ASTM A512 Grade 1012 Introduce
The ASTM A512 Grade 1012 steel is composed primarily of carbon and alloy elements, though it may also contain elements such as molybdenum, manganese, or chromium. This steel type has excellent tensile strength, as well as a high level of ductility and machinability. It is alloyed with oxygen and nitrogen to minimize grain boundaries and create a strong and uniform grain structure. ASTM A512 Grade 1012 is also flame resistant, meaning that it can maintain its strength under very high temperatures.
Smelting temperature:1573°C - 1467°C
Application:Cold drawn butt welded carbon steel mechanical pipe
