AISI 4145H Seamless Alloy Steel Tube
Short Description:
We supply 4145H Cold Drawn Alloy Steel Seamless Pipes with high strength, excellent toughness, and superior fatigue resistance. Ideal for oil & gas drilling, heavy machinery, and automotive industries.
4145H Alloy Steel Seamless Pipe:
4145H Alloy Steel Seamless Pipe is a high-strength, chromium-molybdenum alloy steel pipe known for its excellent toughness, wear resistance, and fatigue strength. It is typically supplied in a quenched and tempered condition to enhance its mechanical properties, including high tensile and yield strength. This seamless pipe is widely used in oil and gas drilling, heavy machinery, and automotive applications, where superior durability and impact resistance are required. Manufactured to ASTM A519 standards, 4145H seamless pipes undergo precision cold drawing and non-destructive testing to ensure high dimensional accuracy and reliability in demanding environments.
