What is Q370qC bridge steel plate

1. Q370qC belongs to bridge steel, Q - the first letter of the Chinese pinyin of the word "yield" for the yield point of bridge steel; 370 - the value of the yield point, in Mpa; q - the first letter of the Chinese pinyin of the word "bridge" for bridge steel; C - The quality level is C level. Q370qC bridge steel plate is used to make road bridges and railway bridges (including cross-sea bridges) with riveted and bolt-welded structures. Q370qC executive standard: GB/T714.

2. Chemical composition of Q370qC bridge steel plate:
C: ≤0.18; Si: ≤0.55; Mn: 0.90 - 1.70; P: ≤0.025; S: ≤0.020; Nb: ≤0.06; V: ≤0.08; Ti: ≤0.03; Cr: ≤0.80; Ni: ≤0.50; Cu: ≤0.55; N: ≤0.012; Mo: ≤0.20; Als: ≥0.015.

3. Tensile yield strength of Q370qC bridge plate:
Yield: ≤50mm: ≥345MPa, 50-100mm: ≥335MPa

4. Q370qC, Q370qD, Q370qE steel plate delivery status: hot rolling, controlled rolling, normalizing/normalizing rolling, thermomechanical rolling TMCP state delivery.

5. Z-direction performance of Q370qC bridge steel plate:
Q370q steel plate is routinely used in bridge manufacturing and building structure construction. If you need Z-direction performance in the thickness direction, you can choose Z15/Z25/Z35 grades with Z-direction. Namely Q370qC-Z15, Q370qC-Z25, Q370qC-Z35, Q370qD-Z15, Q370qD-Z25, Q370qD-Z35, Q370qE-Z15, Q370qE-Z25, Q370qE-Z35.
