Metalloy International is the most respected manufacturer and distributor of SS 304 flanges used by industries worldwide. Mastered with all the requisite skills from many past generations and serving different industries. We manufacture SS 304 flanges in the standard and customized format requested by customers.

Mechanical Properties

  1. Strength:  stainless steel  S30400 offer excellent tensile strength, withstanding high pressures and temperatures. Their unique composition makes them durable enough for robust applications, offering a yield strength of around 205 MPa.
  2. Hardness: The Brinell hardness of Stainless Steel 304 Flanges ranges from 123 to 147, providing an optimal blend of stiffness and flexibility.
  3. Elongation: These flanges offer an elongation at around 40-45% break, allowing them to deform without breaking under tensile stress.

Chemical Properties

  1. Corrosion Resistancestainless steel 1.4301 flanges are admired for their corrosion resistance. The chromium content helps form a passive film of chromium oxide on the surface, protecting against corrosion in various environments.
  2. Oxidation Resistance: Capable of withstanding temperatures up to 870°C, SS 304 shows excellent oxidation resistance. This ensures longevity, especially in environments where oxidative agents are present.

Physical Properties

  1. DensityASME SA182 stainless steel f304 flanges have a density of approximately 8.0 g/cm³, balancing weight and durability.
  2. Thermal Conductivity: With a thermal conductivity of 16.2 W/m·K at 100°C, these flanges efficiently conduct heat, making them suitable for temperature control applications.
  3. Thermal Expansion: The coefficient of thermal expansion for stainless steel 304 is 17.2 x 10^-6 /°C, reflecting moderate expansion when subjected to changes in temperature.

 

We maintain the uniform quality and ensure that precise flanges are given or in a customizable format as requested by the customer who meets the requirement. These flanges have many advantageous features, such as very low maintenance costs, resistive properties, structure, and high strength. Due to its different characteristics, and attributes our customers appreciate ASTM A182 SS 304 Flanges developed at Metalloy International. These flanges, along with oxidation, pitting and corrosion resistance, give endurance, high tensile strength and toughness. In construction and dimensional precision, it also has sturdiness.

At Metalloy International, we produce and supply stainless steel 304 flanges of the highest quality. By delivering the latest and highest quality goods, we believe in establishing and sustaining professional relationships with clients. We have an exclusive selection of these flanges that are tested to ensure error-free performance under superior inspection. To supervise ductility and consistency, our quality management team conducts numerous tests. In order to verify characteristics like hardness, mineral content, rigid structure, and several other, our products undergo numerous destructive and non-destructive tests. We have stored a large quantity of SS 304 flanges that can be distributed to our customers immediately during an urgent situation.

Metalloy International is a well-established company with an excellent manufacturing unit. We always ensure that all the needs of our valuable customers are met by our goods. To produce these stainless steel 304 raised flanges, our seasoned and highly trained manufacturing team includes skilled staff, software professionals and field experts working together. During the production process, cutting-edge machinery and innovative methodology are used. It is available on the market at very competitive rates for our clients. To prevent any harm during transit, the traditional form of packaging is used. Upon their request, we also provide personalized packaging to our clients.
