I. 16mn seamless steel pipe standard
16Mn is a low-alloy high-strength structural steel: the carbon content is 0. 1%-0.25%, and main alloying elements such as manganese, silicon, vanadium, niobium and titanium are added; Its total alloy content
16Mn is a kind of seamless steel pipe material.
ABCD stands for quality grade? Q235 quality grade is divided into four levels: A, B, C and D, with A to D indicating the quality from low to high. The requirements of different quality grades are as follows: A—— Provide the chemical composition of S, P, C, Mn, Si and fu, fy and δ5(δ 10), and provide 1800 cold bending test according to the buyer's requirements, but there is no impact work requirement, and carbon content and manganese content are not the delivery conditions.
B—— Provide the chemical composition of S, P, C, Mn and Si, and the tests of fu, fy, δ5(δ 10) and cold bending 180'. It can also provide impact work Ak≥27J at+200 C.
C—— In addition to the requirements of Grade B, it also provides the impact energy Ak≥27J at 00C. ?
D- In addition to the requirements of Grade B, it also provides impact energy Ak≥27J at -200C? E—— In addition to the requirements of Grade B, the impact energy AK at -400℃ shall be provided ≥ 27J. ..
16MN as the material and the national standard as the production standard. There is no necessary connection between them.
16MN can be used as structural pipe, so the production standard of the structure is GB8 162.
If it is a fluid pipeline, the production standard is GB8 163.
The production standard is related to the use.
