16Mn precision seamless steel pipe is a high-precision steel pipe processed by cold drawing or hot rolling. Since there is no oxide layer on the inner and outer walls of precision seamless steel pipes, precision seamless steel pipes have the characteristics of withstanding high pressure without leakage, high precision, high smoothness, no deformation in cold bending, no cracks in flaring and flattening, etc., so they are mainly used in production. Pneumatic or hydraulic components.
16Mn cold drawn steel pipe cutting and retail, 16Mn steel pipe wire processing, 16Mn steel pipe is a commonly used steel pipe for boilers and pressure vessels, hot rolled or normalized. It is a low alloy steel with low Mn content. The performance is similar to 20G (412-540), the tensile strength is slightly stronger (450-655), and the elongation is 19-21%, which is worse than 20G which is more than 24%. The carbon content is 0.1%-0.25%, and the main alloying elements manganese, silicon, vanadium, niobium and titanium are added.
The total alloy content of 16M low temperature steel pipe is less than 3%. According to the intensity, it is divided into 4 levels: 300, 350, 400 and 450MPa.
Chemical composition of Q345B/16Mn seamless steel pipe:
| C | Si | Mn | P | S | Ni | Cr | Cu | V | Nb |
| 0.12-0.20 | 0.20-0.60 | 1.00-1.60 | ≤0.040 | ≤0.040 | ≤0.30 | ≤0.30 | ≤0.20 | 0.02-0.15 | 0.015-0.06 |
Tensile strength: 470~660 n/m2;
Yield strength: 275~345 n/m2;
Elongation: 21%.

There are two main testing methods for 16Mn seamless steel pipes
One is the static test method, where the test force is applied slowly and without impact. The measurement of hardness is mainly determined based on the depth of the indentation, the projected area of the indentation or the size of the indentation area.
Another testing method is the dynamic testing method, where the application of test force is dynamic and impactful. This includes Shore and Leeb hardness testing methods.
The main business scope of gnee company includes alloy pipes, high-pressure boiler pipes, fertilizer special pipes, petroleum pipes, etc.
Cracking pipes, stainless steel pipes, pilot ship pipes, structural pipes, fluid pipes, line pipes, precision pipes, etc.
