We are professional AISI 4145(AISI 4145H,AISI 4145H MOD)Forged Forging Steel Drill Collars/Drilling Pipes factory from china
AISI 4145 low alloy steel containing 0.20% Molybdenum is widely used particularly throughout oil patch applications. Similar to 4140 which has a lower carbon level it has improved hardenability and is more is commonly used in the higher strength ?110 KSI 0.2% PS condition.
Larger diameters are often supplied with higher Molybdenum level, 0.35% max and may be referred to as a "Drill Collar" analysis.
The hardenability limitations of this grade (depth to which it will harden / obtain the specified mechanical properties after heat treatment) must always be taken into account when designing and selecting equipment.
