SA516Gr60 is produced in electric furnaces from scrap steel, resulting in pure steel. The plate is formed by pouring molten steel, cooling it, and pressing it into a flat sheet. The flat, rectangular plate can be directly rolled or cut from wide steel strip. Steel plate is categorized by thickness as follows: thin plate <8 mm (thinnest 0.2 mm), medium-thick plate 8-60 mm, and extra-thick plate 60-120 mm.
SA516Gr60 Steel Plate Dimensions, Shape, Weight, and Tolerances:
The dimensions, shape, and tolerances of the steel plate must comply with national standards.
The thickness tolerance of the steel plate must comply with the Class B tolerances of GB/T709. Upon request, the plate may be delivered with Class C tolerances of GB/T709.
SA516Gr60 Steel Plate Delivery Condition: The plate is delivered in the normalized condition, or a specific condition may be specified based on technical requirements.
Thickness-wise performance requirements for SA516Gr60 steel plate: Z15, Z25, and Z35.
Non-destructive testing requirements for SA516Gr60 steel plate: Primary, secondary, and tertiary inspection.
Z-Direction Properties of SA516Gr60 Steel Plate
1. What is Z-Direction?
Z-Direction steel: also known as "lamellar tearing resistant steel," commonly referred to as Z-direction properties. In steel structures connected by welds, when the steel plate thickness is 40 mm or greater and subjected to tension along the plate thickness, lamellar tearing-resistant steel (often referred to as "Z-Direction steel") is required to prevent lamellar tearing during welding. Lamellar tearing is a problem with thick plates, so Z-direction properties testing is necessary.
2. Z-Direction Properties and Their Impact on the Steel Plate
Thick steel plates are generally more susceptible to lamellar tearing because the thicker the plate, the more non-metallic inclusions and defects there are, and the thicker the weld, the greater the welding stress and deformation. To address this issue, Z-Direction steel is best used. This type of steel is made from a specific grade of structural steel (called parent steel) and undergoes special smelting and treatment. Its sulfur content is less than one-fifth that of ordinary steel, and its reduction of section is above 15%. The mechanical properties of a steel plate along its thickness (primarily its ductility) are called Z-direction properties. These properties can be determined through tensile testing of specimens and are generally measured by the reduction of area. Z-direction steel plates produced in my country are designated by adding the Z-direction steel grade designation Z25, Z25, or Z25 after the parent steel grade. The number following the Z represents the reduction of area (%).
SA516Gr60 Steel Plate Cutting Process:
Cutting Process: SA516Gr60 steel plates undergo factory inspection and, after meeting all performance requirements, are cut according to the cutting process. Cutting and cutting according to drawings are possible. Generally, CNC plasma cutting or CNC laser cutting is preferred for plates up to 20mm thick. For plates 30mm thick or thicker, CNC flame cutting is typically used to control cutting accuracy and time.
