Product Desciption
API standard drill pipe AISI 4145H / Hollow Bar AISI 4145H 120Ksi
1.Material Introduction
AISI 4145H is a chromium - molybdenum low alloy tempered steel. It has improved hardenability and is more is commonly used in the high strength condition with min.110 KSI yield.
2.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.
