AISI 4130 4140 4340 4150 Alloy Steel Forged Steel Sleeves For Petroleum Industry

AISI 4130 4140 4340 4150 Alloy Steel Forged Steel Sleeves For Petroleum Industry

Guangda manufactures forged sleeves in a variety of sizes and material grades per client specifications. Forged sleeves can be made by either forging a rolled ring on a ring mill and elongating the height of the wall or by forging a cylinder on the press and punching a hole through the center during the forging process.

Forged sleeves are better for high stress applications and wear environments compared to a cast sleeve. Sleeves save a ton of time for machine shops as they do not have to machine that center hole out and they can still keep the wall thickness, height and material grain structure required to make the end use component as durable as possible.
