ASTM A512 Grade 1115 Introduce
The ASTM A512 Grade 1115 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 1115 is also flame resistant, meaning that it can maintain its strength under very high temperatures.
Smelting temperature:1113°C - 1111°C
Application:Cold drawn butt welded carbon steel mechanical pipe
ASTM A512 Grade 1115 Material Mechanical Properties
Ductility measures the material's ability to deform, before it breaks. ASTM A512 Grade 1115 steel is a highly ductile material, with an elongation of up to 40%. This high ductility is important for many applications that require the steel to undergo deformation and flexible bending.
