Casting is a go-to technique for affordably manufacturing accurate and complex components. For stainless steel flanges, the process begins with melting the raw materials in an industrial furnace. The mould gets pre-heated.
A centrifuge machine permits manufacturers to pour the melted steel into the preset mould. Finally, the casting undergoes cooling before it is removed from the mould. On the downside, casting can bring in defects and internal structural errors. An SS forged flange is generally superior in mechanical and chemical properties.
We are a professional supplier of SS flange in Mumbai as per ASME B16.5
The machinability of these flanges is not brilliant, but it can get boosted by using the appropriate tools and feed rate. It also depends on the grade of stainless steel. Elements like sulfur can impact the ease of machining of SS flanges.
For example, flanges produced from ferritic grades have higher machinability than martensitic ones.
This trait also differs by heat treatment. So, highly annealed materials are trickier to machine. But a stainless steel weld neck flange produced from a precipitation-hardened grade is easier to handle after solution-treating.

SS flanges
Excellent rust resistance to water, alkalis, and some acids is a hallmark of these flanges. But a stainless steel pipe flange might erode when exposed to aggressive saline or acidic media. A protective coating like epoxy and maintenance paints can minimise corrosion.
Thorough cleaning with non-abrasive tools and non-chloride cleaners is recommended. Some sectors use a waterproof polyurethane sealant for a stainless steel lap joint flange. Passivation (eliminating ferrous contaminants) and using polymer composites are also excellent methods to prevent damage triggered by corrosion.
Here you can buy stainless steel weld neck and threaded flange in sizes ranging from 1/2β³ to 48β³ or as per customer specification

These flanges have multiple roles, like sealing a piping section or facilitating pressure testing. Clients can order a stainless steel blind flange in sizes Β½ to 24 or 48 inches (NB).
These components are available in pressure classes up to 2500 and NPS from Β½β to 24.
Clients may procure various face types for a stainless flange β it wholly depends on the application. But the raised face flange is usually favoured. A flat face flange keeps the gasket surface and the bolting circle in one plane.
Buyers may also use a tongue-and-groove stainless steel reducing flange, where the faces have a raised ring and a depression to match. The M&F flange face (male and female) comprises matching flanges. We suggest a ring-type joint flange if the application encounters higher pressures and temperatures.
High-quality manufacturing approaches integrate testing at every step, including sourcing and melting the raw material. A stainless steel threaded flange undergoes chemical analysis (spectrography) during and after production to confirm the chemical composition.
Some mills conduct mechanical and dimensional testing to ensure adherence to client specifications.
These flanges last for over 50 years when used and maintained correctly. Some mills issue Guarantee-Warranty Certificates for a stainless steel slip on flange. However, these documents relate mainly to manufacturing defects and mechanical or chemical properties and extend to around 3 to 5 years. Application-specific use will help optimise the lifespan of the flanges.
You will also receive a mill test report to certify that the product adheres to the specifications for grain size, carbon content, etc.
Manufacturers cannot provide a guarantee or warranty against defects introduced during the application, such as corrosion or wear and tear. The buyer must ensure the fitness of the stainless steel plate flanges for the application.
