S31260 Seamless Stainless Steel Tubing OD 6.35mm-325mm Varnish Surface

ASTM A511/A511M MT304 S31260 Seamless Stainless Tubing For Mechanical Applications

ASTM A511/A511M specification covers seamless stainless tubing for use in mechanical applications where corrosion-resistant or high-temperature strength is needed.

Scope:

1.1 This specification covers seamless stainless steel tube for use in mechanical applications where corrosion-resistant or high-temperature strength is needed. The grades covered are listed in Table 1 and Table 2.

1.2 This specification covers seamless cold-finished mechanical tubing and seamless hot-finished mechanical tubing in sizes up to 12¾ in. [325 mm] in outside nominal diameter (for round tubing) with wall thicknesses as required.

1.3 Tubes shall be furnished in one of the following shapes, as specified by the purchaser: round, square, rectangular, or special.

1.4 Optional supplementary requirements are provided and when desired, shall be stated in the order.

1.5 The values stated in inch-pound units are to be regarded as the standard. Within the text, the SI units are shown in square brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other.
