ALTA SPECIAL STEEL supply DIN 1.7225 / AISI 4140 in round bar, especially for BIG ROUNDS!

1.7225 is a chromium molybdenum alloy steel specification widely used in the oil and gas industry. Similar to grade AISI 4130 but with a slightly higher carbon content. The higher carbon content of AISI 4140 gives greater strength and heat treatment capabilities in comparison to AISI 4130, however it does have inferior weldability characteristics.
