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 Fitting Socket Welding Olet Introduction
Socket Welding Olet is a high-pressure forged reinforcing branch pipe fitting designed for branch connection on industrial main pipelines. It consists of an integrated saddle base, reinforced body and socket welding outlet. The integral reinforcing structure effectively strengthens the pipe branch position, avoiding local stress concentration and ensuring stable and safe performance under high-temperature, high-pressure and harsh working conditions. Different from threaded olet, it adopts socket welding connection on the branch end, providing higher connection strength and better tightness. Manufactured from premium carbon steel,stainless steel and alloy steel compliant with ASTM A182 standards, socket welding olets feature compact structure, reliable pressure resistance and excellent welding performance. They are widely used in petroleum, natural gas, chemical, power, nuclear energy and aerospace industries for safe and durable branch take-off of pressure vessels and process piping systems.

Alloy 20 Forging Fitting Socket Welding Olet Product Processing
1.Raw Material Inspection & Blanking:
Qualified bar blanks of carbon steel, stainless steel and alloy steel conforming to ASTM A182 standards are selected. Chemical composition, mechanical properties and surface condition are inspected to exclude internal and surface defects. Raw bars are cut into fixed‑length workpieces with neat end faces for forging.
2.Heating & Closed‑Die Forging Forming:
Blanks are heated to the specified forging temperature under precise temperature control. Hot closed‑die forging is adopted to integrally shape the saddle profile, reinforced body and socket‑weld outlet,ensuring compact metal structure and sufficient wall thickness on the reinforcement zone.
3.Trimming, Straightening & Heat Treatment:
Forging flashes and surplus material are removed, followed by straightening to correct forming deformation. Targeted heat‑treatment is implemented: stress‑relief annealing for carbon‑steel parts and solution treatment for stainless‑steel products, eliminating forging‑induced internal stress and improving mechanical strength and corrosion resistance.
4.Precision Machining & Socket Processing:
The saddle surface is machined to match the outer curvature of the main pipe.The branch bore and socket‑weld cavity are precisely turned to meet dimensional tolerance requirements for socket‑weld connection.
5.Surface Finishing & Quality Inspection:
Burrs and oxide scales are cleaned from inner and outer surfaces. Full dimensional check, visual inspection and nondestructive testing are performed to verify reinforcement dimensions, socket depth and all technical parameters.
6.Marking, Anti‑rust Treatment & Packaging:
Qualified socket‑welding olets are marked with material grade, size, applicable standard and heat number. Anti‑rust protection and standard packaging are completed prior to warehousing and shipment.
