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 potential stress corrosion cracking issues of 316L stainless steel.

Alloy 20 Butt Welding Reducer Introduction
Alloy 20 (UNS N08020) butt-weld reducer is a high-performance nickel-iron-chromium alloy pipe fitting used to connect steel pipes of different diameters in industrial piping systems. It is mainly divided into concentric reducer and eccentric reducer.Alloy 20 material contains reasonable content of nickel, chromium, copper and molybdenum. It provides excellent resistance to sulfuric acid, phosphoric acid, pitting corrosion and stress corrosion cracking, performing much better than ordinary stainless steel in harsh chemical environments.This product is manufactured in accordance with international mainstream standards including ASME B16.9 and ASTM B366. It supports various specifications such as SCH5S, SCH10S, SCH40, SCH80 and customized sizes.Compared with ordinary carbon steel and stainless steel reducers, Alloy 20 butt-weld reducers feature uniform wall thickness,smooth inner wall, stable mechanical properties and excellent weldability. No post-weld heat treatment is required during construction.Widely used in chemical engineering, petrochemical, pharmaceutical, fertilizer, environmental protection wastewater treatment and other corrosive medium pipeline projects.

Product processing
Alloy 20 Butt Welding Reducer processing
1.Raw Material Inspection
elect original Alloy 20 seamless pipes and steel plates. Strictly test chemical composition, mechanical properties and surface quality to ensure all raw materials fully meet ASTM and ASME standard requirements.
2.Precision Cutting & Blanking
According to customer size and wall thickness parameters, perform computer precision sizing and cutting. Remove burrs to ensure neat incision and consistent tube blank size.
3.Hot Forming/Hydraulic Bulging
Adopt integral hot pressing or hydraulic bulging technology. Through metal axial and radial compensation, the tube blank is integrally formed into concentric or eccentric reducer to ensure uniform wall thickness and smooth inner cavity.
4.Solution Heat Treatment
Perform professional solution annealing treatment to eliminate internal processing residual stress, stabilize alloy
microstructure, and maximize the original corrosion resistance and mechanical toughness of Alloy 20 material.
microstructure, and maximize the original corrosion resistance and mechanical toughness of Alloy 20 material.
5.CNC Precision Machining & Beveling
Use CNC lathes for finish machining of product overall dimensions and welding bevels. The bevel angle and tolerance strictly comply with piping welding standards to ensure tight butt welding on site.
6.Surface Treatment
Conduct surface polishing, pickling and passivation treatment to remove oxide scales, welding traces and impurities. A dense protective passivation film is formed on the surface to improve finish and anti-corrosion performance.
7.Strict Finished Product Testing
Carry out full-item inspection, including dimensional tolerance detection, appearance inspection, hardness test and NDT
non-destructive testing. Unqualified products are reworked or scrapped; only qualified products enter the packaging process.
non-destructive testing. Unqualified products are reworked or scrapped; only qualified products enter the packaging process.
8.Standard Packaging & Delivery
Adopt professional anti-collision and moisture-proof packaging. Mark product specifications, execution standards, batch numbers and other information clearly to ensure intact and standardized delivery.
