Seamless Steel Pipes 20# 45# From China Factory
High - Quality Seamless Steel Pipes 20# and 45# from China Factory: Your Reliable Choice
Our China - based factory specializes in the production of seamless steel pipes, with 20# and 45# steel grades being among our star products. These pipes are manufactured with precision and adhere to strict quality standards, making them suitable for a wide range of applications.
1. Material Grades: 20# and 45# Steel
1.1 20# Steel Seamless Pipes
The 20# steel is a low - carbon steel with a carbon content of approximately 0.17 - 0.24%. This low carbon content endows the steel with good plasticity and weldability. The seamless pipes made from 20# steel are highly malleable, which means they can be easily formed into various shapes without the risk of cracking. This property makes them ideal for applications that require extensive bending, flanging, or other forming operations, such as in the manufacturing of automotive parts like hydraulic cylinders and in the construction of plumbing systems.
In addition to its formability, 20# steel seamless pipes also offer decent mechanical properties. They have a relatively low strength compared to higher - carbon steels but still provide sufficient tensile strength and yield strength for general - purpose applications. The pipes are also resistant to mild corrosion, which makes them suitable for use in environments where the corrosive conditions are not overly harsh.
1.2 45# Steel Seamless Pipes
The 45# steel, on the other hand, is a medium - carbon steel with a carbon content of around 0.42 - 0.50%. The higher carbon content gives 45# steel greater strength and hardness compared to 20# steel. Seamless pipes made from 45# steel are known for their excellent mechanical properties, such as high tensile strength, which can reach up to 600 MPa. This makes them suitable for applications that require high - load - bearing capacity, like in machinery manufacturing, where they can be used for shafts, axles, and gears.
