Description
Alloy AISI 4145 Steel Round Bar
Compared with AISI 4140, AISI 4145 is a chromium molybdenum low alloy steel grade widely used in the oil and gas sectors but with a higher carbon content. AISI 4145H and 4145H MOD are the upgraded type of AISI 4145.
Relevant standards:
ASTM A29, ASTM A322, ASTM A331, ASTM A505, ASTM A519, SAE J404, SAE J412, SAE J770, UNS G41450
Size of supply:
Diameter : 80mm To 800mm
Length: 1000 mm Long To 6000 mm Long
Finish: Bright, Polish & Black
Application:
AISI 4145 is more popular in larger diameters due to its increased strength and hardenability. It is commonly used in the down hole drilling tools such as drill collars. Other applications include components exposed to heavy strain, such as shafts, gear, bolts etc. AISI 4145H can also be used in hardened condition as machine parts exposed to heavy wear.
