Steel plates and strips for pressure purposes; technical delivery conditions; part 2: unalloyed and low-alloyed steels with specified room temperature and elevated temperature properties

This specification outlines the delivery technical conditions for steel plates and coils intended for pressure applications, specifically focusing on non-alloy and low-alloy grades. The document defines the requirements for assessing mechanical properties at both ambient and elevated temperatures, ensuring materials meet necessary performance criteria for safe operation under pressure. It covers aspects such as tensile strength, yield strength, elongation, and impact resistance relevant to various temperature ranges encountered during service. The standard establishes the testing methods and acceptance criteria applicable to these steel products, facilitating international trade and quality consistency in the manufacturing sector. By providing a clear framework for evaluating material behavior under stress at different thermal conditions, it supports the production of components used in boilers, pressure vessels, and other high-pressure equipment. The guidelines address the specific metallurgical characteristics required for such applications, helping manufacturers and purchasers verify that the supplied steel meets established technical benchmarks for safety and reliability in operational environments.
