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 Technology Socket Welding Tee Introduction
A Socket Weld Tee, also known as a socket weld tee fitting, is a high-pressure pipe connection component manufactured using round steel or steel ingots through die-forging and machining on a lathe. It is used in piping systems to achieve a
“one-pipe-to-two-branches” configuration. Its core structure includes three ports: one main pipe port and two branch pipe ports,all of which utilize socket weld connections. Unlike ordinary threaded tees or butt-welded tees, the ports of a Socket Weld Tee are designed in a “socket” form, allowing pipes to be directly inserted into the sockets and then secured via welding to form a tight, sealed connection. It is primarily used in high-pressure precision fields such as petrochemicals, power generation,aerospace, and defense industries. Its manufacturing processes include hot pressing, radial compression, and branch pipe stretching, differing from the metal compensation method used in hydraulic forming processes.

Forged Socket Weld Fittings Tees are categorized into two types based on structure: equal tee and reducing tee. Sizes range from DN6 to DN100, with common sizes being DN15 to DN50. Materials include carbon steel, stainless steel, and alloy steel. Pressure ratings include 3000LB, 6000LB, and SCH80. The product complies with the American Standard ASME B16.11.

Alloy 20 Forging Technology Socket Welding Tee Product Processing
1.Material Selection:
Forging-grade billets meeting ASTM composition limits are heated to 2150°F.
2.Hot Forging:
Using closed-die presses at controlled temperatures, the tee shape is formed through plastic deformation under >20,000 psi pressure – optimizing grain flow and fatigue resistance.
3.SolutionAnnealing:
Austenitic steels/alloys undergo rapid quenching to dissolve carbides and restore corrosion resistance. Post-anneal
hardness must maintain ASTM max limits.
hardness must maintain ASTM max limits.
4.Machining:
CNC lathes precisely bore sockets, ensuring exact tolerances (±0.005") and surface finishes (Ra ≤ 3.2 μm) necessary for pipe fit-up.
5.Surface Treatment:
Pickling/passivation (ASTM A380) removes iron contamination while oxidizing chromium to enhance the corrosion barrier in stainless grades.
6.Final QC:
Hydrostatic testing to 1.5x rated pressure, dimensional validation, NDE for defects.
