AISI 4145 Alloy Steel

AISI 4145 is a chromium molybdenum alloy steel grade widely used in the oil and gas sectors.

Similar to AISI 4140 but with a higher carbon content. 4145 is more popular in larger diameters due to its increased strength and hardenability. AISI 4145 is commonly supplied quenched and tempered with a hardness of between 30 to 36HRc.

AISI 4145H is a chromium – molybdenum low alloy tempered steel.

AISI 4145H has improved hardenability and is more is commonly used in the high strength condition with min.110 KSI yield. Similar to AISI 4140 but with a higher carbon content. 4145 is more popular in larger diameters due to its increased strength and hardenability.
