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 to 316L 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 Fitting Swaged Nipple Introduction
Swaged nipple is a type of forged reducing pipe fitting, designed to connect pipelines of different diameters and realize smooth diameter transition within a short‑length section.It falls into two primary categories: Concentric Swaged Nipple and Eccentric Swaged Nipple.
1.The concentric type features identical centerlines at both large‑size and small‑size ends, suited for vertical piping systems.
2.The eccentric type has offset centerlines,which keeps one side flat and is mainly applied to horizontal pipelines to avoid air accumulation or liquid trapping.
As a high‑pressure forged component, swaged nipples are widely used in petroleum, chemical, natural gas, power plant,
fire‑protection and other industrial piping systems for diameter conversion of threaded, socket‑weld or butt‑weld connections.

Alloy 20 Forging Fitting Swaged Nipple Product processing
1.Raw Material Preparation & Inspection:
Bar or pipe blanks of carbon steel, stainless steel, alloy steel and other grades complying with ASTM and ASME standards are selected. Chemical composition, mechanical properties and surface quality are fully checked to rule out cracks, inclusions and defects, followed by precision blanking to obtain fixed‑length workpieces.
2.Heating & Hot‑Forging / Swaging Forming:
2.Heating & Hot‑Forging / Swaging Forming:
Blanks are heated to the required forging temperature under controlled heating parameters. Concentric or eccentric reducing shapes are formed by die forging or rotary swaging process to achieve the required transition taper, ensuring compact metal structure and uniform wall‑thickness distribution.
3.Trimming, Straightening & Heat Treatment:
3.Trimming, Straightening & Heat Treatment:
Forging flashes are removed and workpieces are straightened to correct forming deformation. Heat‑treatment procedures including stress‑relief annealing, normalizing or solution treatment are carried out according to material requirements to eliminate internal stress and improve mechanical and anti‑corrosion performance.
4.Precision Machining:
4.Precision Machining:
Both large‑end and small‑end faces are turned, chamfered and machined to accurate dimensions. Threads or socket‑weld profiles are processed as specified to meet connection requirements.
5.Surface Treatment & Quality Testing:
5.Surface Treatment & Quality Testing:
Burrs, oxide scales and surface impurities are cleaned away; polishing, galvanizing or other surface finishes can be provided upon request. Full dimensional inspection, visual examination and nondestructive testing are performed to verify that concentric / eccentric offset tolerance and all technical indicators meet standards.
6.Marking, Packaging & Warehousing:
6.Marking, Packaging & Warehousing:
Qualified swaged nipples are permanently marked with material grade, size, standard and heat number. Anti‑rust protection and standard packaging are completed before storage and shipment.
