To ensure the highest surface quality in all of our sanitary tubing,Yuhong Special Steel goes beyond 

the requirements of ASTM A269 and A270 by performing the full battery of ASTM bend and deformation

tests required by ASME SA249 as well as additional deformation tests developed by Yuhong Special

Steel. The tests, combined with specific raw material requirements, Eddy Current testing at the tube mill, 

and tighter OD and wall tolerances allow Zhongzhou Special Steel to provide a more consistent superior 

quality product.Hydrogen bright annealed in line to 1900°F (1040°C) minimum and rapidly enched.Surface 

finish is 20 μ-in Ra (0.5 μm) ID maximum, 30 μ-in Ra (0.8 μm) OD maximum surface roughness measured 

per ASME/ ANSI B46.1 with the profilometer reading at 90 degrees to major polishing pattern. Yuhong

Special Steel’s polishing techniques result in surface finishes that lead the industry. All tubing is printed with 

size, gauge, alloy, ASTM and ASME specifications, heat number and date of manufacturing for full

raceability.As a final step in maintaining purity standards, Yuhong Special Steel’s A270 S2 tubing is 

packaged using protective 2 mil poly sleeving along with air tight plastic end caps. The tubing is then

 placed in triple wall boxes for maximum protection during shipment. Other packaging is available on 

request.
