What is EN 10216-4
EN 10216-4 is the 4th part of the technical delivery conditions for seamless steel tubes for pressure use published by the German Institute for Standardization (DIN), which specifically involves non-alloy and alloy steel tubes with specified low-temperature properties. This standard specifies in detail the technical delivery conditions for seamless steel tubes for pressure use in low-temperature environments, including special performance requirements such as low-temperature impact toughness.
Common grades include:
P215NL: This is a non-alloy steel suitable for seamless steel pipes used under low temperature conditions.
P255QL: This is also a non-alloy steel, with special considerations for low temperature and low alloy requirements.
P265NL: This is also a non-alloy steel used for steel pipes that require low temperature performance.
26CrMo4-2: This is an alloy steel grade suitable for applications that require higher strength and low temperature performance.
11MnNi5-3 and 13MnNi6-3: These are specific alloy steel grades, usually used to manufacture steel pipes that require a combination of mechanical properties and low temperature performance.
