Offer Ability:5 000MT/Per Month ASTM A514 Grade Q/ A514 Gr.Q alloy steel plate
ASTM A514 Grade Q/ A514 Gr.Q alloy steel plate is high strength weldable steel plate for quenching and tempering under the ASTM A514 / A514M standard. The main purpose is to use under high tensile, high yield sites. The engineering car lifting gear and the rack used in the offshore platform generally use ASTM A514 Grade Q/ A514 Gr.Q alloy steel plate.
ASTM A514 Grade Q alloy steel plate chemical composition:
| Grade | C | Mn | P | S | Si | Ni | Cr | Mo | V | Ti | Zr | Cu | B |
| A514 Gr.Q | 0.14-0.21 | 0.95-1.30 | ≤0.035 | ≤0.04 | 0.15-0.35 | 1.20-1.50 | 1.00-1.50 | 0.40-0.60 | 0.03-0.08 | ~ | ~ | ~ | ~ |
ASTM A514 Gr.Q alloy steel plate mechnical properties:
