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 90°/45°Elbow Introduction
An Forged Socket weld elbow is installed between two lengths of pipe (or tubing) to permit a change of direction, typically a 90° or 45° angle The ends may be machined for butt welding, threaded (usually female), or socket. When the ends differ in size, it’s referred to as a reducing (or reducer) elbow.
A Forged 90º Socket weld elbow, also referred to as a “90 bend”, “90 ell” or “quarter bend”, attaches readily to plastic, copper,cast iron, steel, and lead, and is connected to rubber with stainless-steel clamps. Other available materials include silicone, rubber compounds, galvanized steel, and nylon. It’s primarily accustomed connect hoses to valves, water pumps and deck drains. A Forged 45º Socket weld elbow, additionally referred to as a “45 bend” or “45 ell”, is usually employed in water-supply facilities,food, chemical and electronic industrial pipeline networks, air-conditioning pipelines, agriculture and garden production, and solar-energy facility piping.

Alloy 20 Forging Technology Socket Welding 90°/45°Elbow Processing
1.Raw Material Inspection and Preparation:
4.Hot Forging Forming:
Adopt qualified carbon steel, stainless steel and alloy steel bar/pipe blanks complying with ASTM and ASME standards. Inspect chemical composition, mechanical properties and surface condition to eliminate raw material defects.
2.Precision Blanking:
2.Precision Blanking:
Cut raw materials into fixed-size blanks according to elbow specifications.Ensure neat cutting surface, uniform size and stable blank weight for consistent forging quality.
3.High-Temperature Heating:
3.High-Temperature Heating:
Heat steel blanks to standard forging temperature in industrial furnaces. Precisely control heating parameters to avoid overheating or underheating and ensure qualified metal fluidity for forming.
4.Hot Forging Forming:
Apply precision die forging technology. Integrally form heated blanks with dedicated 90° and 45° elbow molds to ensure smooth arc, uniform wall thickness and dense internal structure.
5.Trimming and Shaping:
Remove forging flashes and excess materials, and correct minor deformation. Ensure standard bending radius, flat end face and regular overall dimension of elbows.
6.Heat Treatment:
Perform normalization and quenching & tempering for carbon steel elbows, and solution treatment for stainless steel elbows. Eliminate forging stress and improve mechanical performance and corrosion resistance.
7.Precision Machining:
Machine both ends to form standard socket welding holes and grooves. Strictly control aperture tolerance, groove depth and flatness to meet socket welding assembly requirements.
8.Surface Finishing:
Remove internal and external burrs, oxide scales, rust and oil stains. Polish surfaces to achieve smooth and defect-free appearance.
9.Dimensional Inspection:
Accurately detect elbow angle, caliber, wall thickness, bending radius and socket size. All dimensions conform to ASME B16.11 and GB/T 14383 tolerance standards.
10.Non-Destructive Testing:
Conduct ultrasonic and penetrant NDT to detect cracks, inclusions and other internal and surface defects, ensuring 100% qualified forging quality.
11.Marking and Warehousing:
Mark specifications, material grade, execution standard and heat number on qualified products.Complete anti-rust treatment and classified packaging before warehousing.
