What is the Q355NE-Z35 steel?
Standard: GB/T1591-2018
Grade: Q355NE-Z35
Category: low-alloy high-strength structural steel
The new performance specification specifies the Q355 quality levels are B, C, D, E, F (no A level). Q--indicating yield strength, and N-indicates that the heat treatment is normalizing or normalizing rolling.
Q355NE-Z35E steel plate special technical conditions, such as Z-direction, flaw detection, carbon equivalent and other mechanical properties.
Chemical composition of Q355NE-Z35 low alloy high strength structural steelC: ≤0.18
Si: ≤0.50
Mn: 0.9-1.65
P: ≤0.025
S: ≤0.02
V:0.01-0.012
Ti: 0.006-0.05
Cr: ≤0.3
Ni: ≤0.5
Mo: ≤0.1
Q355NE steel is a low-alloy high-strength steel plate, so the original performance specification for low-alloy high-strength structural steel is GB/T1591-2008 changed to GB/T1591-2018 from February 1, 2019, and the original
Q345B steel changed to Q355B steel.
