What materials are commonly used for honed tubes?

Common materials include:


Carbon steel (e.g., ST52, 1020, 1045)


Alloy steel (e.g., 4130, 4140)


Stainless steel (e.g., 304, 316)

The choice depends on application requirements such as strength, corrosion resistance, and operating environment.

What is the difference between honed tubes and skived & roller burnished (SRB) tubes?

Honed tubes are finished using abrasive stones that create a precise, cross-hatched surface, while SRB tubes are processed using a cutting tool (skiving) followed by a burnishing roller. Honed tubes generally provide better surface finish and straightness, while SRB tubes can be more cost-effective for certain applications.


What are the standard tolerances for honed tubes?

Standard tolerances include:


Inner Diameter: H8 or H9


Straightness: Typically 1:2000 or better


Wall Thickness: Varies by application but usually within ±10%
