A514Gr.Q material is a quenched and tempered
Alloy steel plate for structural applications requiring high yield strength combined with good formability and toughness. A514Gr.Q high strength steel is suitable for engineering machinery and jack-up offshore drilling platform racks with a high strength A514Gr.Q steel plate with thickness of 5 ~ 150mm.
Standard: A514Gr.Q steel is a quenched and tempered high strength weldable steel plate under the ASTM A514 standard. ASTM A514 plate is mainly used in places that require high tensile and high yield, engineering automobile lifting gear, racks for offshore platforms.

WeldabilityWelding of A514Gr.Q plates shall be performed in accordance with the applicable welding code. In the absence of a specified welding code, the following suggested minimum preheat and interpass temperatures and welding consumables are provided. Special welding consumables and welding procedures may be required to avoid detrimental effects on the mechanical properties of the base metal. Low hydrogen practices are strongly recommended, including the removal of surface moisture.
