ASTM A513/A513M Grade 8620 Introduce

ASTM A513/A513M is a standard specification for Electric-Resistance-Welded Carbon and Alloy Steel Mechanical Tubing issued by the American Society for Testing and Materials (ASTM). This standard covers electric resistance welded carbon and alloy steel tubing for use as mechanical tubing. This tubing is used for applications requiring mechanical properties, as well as general-purpose applications. The steel conveyed by this ASTM A513/A513M Grade 8620 is generally referred to as carbon steel, though alloy steel is sometimes included by certain definitions. The majority of ASTM A513/A513M Grade 8620 mechanical tubing is produced using mild hot-roll steel alloys.

Smelting temperature:1188°C - 1876°C

Application:Resistance welding carbon steel and alloy steel mechanical steel pipe
