Detailed Product Description

ASME SA249 / ASTM A249 Stainless Steel Welded Tubing, Bright annealed , Plain End , TP304, TP304L, TP316, TP316L, TP316H, TP316Ti


A 249 / SA 249: Standard Specification for Welded Austenitic Steel Boiler, Superheater, Heat-Exchanger, and Condenser Tubes


1.1 This specification covers nominal-wall-thickness welded tubes made from the austenitic steels listed in Table 1, with various grades intended for such use as boiler, superheater, heat exchanger, or condenser tubes.
1.2 Grades TP304H, TP309H, TP309HCb, TP310H, TO310HCb, TP316H, TP321H, TP347H, and TP348H are modifications of Grades TP304, TP309S, TP309Cb, TP310S, TP310Cb, TP316, TP321, TP347, and TP348, and are intended for high-temperature service such as for superheaters and reheaters.
1.3 The tubing sizes and thicknesses usually furnished to this specification are 1/8 in. [3.2 mm] in inside diameter to 5 in. [127 mm] in outside diameter and 0.015 to 0.320 in. [0.4 to 8.1 mm], inclusive, in wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.
1.4 Mechanical property requirements do not apply to tubing smaller than 1/8 in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness.
1.5 Optional supplementary requirements are provided and, when one or more of these are desired, each shall be so stated in the order.
1.6 The values stated in either inch-pound units or SI units are to be regarded separately as standard. (A combination of values from the two systems may result in nonconformance with the specification.) The inch-pound units shall apply unless the "M" designation of this specification is specified in the order.

Bright Annealed Tube ASME SA249 TP304

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 Yuhong Special Steel to provide a more consistent superior

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

quenched.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 Holding Group`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 traceability.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.
