4130 30CrMo Alloy Steel Pipe Hardware 25crmo4 Seamless Pipe Steel Tube Carbon Steel Tube

Product Description

Product Description
Alloy steels are designated by AISI four-digit numbers. They are more responsive to mechanical and heat treatments than carbon steels. They comprise different types of steels with compositions which exceed the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va in the carbon steels.
AISI 4130 alloy steel is a low alloy medium carbon steel. AISI 4130 steel is commonly referred to as Chromoly steel or chrome moly steel.
