ASTM A514 gr P steel yield strength is high, which is one of the most obvious characteristics and one of the most important reasons why ASTM A514 gr P steel is widely used in cranes and large heavy-load machines. ASTM A514 gr P steel also has good weldability and toughness, even at low temperatures.
ASTM A514 gr P steel data sheet - A514 gr P steel chemical composition:
| C | Mn | P | S | Si | Ni | Cr | Mo | V | B |
| 0.12-0.21 | 0.45-0.70 | ≤0.035 | ≤0.04 | 0.20-0.35 | 1.2-1.5 | 0.85-1.20 | 0.44-0.60 | 0.03-0.08 | 0.001-0.005 |
ASTM A514 gr P steel yield strength and data sheet - A514 gr P steel plate mechanical properties:
| ASTM A514 | Thickness | Yield | Tensile | Elongation |
| A514 gr P | mm | Min Mpa | Mpa | Min. % |
| 20 | 690 | 760-895 | 18 | |
| 20-65 | 690 | 760-895 | 18 | |
| 65-150 | 620 | 690-895 | 18 |
ASTM A514 gr P steel yield strength reduces with the A514 gr P steel plate thickness increase. ASTM A514 gr P steel is mainly for structural use and high wear machine applications. It is designed for a wide range of structural uses as well as machinery and equipment. However, in the actual practice, the primary use of ASTM A514 gr P steel is as structural steel in building construction.
