Material selection of thick walled conical steel pipe
Jan 19,2026
Carbon steel: mainly made of 20 # steel, it has good plasticity, toughness, and weldability. Its toughness is better after hot rolling or normalizing, and it is a commonly used material for conical steel pipes.
Stainless steel, such as 304, 316L, etc., has strong corrosion resistance but high manufacturing costs, making it suitable for scenarios that require high corrosion resistance.
Alloy steel: such as Q345B, 12Cr5Mo, etc., improve strength, heat resistance or corrosion resistance through alloy elements to meet special working conditions.
Special materials: such as titanium alloy, used in fields that require extremely high weight and corrosion resistance.
