904L Stainless Steel Fasteners are highly regarded for their exceptional corrosion resistance and durability, particularly in harsh environments. These fasteners are an excellent choice for applications involving aggressive chemical processes, such as those in chemical plants, petrochemical industries, and marine environments. Manufactured according to ASTM A193, ASME SA193, and DIN 1.4539 standards, these fasteners provide superior resistance to acids, chlorides, and sulfuric compounds, ensuring long-lasting performance and reliability.
As a leading stainless steel 904L fasteners manufacturer, Vision Alloys produces these fasteners using high-quality materials and advanced manufacturing techniques. The alloy's composition includes 19-23% chromium, 23-28% nickel, 4-5% molybdenum, 1-2% copper, and low carbon content. This blend enhances the fasteners' resistance to pitting and crevice corrosion while maintaining excellent mechanical properties. Adding copper improves resistance to sulfuric acid, making SS 904L fasteners ideal for chemical handling and processing equipment.
Our role as a stainless steel 904L fasteners supplier in India involves providing top-quality products and offering comprehensive support to our clients. We supply a wide range of fasteners, including bolts, nuts, washers, and screws, available in various sizes and specifications to meet diverse industrial requirements. Each product undergoes rigorous quality control processes to meet international standards and delivers reliable performance in critical applications. Our technical expertise and industry knowledge enable us to assist customers in selecting the most suitable fasteners for their specific needs, ensuring optimal safety and efficiency.
The stainless steel 904L fasteners price varies depending on the size, type, and quantity of the fasteners required. Generally, the cost ranges from 1500 to 1800 per unit, reflecting the material's high quality and specialized nature. Despite the higher cost compared to standard stainless steel, the investment in 904L fasteners pays off in applications where corrosion resistance and longevity are crucial. Our commitment to providing value means we offer competitive pricing without compromising on the quality and performance of our products.
