What is ASTM A182 F321 material? ASTM A182 F321 / 321H stainless steel flanges are forged austenitic stainless steel grades belonging to the 321 stainless steel (SS 321) family. Titanium (Ti) stabilizes this grade to prevent intergranular corrosion, particularly in high-temperature environments. Chemical Composition of ASTM A182 F321\321H CHEMICAL LIMITS C Mn P S Si […]
SMO 254 Flanges are flange fittings made from an austenitic stainless steel alloy called SMO 254. This alloy contains higher levels of molybdenum, chromium, and nitrogen, providing exceptional resistance to corrosion, especially in highly acidic environments. SMO 254 Flanges are known for their excellent strength, impact resistance & low maintenance requirements. These flanges are widely […]

Carbon steel flanges are one of the widely used flanges in multiple industries due to their durability, strength and resistance to corrosion. They are form by heating and shaping carbon steel blocks into various shapes and sizes per the client’s requirements. Common standards include ASTM A694,ASTM A105N,ASTM A350. Accompanying pressure ratings are from class 150 […]
EN 1092-1 flange is widely used in various industries worldwide. This flange is widely used in industries such as oil, gas, mining, and commercial industries, and is now considered equivalent to ANSI flange in ANSI B16.5. EN 1092-1 flange standard is designed not only for steel flanges but also for other types of flanges. For […]
ASTM A182 is the standard specification for rolled or forged alloy, as well as stainless-steel pipe flanges, forged fittings, and parts and valves used for high-temperature service. ASTM A182 SS blind flange refers to a blind flange produced using ASTM A182 standard material. We manufacture ASTM A182 SS304L and SS316L Blind Flange, which comes in […]
Stainless steel forged flanges are disk-shaped parts most commonly used in piping. They are used in pairs and with matching flanges on valves. In pipeline engineering, flanges are mainly used for the connection of pipelines. Add sealing gasket between two flanges, and then tighten with bolt.Flanges with different pressures have different thicknesses and use different bolts. Stainless Steel […]
Carbon Steel forged flanges connectors are basically made of carbon steel. They are the primary material of carbon steel flange and end flange connectors. Common standards include ASTM A105, ASTM A350 LF2, ASTM A694, DIN 2533 and MSS SP-44. Pressure ratings from class 150 to 2500. Carbon steel forged flanges are one of the widely […]
