Product Description
Alloy 20 Introduction
Alloy 20 is an austenitic stainless steel containing less than 50% iron and is used in applications involving sulfuric acid. Its
corrosion resistance also finds other applications in the chemical, petrochemical, power generation, and plastics industries.Alloy 20 exhibits superior resistance to pitting and chloride ion corrosion compared to 304 stainless steel and is comparable to316L stainless steel. Its copper content protects it from sulfuric acid. Alloy 20 is typically selected to address the potentialstress corrosion cracking issues of 316L stainless steel.

Alloy 20 Forging Flange Socket Welding Flanges Introduction
Socket Welding Flange is a reliable forged pipe connection fitting designed for socket welding pipeline assembly. Different from threaded flanges, it adopts a socket groove structure to allow pipe insertion, followed by fillet welding at the socket opening to achieve firm connection and excellent tightness. This design avoids through-weld defects, simplifies installation operation, and improves welding efficiency, making it highly suitable for small-diameter, high-pressure piping systems. Manufactured from premium carbon steel, stainless steel and alloy steel compliant with ASME B16.5 and ASTM standards, socket welding flanges feature high structural strength, precise dimensional accuracy and superior fatigue resistance. They are widely used in petroleum, chemical, natural gas, power and industrial equipment piping, especially ideal for high-temperature, high-pressure and vibration-prone working environments where stable and leak-free connection is required.

Alloy 20 Forging Flange Socket Welding Flanges Product Processing
1.Raw Material Inspection & Blanking:
Adopt high-quality carbon steel, stainless steel and alloy steel round bars that comply with ASTM and ASME standard specifications. Strictly inspect chemical composition, mechanical properties and surface integrity to rule out cracks, inclusions and other defects. Qualified raw materials are precisely cut into fixed-length blanks for standardized flange forging production.
2.Heating & Closed Die Forging:
2.Heating & Closed Die Forging:
Heat the qualified blanks evenly to the specified forging temperature with accurate parameter control. Adopt closed-die integral forging to form the flange disc, sealing surface and complete socket groove structure. The forged blank owns dense internal grain structure, uniform wall thickness and stable mechanical performance, meeting high-pressure pipeline connection requirements.
3.Trimming, Straightening & Heat Treatment:
3.Trimming, Straightening & Heat Treatment:
Remove forging flashes and redundant edges, and correct minor forming deformation to ensure regular flange shape and flat surface. Conduct professional heat treatment including stress relief annealing,normalizing and solution treatment according to different materials, eliminating residual forging stress and improving overall structural stability and corrosion resistance.
4.Precision Machining & Socket Processing:
4.Precision Machining & Socket Processing:
Perform precision turning on flange end face, sealing surface and outer circle. Precisely machine the inner socket groove and inner hole size in strict accordance with ASME B16.5 standards, ensuring accurate dimensional tolerance and smooth pipe insertion, which guarantees stable fillet welding assembly effect.
5.Surface Finishing & Quality Testing:
Thoroughly clean internal and external burrs, oxide scales and machining residues. Carry out full dimensional inspection, visual inspection and nondestructive testing to ensure zero structural defects, and all technical indicators meet industrial high-pressure piping standards.
6.Marking, Anti-rust Treatment & Warehousing:
6.Marking, Anti-rust Treatment & Warehousing:
Mark qualified socket welding flanges with material grade, specifications, pressure class, execution standard and heat number. Complete professional anti-rust protection and standardized packaging before classified warehousing and delivery.
