Your message has been sent to the following suppliers. NOTE 4 — The variations given in this table apply to plates that have a minimum specified tensile strength not over MPa or compara- ble chemistry or hardness. NOTE 2 — Flatness Tolerances for Width — The flatness variation across the width shall not exceed the tabular amount for the specified width.
ASME SA20 SA20M Hot Rolled Steel Plate Thickness – mm
The provisions of The actual test temperature used shall be legibly marked with the following information: NOTE 5 — This table and these notes cover the flatness variations of circular and sketch plates based on the maximum dimensions of those plates.
Please reply me within 24 hours.
Metallurgical Structure thickness permitted, qsme be cause for rejection of the plate, except that, by agreement with the purchaser, the 8. The data is and engineers to use sound engineering judgment when presented in tables of probability that impact properties at using tension test results shown on mill test reports.
Just pay for testing is cheaper then material with guaranteed minimum values. The difference in cooling rate can result in X2.

Unless otherwise agreed upon with the purchaser, it is the responsibility of the manufacturer to select suitable process procedures. If plates are furnished by 9.
NOTE 3 — For specified thicknesses other than those shown, the tolerances for the next higher thickness shall apply. This value shall be based upon the heat analysis.
In addition, for elements that are listed in Table 1 but are not specified or restricted 8. Steel Plate for Boilers and Pressure Vessels contains: Join your peers on the Internet’s largest technical engineering professional community.
D By agreement between the purchaser and the supplier, the heat analysis limit for columbium is permitted to be increased to a value not higher than 0. Pressure vessel and boiler quality steel are commonly used throughout amse oil industry including inshore and offshorethe petrochemical industry and the gas production industry. NOTE 8 — Plates shall be in a horizontal position on a flat surface when flatness is measured.
Class III is Killed with a specified minimum tensile strength of 65 ksi or lower. Vacuum Carbon-Deoxidized Steel sufficient testing at intermediate temperatures to permit plotting a reasonable smooth curve.
