GB/T 8162 20CrMo refers to the seamless steel pipe produced in accordance with the Chinese national standard GB/T 8162 and made of 20CrMo steel. This seamless steel pipe is made of 20CrMo, a low-alloy high-strength steel, which has excellent mechanical properties and technological properties.

The main chemical composition of 20CrMo seamless steel pipe includes carbon (C), silicon (Si), manganese (Mn), chromium (Cr) and molybdenum (Mo). The specific chemical composition range is: C content in 0.17% ~ 0.24%, Si content in 0.17% ~ 0.37%, Mn content in 0.40% ~ 0.70%, Cr content in 0.80% ~ 1.10%, Mo content in 0.15% ~ 0.25%. The precise proportion of these elements makes the steel pipe have excellent strength and toughness.

 

GB/T 8162 20CrMo Features:

 

High strength and wear resistance: 20CrMo seamless steel pipe has high strength and good wear resistance, and can withstand greater pressure and friction.

 

Good hardenability and weldability: The steel pipe has high hardenability, good weldability, and is not prone to cold cracking.

 

Excellent machining performance: 20CrMo seamless steel pipe has good machinability and cold strain plasticity, and is easy to carry out various processing operations.

 

The delivery status of GB/T 8162 20CrMo seamless steel pipe is generally determined according to the negotiation between the supply and demand parties, and indicated in the contract. Common delivery conditions include hot rolling, hot expanding, cold drawing, or normalizing and tempering conditions. In addition, the surface of the steel pipe can be polished, pickled or polished according to the requirements.

 

20CrMo seamless steel pipe is widely used in many fields because of its excellent mechanical properties and processing properties. It is often used to manufacture high-pressure tubes and various fasteners that work in non-corrosive media and in media with a working temperature below 250℃ and a mixture of nitrogen and hydrogen. In addition, it is also used to manufacture more advanced carburized parts, such as gears, shafts, etc. At the same time, due to its high strength and good wear resistance, it is also suitable for the manufacturing of key components in petroleum, chemical, electric power, machinery and other industries.

 

In summary, GB/T 8162 20CrMo seamless steel pipe ,with its unique chemical composition and excellent performance characteristics, has a wide range of application prospects in many industrial fields.
