Based in Delhi, India, Harshita Stainless is a well-known producer and supplier of stainless steel 304 flanges, providing premium solutions for safe and leak-proof pipe systems. Harshita Stainless, which is renowned for its durability, corrosion resistance, and precision engineering, makes sure every flange satisfies both domestic and international standards. The company serves a variety of industries, including chemical processing, food and beverage, water treatment, and pharmaceuticals, with state-of-the-art manufacturing facilities and a customer-first philosophy. Harshita Stainless is a dependable partner for dependable piping components throughout India because it offers a large selection of 304 flanges in different sizes and pressure ratings.
The main constituents of stainless steel 304 flanges are 18–20% chromium and 8–10.5% nickel, with a maximum carbon content of 0.08%. At moderate temperatures, this austenitic stainless steel provides exceptional strength, good weldability, and resistance to corrosion. Tensile strength of roughly 515 MPa, yield strength of 205 MPa, and elongation of roughly 40% are among the mechanical characteristics. One of the most adaptable materials for flange manufacturing is stainless steel 304, which is non-magnetic when annealed and retains its performance in a variety of settings.

Harshita Stainless follows high-quality standards for its Stainless Steel 304 Flanges. Every flange is thoroughly tested for dimensional checks, visual inspections, and non-destructive testing such as ultrasonic and magnetic particle tests. In addition to that, the flanges are even submitted to mechanical testing in terms of tensile, hardness, and impact tests to confirm their strength and durability. All the products have the relevant certificates. They also carry material test reports (MTRs) and meet international standards. This will provide reliable performance in various industrial applications.
SS 304 long weld neck flanges are designed for high-stress applications, featuring a long tapered neck that provides a strong, continuous weld connection. They offer excellent strength and resistance to leakage.
SS 304 lap joint flanges are versatile components designed for ease of assembly and disassembly. They feature a loose fit, allowing for easy alignment and maintenance, with excellent resistance to corrosion.
SS 304 reducing flanges are used to connect pipes of different diameters, providing a smooth transition between sizes. They ensure a secure, leak-proof joint while offering strong corrosion resistance and durability.
Industries that need robust, hygienic, and corrosion-resistant piping connections frequently use stainless steel 304 flanges. Water treatment facilities, dairy, petrochemicals, pharmaceuticals, food and beverage processing, and general industrial piping systems are among the applications. These flanges are suitable for both hot and cold temperature environments and are frequently used in systems transporting water, gases, chemicals, or steam. Thanks to their excellent weldability and formability, they are ideal for assembling or repairing pipelines. SS 304 flanges ensure tight sealing, ease of maintenance, and long-term performance, making them essential components in high-performance and corrosion-sensitive applications.
