AISI 4145 Steel is defined as Cr-Mo series alloy steel as per USA standard ASTM A29.Like AISI 4130 steel, it is widely used in the oil and gas industry.Compared with AISI 4140 steel, AISI 4145 has a higher carbon content, which means higher strength and hardenability.
AISI 4145 steel is usually used in the quenched and tempered condition, and can be used for oil drill collars, shafts, spindles, and high-load control wheels, bolts, studs, gears, etc.
AISI 4145 Steel Round Bar
AISI 4145 steel is mainly used in the production of oil drill collars, and can also be used in the production of oil casing, which are used in corrosive environments in oil fields.
The good structure of AISI 4145 steel (tempered sorbite) can improve the corrosion resistance. In addition, the alloying element Cr can be dissolved in F, which can improve the corrosion resistance, and the Mo element also helps to improve the corrosion resistance.
