In modern high-precision industries, fasteners are subjected to extreme dynamic conditions, massive structural preloads, and highly corrosive chemical environments. While design engineers prioritize major tension components such as high-strength bolts and studs, the critical role played by the accompanying washers is often underestimated. Industrial washers are not merely simple spacers; they are essential structural interfaces. By distributing clamp loads evenly over surfaces, protecting substrates from galling, and mitigating galvanic corrosion, premium-grade washers ensure long-term torque retention and structural security.
At Beiersdorf Industrial Technology (Shanghai) Co., Ltd., we utilize advanced metallurgy and precision manufacturing processes to produce stainless steel washers that excel in severe-service scenarios. From cryogenic sub-zero environments (-270°C) to intense petrochemical operating parameters and extreme high-temperature applications (up to 1200°C), our material science guarantees zero-defect operation under fluctuating thermal stresses.
Standard commercial washers typically employ simple grade 304 (A2) or 316 (A4) stainless steels. However, critical applications in ocean engineering, marine propulsion, semiconductor chambers, and aerospace demand far more sophisticated microstructures. Beiersdorf designs and exports washers in high-alloy and super-austenitic steels to prevent localized corrosion phenomena:
We have formulated the most stringent sampling inspection system, utilizing advanced optical scanners and non-destructive testing methodologies, to strive to achieve zero defects for the products out of our factory.
Innovation drives our core capabilities. At present, our entire group has more than 100 utility model patented products and eight invention patented products, pushing the limits of high-performance metallurgy.
We currently operate nearly 100,000 product models, maintaining 500 tons of special raw materials and 10,000 tons of finished stainless steel standard parts in stock for rapid global deployment.
Beiersdorf Industrial Technology (Shanghai) Co., Ltd. was established in 2015 and is located in Shanghai, China. It is an enterprise mainly engaged in the design, engineering, and manufacturing of special fasteners and ultra-high precision components. Over the past decade, we have established a strong reputation as a premium global supplier, providing industrial clients with mechanical solutions that withstand high stresses and critical environments.

Industrial washers serve as the first line of defense in maintaining initial installation preloads and preventing galvanic corrosion between complex metal interfaces. At Beiersdorf, our products are engineered for several macro-industrial sectors:
Operating environment: Constant seawater submersion, high salinity, mechanical vibration. Our Marine-certified washers (including A4-80, A5-80, Duplex 2205, and D8-80) are engineered to prevent pitting, maintaining clamp pressure on vessel shafts, propulsion plates, dock winches, and offshore oil rigs.
Operating environment: Extremely high operating temperatures, acidic environments containing sulfur, dynamic pressure loops. We supply nickel-alloy and super-stainless steel washers designed to resist stress corrosion cracking (SCC) at high operating temperatures up to 1200℃.
Operating environment: Constant vibrational stress, fluctuating mechanical loads, environmental exposure. High-tensile washers and locking washer systems maintain constant tightness under rail cars and structural bridge systems, minimizing infrastructure maintenance intervals.
Standard carbon steel washers lose tensile strength and develop surface oxidation rapidly in humid or chemically aggressive settings. By contrast, Beiersdorf’s custom stainless washers, containing precise percentages of Chromium (18-20%), Nickel (8-12%), and Molybdenum (2-3%), create a self-healing passivation surface layer. This passive oxide layer provides continuous protection, ensuring the clamp force remains within engineering specifications throughout the equipment's operational lifespan.
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.
