A514Gr.Q material is a quenched and tempered high-strength weldable steel plate under the ASTM standard. It is mainly used in places where high tensile strength and high yield are required, engineering vehicle lifting gears, and racks for offshore platforms. Depending on the thickness, its hardness is between 235-290, the yield is greater than 630MPa, and the tensile strength is greater than 700MPa.
From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
The company covers an area of 15,000 square meters and the plant construction area is 10,000 square meters. We have introduced more than 50 sets of advanced steel plate grade A283 production equipment, auxiliary equipment and testing equipment at home and abroad, more than 260 employees, more than 20 middle and senior management staff, more than 10 professional and technical personnel, annual production capacity of 100,000 tons. Main products: flat steel, steel plate grade A283 steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.
Alloying elements, especially Mn, Ni, Cr, Mo and B (trace elements), can increase the hardenability of the steel plate grade A283 steel, so as to obtain a deeper hardened layer and adopt a slower quenching cooling rate. Alloying elements, especially Si, Mo, V and W, improve the tempering stability of the steel plate grade A283 steel to slow down the tempering softening effect. When the content of W, Mo and V is high, secondary hardening will occur during quenching and tempering, so as to improve the hot hardness of the steel.
