ASTM A512 Grade 1117 Introduce
ASTM A512 is a steel standard issued by American Society for Testing and Materials (ASTM), an international standards organization that develops and publishes technical standards for a wide range of materials, products, systems, and services. This steel standard describes the requirements and characteristics of cold-drawn mechanical steel tubing. Manufacturers that produce cold-drawn tubing used in basic applications such as hydraulic cylinders, hydraulic lines, and air conditioning components must adhere to the specifications detailed in the ASTM A512 steel standard.
Smelting temperature:1568°C - 1759°C
Application:Cold drawn butt welded carbon steel mechanical pipe
