A179 Seamless Steel Tube Description
A179 seamless steel pipe is a commonly used steel pipe material, and its implementation standard is ASTMA179/A179M. This standard applies to seamless carbon steel and alloy steel tubes for heaters, boilers and heat exchangers. the ASTM A179/A179M standard requires that the chemical composition of the pipe meet specific requirements to ensure that the material of the pipe meets specific standards and has good weldability and mechanical properties. From the point of view of mechanical properties, the standard specifies the mechanical performance indicators such as tensile strength, yield strength and elongation of the pipe to ensure that the pipe has sufficient strength and toughness during use.
