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 A709 Gr HPS100W bridge steel plate 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.
It is easy to confuse ship plate with ordinary steel plate. What are the differences between ship plate and ordinary steel plate? First, compared with the ordinary steel plate, the thickness of the ship plate is thicker and the accuracy is better. Otherwise, it will be broken by the impact of sea water during the operation, which will bring life danger to the personnel on the ship. Second, compared with ordinary steel plate, A709 Gr HPS100W bridge steel plate, the corrosion resistance of ship plate is more outstanding. The ship is immersed in sea water for a long time, if it does not have good corrosion resistance, then the ship plate will rust easily, and the weight of the ship will become larger, and it will also bring pollution to the sea water and cause ecological damage.
In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and A709 Gr HPS100W bridge steel plate pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
