ASTM A514 steel is mainly used in places where high tensile strength and high yield are required, such as engineering vehicle lifting gears, large excavators, offshore platforms, etc. Different grades of A514 steel plate have different thickness, chemical composition and properties. However, the A514 grade Q quenched and tempered steel mechanical properties specified in ASTM A514 are similar to those of Q690 in China. A514 grade Q is generally used as the rack for offshore platform. Its hardness is between 230-390MPa, yield is greater than 630MPa, and tensile strength is more than 700MPa.
For a ship, the choice of medium and thick ship plate is very important, it is an important part of the ship frame. The pressure bearing capacity of A514 grade Q quenched and tempered steel, medium and thick ship plates is very strong. Secondly, because it is a ship plate, it must be driven in water, so of course the corrosion resistance is better, otherwise it will bring danger to buyers. Moreover, the service life of the ship will be increased. Regular inspection of the ship plate can ensure the safety of sailing. You can also know whether the ship plate is defective, so you don't have to worry about water seepage when you sail.
TMCP process is an indispensable technology for our production of low alloy high strength wide and A514 grade Q quenched and tempered steel thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy A514 grade Q quenched and tempered steel and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
