According to different strength levels, the ASTM A516 plates are available in four grades: Grades 55, 60, 65, and 70. The most common is Grade 70 or called out A516-70. The maximum thickness of {keyword plates is limited only by the capacity of the composition to meet the specified mechanical property requirements. The mechanical properties such as tensile strength, yield strength, and elongation shall be determined by a tension test for the plates.
The metallurgical quality of spring steel should reach the level of high quality steel. Due to the special requirements of production parts, A514 Gr Q quenched and tempered steel, spring steel must have some characteristics. First, the fatigue resistance of spring steel is good, and it can be restored to its original state after repeated use without deformation. Second, good flexibility. Third, the tensile strength of spring steel is good, under the limit of being stretched, it can be restored without breaking.
For stainless steel plate cutting, the choice of cutting method is determined by the thickness of steel plate. If the thickness of A514 Gr Q quenched and tempered steel stainless steel plate is more than 20 mm, flame cutting is adopted, while the thin plate is suitable for plasma cutting. In addition, if the cutting requirements are relatively high, laser cutting can be used. In addition, if the A514 Gr Q quenched and tempered steel stainless steel plate is used as a billboard, plasma cutting is adopted, Because it uses thin plates.
