Shanghai Mei Shen Industrial Co., Ltd., established in 1999, stands as a titan in the specialty alloy and high-performance material manufacturing sector. With over two decades of rigorous research and development, we have evolved into a fully integrated production powerhouse. Our commitment to excellence is reflected in our specialized production of Hastelloy C-22 (Alloy C-22) rods, which are engineered to meet the world’s most demanding corrosion resistance standards.
Hastelloy C-22, also known as Alloy C-22, is a versatile nickel-chromium-molybdenum-tungsten alloy. It is specifically designed to resist a broad range of severe corrosive environments. Unlike other nickel alloys, C-22 provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking across both oxidizing and reducing media. For global industrial buyers, the C-22 rod is the "gold standard" for longevity in chemical processing.
The global demand for Hastelloy C-22 rods is surging, driven by the expansion of high-tech industries such as semiconductor manufacturing, pharmaceutical synthesis, and green energy (hydrogen production). In the USA and Europe, C-22 is preferred for FGD (Flue Gas Desulfurization) systems and nuclear fuel reprocessing due to its unmatched stability in aggressive acid mixtures.
We are seeing a massive shift toward "Total Corrosion Control" where engineers opt for C-22 over standard stainless steel to reduce maintenance lifecycle costs. Procurement specialists are increasingly looking for Chinese factories that can provide high-purity melts (VIM/VAR) with rapid lead times to replace aging infrastructure in the Middle East's desalination and petrochemical sectors.
The production plant of steel wire rope is located in Jiangsu Province, with an annual output of stainless steel wire rope, various specifications of smooth steel wire rope, galvanized steel wire rope, plastic coated steel wire rope, compacts steel wire rope, special steel wire rope for rotary excavator, special steel wire rope for elevator, non-rotating series of Silu-Wallington-type steel wire rope, carbon spring steel wire, and other hardware rigging products.
The products are widely used in construction machinery, bridge construction, ocean engineering, port lifting, coal mine, water conservancy engineering and other industries of lifting, binding and traction equipment. It is the largest and most complete steel wire rope production base in China.
Used in reactor vessels, heat exchangers, and piping systems handling acetic acid, formic acid, and brine solutions. Its resistance to wet chlorine makes it indispensable.
Ideal for sanitary fittings and multi-purpose reactors where cross-contamination must be prevented and equipment must withstand aggressive cleaning agents.
Critical for municipal and industrial wastewater treatment plants, particularly in hazardous waste incineration and flue gas scrubbers.
Optimized for reducing bending stress, abrasion resistance and increased stability against radial pressures.
Special purpose wire rope with steel core and EIP level application for modern drilling rig manufacturing.
Includes single strand, 6 strand, and multi-strand wire rope designed for Marine engineering and sealed applications.
Every Hastelloy C-22 rod comes with a comprehensive Mill Test Certificate (MTC) conforming to EN 10204 3.1, ensuring precise chemical compositions (Ni, Cr, Mo, W levels).
Equipped with state-of-the-art centerless grinding and cold-drawing machines, we provide rods with h8-h11 tolerances and mirror-like surface finishes.
Located near Shanghai port, we offer unrivaled logistics for bulk global shipments, reducing transit times and inventory costs for international distributors.
While Hastelloy C-276 has been the industry standard for decades, Hastelloy C-22 offers significantly better overall corrosion resistance. Its higher chromium content (22% vs 16%) provides superior protection against oxidizing chemicals like nitric acid and ferric chlorides. For engineers designing new chemical plants, C-22 is the proactive choice for long-term reliability. As a leading supplier, we provide C-22 rods in sizes from 1.5mm up to 300mm to accommodate every engineering requirement.
Today's procurement managers face challenges including price volatility and material shortages. Our factory mitigates these risks by maintaining a robust raw material buffer and utilizing AI-driven production scheduling. We support wholesale buyers with customized lengths, heat treatments (Solution Annealed), and specialized testing including Ultrasonic Testing (UT) and PMI (Positive Material Identification).
