AISI 4130 - chromium molybdenum alloy steel

AISI 4130 - chromium molybdenum alloy steel. A low alloy steel is used in oil patch applications and used widely as an aircraft steel. 4130 is an oil and gas steel grade with a lower carbon content than?4140?giving 4130 improved weldability, the trade off is reduced through thickness strength. 4130 has a low resistance to corrosion.
