Product Description

cold rolled 42CrMo aisi 4140 alloy Seamless tube pipe

Grade AISI 4130 is a low alloy steel that contains elements such as chromium and molybdenum added to its allot as strengthening agents. As compared to conventional carbon steels, the AISI 4130 Pipe is more receptive to treatments either via heat or by mechanical means. The low content of carbon in AISI 4130 facilitates superior welding operations.
