Description

At Siddhi Metal Industries, we offer a comprehensive range of Stainless Steel Flanges & Fittings, crafted to meet the highest industry standards. Our products are widely used across sectors including food processing, petrochemicals, pharmaceuticals, and power plants, owing to their exceptional corrosion resistance and mechanical strength.

🔧 Product Overview

• Alloy 304 Weld Neck Flanges are a preferred choice for manufacturing drawn stainless parts such as sinks, hollow-ware, and saucepans due to their excellent durability.
• Grade 304L Lap Joint Flanges excel in severely corrosive environments, requiring weld annealing only when subjected to excessive stress loads.
• 304L Orifice Flanges are versatile and used in both home and commercial applications.
• 304L Stainless Steel Flanges find widespread use in food processing, especially in beer brewing, milk processing, and wine making.
• AISI 304H Slip-On Flanges are common in heat exchangers, boilers, and petroleum refineries.
• SS 304H Blind & Spectacle Flanges offer higher tensile yield strength and superior creep strength, suitable for elevated temperature applications.

The carbon content of SS 304H weld neck flanges is controlled between 0.04% to 0.10% to enhance strength at temperatures exceeding 800°F (427°C).
