The quality of A709 Gr HPS70W bridge steel plate shall not only meet the requirements of the standard, but also be higher or stricter than the product characteristics specified in the standard, including chemical composition, structure, physical properties, chemical properties and other requirements of A709 Gr HPS70W bridge steel plate buyer, such as packaging, delivery time, etc.. On the basis of the quality of A709 Gr HPS70W bridge steel plate in line with the corresponding standards, some buyers will put forward specific requirements according to their own use requirements, which is called technical agreement. That is, some specific factors should be met according to the buyer's requirements. These requirements may be the control of chemical element content of A709 Gr HPS70W bridge steel plate and certain performance limit of A709 Gr HPS70W bridge steel plate, etc.
Spring steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. A709 Gr HPS70W bridge steel plate, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. Spring steel has hot rolled steel, cold drawn steel, cold rolled steel strip and so on. How much a ton of spring steel is related to the grade of spring steel, the market situation and the manufacturer.
Alloy elements have the most significant strengthening effect on steel in quenched and tempered state. The primary purpose of adding alloying elements to steel is to improve the hardenability of steel and to ensure that martensite is easily obtained during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, A709 Gr HPS70W bridge steel plate.
A709 Gr HPS70W bridge steel plate, Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.
