domestic production capabilities with international engineering standards.
Read Full Article →For cryogenic applications (down to -270°C), fasteners must resist low-temperature embrittlement. Special austenitic stainless steel alloys and specific nickel-chromium grades are selected for their impact toughness at absolute zero. In high-temperature applications (up to 1200°C), materials must resist creep deformation, stress relaxation, and thermal oxidation. Under these conditions, superalloys like Inconel 718 or Cobalt-based formulations are specified because they maintain mechanical strength and resist oxidation under high thermal loads.
Hydrogen embrittlement is a risk for fasteners with tensile strengths exceeding 1000 MPa, particularly after electroplating. To mitigate this risk, our factory implements strict acid-pickling controls and requires baking (typically at 200°C for 4 to 24 hours depending on the material class) immediately after electroplating. This process diffuses hydrogen gas out of the steel crystal lattice before it can cause micro-cracking under stress.
We supply marine-grade fasteners (such as Duplex 2205, A4-80, A5-80, and high-strength alloy studs) with raw material and mill certificates according to EN 10204 3.1. Depending on project requirements, we can coordinate third-party inspections (EN 10204 3.2) and secure endorsements from major classification societies including CCS, DNV, ABS, and Lloyd's Register.
Thread rolling is a cold-forming process that plastically deforms the steel grains rather than cutting them. This maintains continuous grain lines along the profile of the thread, increasing shear strength, improving surface finish, and enhancing fatigue life. This process is essential for fasteners subjected to cyclic mechanical stress.
Beiersdorf is more than a supplier of special fasteners. We provide technical consultation and engineering guidance, assisting with raw material selection during early design stages, as well as installation and maintenance guidance for industrial projects.
