Q345B/16Mn DIN17175 hot finish alloy steel seamless pipes for pressure vessels
16Mn seamless steel pipe is a relatively important material for seamless steel pipe, and it is also a relatively useful steel. Recently, especially in capital construction pipelines, houses, and railway bridges, it has given full play to a relatively huge effect. Generally, the original factory paints the color code on the outer surface of the pipe fittings. There is very little difference from the general carbon steel appearance estimation. The color of 16Mn turns black and dark.
16Mn seamless pipe is a material in steel. In the past, a name for steel. The current name is: Q345.
Main chemical elements composition of Q345B/16Mn DIN17175 hot finish alloy steel seamless pipes :

Where 16Mn seamless steel pipes and ordinary steel pipes are applicable:
1. Ground seam steel pipe for fluid: GB8163-2008
2. Seamless steel pipe for boiler: GB3087-2008
3. High pressure seamless pipe for boiler: GB5310-2008
4. High-pressure seamless steel pipes for fertilizer equipment: GB6479-1999
5. Seamless steel pipe for geological drilling: YB235-70
6. Seamless steel pipe for oil drilling: YB528-65
7. Seamless steel pipe for petroleum cracking: GB9948-88
8. Special seamless pipe for oil drill collar: YB691-70
9. Seamless steel pipe for automobile half shaft: GB3088-1999
10. Seamless steel pipe for ships: GB5312-1999
11. Cold-drawn cold-rolled precision seamless steel pipe: GB3639-1999
16Mn seamless steel pipe use:
The special steel grade for bridges is "16Mnq", the special steel grade for automobile beams is "16MnL", and the special steel grade for pressure vessels is "16MnR".
16mn seamless pipe weight calculation formula:
[(Outer diameter-Wall thickness)*Wall thickness]*0.02466=kg/m (weight per meter)
This type of steel relies on adjusting the amount of carbon (C) to improve the mechanical properties of the steel. Therefore, according to the level of carbon content, this type of steel can be divided into:
Low carbon steel-carbon content is generally less than 0.25%, such as 10, 20 steel, etc.;
Medium carbon steel-carbon content is generally between 0.25 and 0.60%, such as 35, 45 steel, etc.;
High carbon steel-carbon content is generally greater than 0.60%. This type of steel is generally not used in the manufacture of steel pipes.
Nothing is more than important and good quanlity and integrity.
