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 Technology Threaded Union Introduction
1.Core Definition
The pipe connection is achieved by screwing the internal thread of the pipe onto the threaded joint (or screwing the external thread of the joint onto the pipe), utilizing the mechanical interlocking force of the threads to connect the pipeline, without the need for welding and allowing for quick disassembly. 2.Core feature Ease of use:
Installation and disassembly only require a wrench, resulting in high construction efficiency. It is suitable for pipelines
that need frequent maintenance (such as building fire branch pipes, factory compressed air branch lines). Pressure limit:
Generally applicable to medium and low pressure scenarios with a maximum of 1500LB. Long-term vibration may cause thread loosening and leakage. Sealing assistance: Dependent on auxiliary sealing materials such as tape and sealant, the sealing reliability is weaker than socket welding.

Alloy 20 Forging Technology Threaded Union Product Processing
Choose appropriate materials, such as steel, stainless steel, and aluminum alloy, based on specific requirements. Select the hardness, corrosion resistance, and other properties of the materials.
2.Blank forming:
The pipe fittings are mainly formed by pressing and forging round steel or steel ingots into blanks.
3.Machining:
4.Post-processing techniques:
5.Quality review:
6.Assembly and inspection:
3.Machining:
The blanks are machined using a lathe, including designing the parameters of the threaded joints, selecting appropriate machining tools and materials, and performing pre-processing (coarse and fine machining) steps. During the coarse machining stage, a thread milling machine or thread broaching machine is used for initial processing; in the fine machining stage,a precision lathe is used for meticulous processing to ensure the accuracy and surface quality of the joints.
4.Post-processing techniques:
After processing, post-processing techniques such as deburring, grinding, and surface treatment are carried out to improve the durability and appearance of the joints.
5.Quality review:
Measure and inspect the dimensions, shapes, and surface quality of the threads to ensure that the joints meet the design requirements.
6.Assembly and inspection:
Perform the assembly and inspection of the threaded joints through a strict assembly and inspection process to ensure that each joint meets the high-quality and high-performance standards.
