Explore our top-tier selection of industrial bolts, high-precision machined parts, and advanced specialty material components engineered to withstand extreme pressures and environments.
Beiersdorf Industrial Technology (Shanghai) Co., Ltd., established in 2015 and based in China's industrial epicenter, Shanghai, is a premier designer, manufacturer, and global exporter of high-end specialty fasteners and ultra-high-precision components. In a global economy defined by automation, advanced robotics, and challenging environments, standard fasteners often fall short. We bridge this critical structural gap. Our engineering mission centers on the manufacturing of heavy-duty, high-integrity joints capable of performing flawlessly under intense mechanical, chemical, and thermal pressures.
Our corporate DNA is anchored in three key pillars that guarantee absolute reliability, engineering depth, and logistical agility for international enterprises.
We have formulated the most stringent sampling and non-destructive testing (NDT) inspection systems. Every single batch of high-precision parts undergoes meticulous geometric and mechanical verification to ensure zero defects before leaving our factory.
Our R&D division has pushed the boundaries of metallurgical science and structural engineering, yielding more than 100 utility model patented products and eight pioneering invention patents for specialized fastening challenges.
We maintain a massive, digitally managed inventory consisting of nearly 100,000 distinct product models. This includes 500 tons of raw exotic materials in stock and 10,000 tons of finished stainless steel standard parts ready for immediate international dispatch.
Our diverse portfolio of specialized fasteners provides critical reliability across demanding aerospace, medical, electronics, and maritime platforms.
Perfectly suited for MRI medical diagnostics, precision physics equipment, and aerospace electronics where electromagnetic fields must remain completely undisturbed.
Including Super Stainless Steel, Titanium Alloys, Nickel-based superalloys, and Hastelloy grades engineered for harsh chemical exposure.
Lightweight, non-conductive, and highly corrosion-resistant components designed for electronics, plating lines, and cleanroom setups.
Fully certified maritime and offshore construction fasteners built to strictly conform with elite global classification criteria.
Crafted from premium special raw materials, featuring ultra-high tensile strength and fatigue limit properties for critical spring elements.
Ultra-high-precision components fabricated to micrometer-level tolerances for electronic, optical, and semiconductor machinery.
Exhibiting superb ductile toughness down to cryogenic temperatures (-270℃), preventing brittle fractures in liquid gas pipelines.
Retaining excellent yield strength and scaling resistance in service temperatures as high as 1200℃, ideal for combustion chambers.
From maritime deep-sea pipelines to extreme temperature power generation plants, our fasteners are trusted in the most severe operation fields.
Our special fasteners are widely used in the field of shipbuilding and oceanography engineering, specifically in the manufacture of special ships, marine propulsion, marine accessories, yacht manufacturing, offshore oil drilling platforms, submarine pipelines, offshore wind power, underwater lifeboats, port machinery, dock construction, etc. These special fasteners mainly include A4-80, A5-80, D8-80, D6-70, 2205, L7, 40CrNiMoA, 718, EN14399 steel structure connection pair, classification society certificate fasteners, etc.

Industrial machinery operates at extreme limits. Standard carbon steel fasteners quickly fail when exposed to cryogenic liquids like liquefied hydrogen (-253°C) or the searing heat of turbine exhaust gases (up to 1000°C). Selecting the correct alloy is not merely about preventing rust; it is about managing the crystalline structures of metals. Austenitic alloys, titanium grades, and nickel-based superalloys (such as Inconel 718 and Inconel 625) prevent brittle transitions at low temperatures and resist creep deformation under massive tensile loads at high temperatures.
For instance, in marine and subsea environments, chloride-induced stress corrosion cracking (SCC) is a major threat to structural integrity. Fasteners made of Duplex 2205 (UNS S32205) or super duplex steels provide a balanced two-phase microstructure of austenite and ferrite, doubling the mechanical strength and providing excellent resistance to pitting and crevice corrosion compared to traditional 316 stainless steels.
As tensile strength reaches 1200 MPa and goes up to 1900 MPa, the threat of Hydrogen Embrittlement (HE) increases. HE occurs when atomic hydrogen diffuses into the metal lattice, causing sub-critical crack propagation and catastrophic, sudden failures under static loads. At Beiersdorf, we mitigate this risk through precise metallurgical control, utilizing raw materials with optimized chemical compositions and low impurity levels.
In modern electronic equipment manufacturing and lithography chambers, dimensional accuracy must be maintained within micron ranges. Our high-precision machined parts undergo rigorous multi-axis CNC operations, precision grinding, and polishing. High vacuum environments require fasteners that do not cause outgassing. This is achieved by utilizing vacuum-arc remelted (VAR) alloys, ultra-clean surface treatments, and specialized cleanroom packaging.
Furthermore, non-magnetic fasteners are crucial for medical devices like Magnetic Resonance Imaging (MRI) scanners and electron microscopes. The use of premium titanium (such as Grade 5 / Ti-6Al-4V) or specific copper-nickel alloys ensures zero interference with high-strength magnetic fields, while maintaining the necessary mechanical clamping force.
Heavy infrastructure projects, bridge networks, and maritime vessels rely on certified fastener connections. Our manufacturing lines align with standard organizations worldwide, producing EN 14399 structural preloading bolt assemblies, ASTM A320 cryogenic bolts, and ASTM A193 high-temperature studs. Complete material traceability is maintained through Mill Test Reports (MTR) according to EN 10204 3.1/3.2, ensuring that safety-critical applications are backed by transparent testing records.
Get answers to the most common technical questions concerning metallurgy, fastener choice, and design compliance.
For extreme cryogenic environments (such as liquid helium transport at -269℃ or superconducting magnets), standard ferritic steels undergo a ductile-to-brittle transition, making them highly prone to cracking. We recommend austenitic stainless steels with high nickel and manganese content (such as Grade 316, 310, or XM-19) and high-performance superalloys like Inconel 718 or A286. These materials preserve high impact energy absorption and mechanical ductility even near absolute zero.
Our zero defects goal is achieved through our integrated Hash Detection system. This quality control protocol combines automated optical sorting machines (which verify thread pitch, shank straightness, and head dimensions at speeds up to 500 parts per minute) with non-destructive ultrasonic and magnetic particle testing. For high-spec fasteners, we also perform destructive tensile, yield, and hardness testing on random samples from each heat batch.
Inconel bolts (such as Inconel 718 or 625) should be selected when service temperatures exceed 550°C, or in highly oxidizing and corrosive atmospheres (like chemical reactors or marine gas turbines). Stainless steel 316 loses its mechanical strength and undergoes severe scaling and creep deformation above 600°C, whereas Inconel maintains high yield strengths, resists thermal oxidation, and prevents creep failure at temperatures up to 980°C.
We provide full material traceability certified by major global classification societies, including China Classification Society (CCS), DNV, ABS, and Lloyd's Register. Our marine fasteners comply with standards such as A4-80, Duplex 2205, and ASTM A320 L7. Every batch is supplied with EN 10204 3.1 material test certificates documenting chemical composition, mechanical properties, and non-destructive testing results.
Yes, our production plant in Shanghai features advanced multi-axis CNC Swiss machining centers capable of maintaining tolerances within ±0.005 mm. We regularly manufacture custom micro-screws, specialized shoulder bolts, and complex fasteners with custom thread profiles for high-end optical sensors, semiconductor manufacturing equipment, and surgical instruments.
