ASTM A514 (T1) Plate -- High Strength Steel

---

ASTM A514 is most commonly used as structural steel in cranes and large heavy-load machines.   

Other names for ASTM A-514 are T-1 (ArcelorMittal name), Algoma 100 (Algoma Steel). 

A514 steel plate is a steel plate material known for its high yield strength, weldability, and toughness, even at low temperatures. A514 is a low carbon quenched and tempered alloy steel that is a low-cost, high performing material for structural use and high wear machine applications. This steel plate has a yield strength of 100,000 psi (100 ksi or approximately 700 MPa).  

 Available in eight grades: B, S, H, Q, E, F, A and P 

 The A514 plate steels are a group of quenched and tempered alloys with many attractive advantages and characteristics. It has a minimum tensile strength of 100 ksi (689 MPa) and at least 110 ksi (758 MPa) ultimate. Plates from 2.5 inches to 6.0 inches have a specified tensile strength of 90 ksi (621 MPa) and 100 - 130 ksi (689 - 896 MPa) ultimate. A514 plate also provides good weldability, and toughness at low atmospheric temperatures. The ASTM A514 group is designed for a wide range of structural uses as well as machinery and equipment.  However, the primary use is as a structural steel in building construction. This group of steel, which also includes A517 and alloy steel combine optimum strength, toughness, corrosion resistance, impact-abrasion resistance, and long-term economy.
