Super Lowest Price 20# Thick Wall Seamless Pipe - Warranty sales of 4140 alloy steel pipe manufacturer – Weichuan Detail:
16Mn is a low-alloy high-strength structural steel: the carbon content is 0.1% – 0.25%, and the main alloy elements manganese, silicon, vanadium, niobium and titanium are added; Its total alloy content is less than 3%. According to the strength, it is divided into four levels: 300, 350, 400 and 450MPa. There are mainly q295, Q345, Q390, Q420 and Q460 “Q” is the Chinese Pinyin capital prefix of the word “Qu” that yields, and the subsequent number is the minimum yield point of the brand (σ s) The subsequent symbols are divided into a, B, C and d according to the content of impurity elements (sulfur and phosphorus) in the steel from high to low and with the change of carbon and manganese. Among them, Grade A and B steels are usually called 16Mn.

16Mn seamless steel pipe
16Mn seamless steel pipe
16Mn seamless steel pipe is a kind of material. Seamless steel pipe used to be called seamless steel pipe.
The current method is: Q345B seamless steel pipe. The similar materials are Q345C, Q345D and Q345E. The quality grade symbol a, B, C, d e indicates different requirements for impact test. The impact test temperature is + 20 ° 0 ° to 20 ° 40 ° respectively. 16Mn is a material of seamless steel pipe.
ABCD indicates the quality grade Q235. The quality grade is divided into four grades A, B, C and D. from a to D indicates the quality from low to high.
Requirements for different quality levels are as follows:
A – provide s, P, C, Mn, Si chemical composition and Fu, FY δ 5（ δ 10) , 1800 cold bending test can be provided according to the buyer’s needs, but there is no impact energy regulation, and the carbon content and manganese content are not taken as the delivery conditions.
B – provide s, P, C, Mn, Si chemical composition and Fu, FY δ 5（ δ 10) , cold bend 180 ‘test. It also provides impact energy AK ≥ 27j at + 200C – in addition to the requirements of class B, it also provides impact energy AK ≥ 27j at 00C.
C – in addition to the requirements of level B, the impact energy AK ≥ 27j at – 200C is also provided. E — in addition to the requirements of level B, the impact energy AK ≥ 27j at – 400C is also provided.
