Impact tests are typically used to test the temperature toughness of boiler steel plates, hot-rolled steel plates, and alloy steel plates. The commonly used standards are as follows:

 

National Standards:

 

GB/T 229 "Metallic Materials - Charpy Pendulum Impact Test Method": This standard specifies the method for Charpy notched impact tests of metallic materials. It is a basic standard for determining the impact resistance of metallic materials, applicable to various steels such as boiler steel plates, hot-rolled steel plates, and alloy steel plates. It can be used for impact toughness testing at room temperature and low temperatures.

GB 4159 "Metallic Materials - Low-Temperature Charpy Impact Test Method": Specifically aimed at Charpy impact tests of metallic materials at low temperatures. For boiler steel plates, alloy steel plates, etc., used in low-temperature environments, if low-temperature toughness needs to be determined, this standard is often followed for the test, which clarifies the test requirements and operating methods under low-temperature conditions.

 

Product Standards:

 

GB/T 713.3-2023 "Steel Plates and Strips for Pressure Equipment - Part 2: Low-Alloy Steels with Specified Low-Temperature Properties": Applicable to low-alloy steel plates for pressure equipment with a service temperature not lower than -70°C. It specifies the requirements for Charpy (V-notch) low-temperature impact tests of the steel plates.

GB/T 3274-2017 "Hot-Rolled Steel Plates and Strips for Carbon Structural Steel and Low-Alloy Structural Steel": Specifies the technical conditions for hot-rolled steel plates and strips of carbon structural steel and low-alloy structural steel. It includes impact energy testing items and stipulates the toughness indicators of the steel under low-temperature conditions to ensure that the steel can meet the needs of actual engineering.

 

In addition, some industry standards such as JB 4727 "Carbon Steel and Low-Alloy Steel Forgings for Low-Temperature Pressure Vessels" also put forward requirements for the temperature toughness testing of specific types of steel. During specific testing, appropriate standards should be selected based on the application, service environment, and relevant technical requirements of the steel.
