The subclauses marked with a two dots give specifications which optional and may be agreed upon at the time of ordering.

1. Field of application

1.1 This standard applies to general purpose seamless circular tubes and pipes (hereinaiter briefly referred to as tubes) made from the stainless steels listed in table 1. They are used. for example as construction tubing, a pipes for the fodd. pharmaceutical and automobile inoustries. and as pipes for domestic installation nd for decorative purposes.

Tubes conformming to ilre lequirernents o this stardard are intanded to be used on the basic of an 80% utilization of the permissble design stress in weld.

1.2 This standard does not apply to general purpose welded circular austenitic stainless steel tubes subject to special requiremnets (see DIN 17458).

n1	Cold redrawn tubes free from scale (polished-drawn), not heat treated	Metallically polished-drawn, smoother than for condition h or m	Tubes complying with this condition are somewhat harder than those of condition h or m and their mechanical properties are modified. These tubes are especially sultable for grinding and polishing.
n2	Cold redrawn (polished-drawn), bright heat treated	Metallically bright-annealed, smoother than for condition h or m	Especially suitable for grinding and polishing.
o	Ground	Metallically bright-ground; the type and degree of grinding shall be agreed at the time of ordering.	Conditions h, m or n2 are generally used as starting condition 2).
p	Polished	Metallically bright-ground; the type and degree of grinding shall be agreed at the time of ordering.
1) See also subclause 5.2. 2) The order shall specify whether griniding or polishing is to be internal or external. or internal and external.

5.8.2. The tubes shall have an inside and outside surface consistent with the manufacturing process used.

5.8.3. Slight irregularities in the surface resulting from the manufacturing process, such as raised or depressed areas or shallow grooves are permitted, except for condition P(polished), as long as the remaining wall thickness fulfils the requirements specified in subclause 5.10 and the function of the tubes is not impaired.

5.8.4. Proper removal of surface defects using appropriate means (e.g. grinding) is permitted as long as the remaining wall thickness fufils the requirements specified in subclause 5.10.

5.9. Leak tightness

The tubes shall remain leaktight when testedes specified in subclause 6.5.5.

5.10. Dimensions, masses per unit length and permissible deviations

DIN 2462 Part1 shall apply for the dimensions and masses per unit length of tubes and for permissible deviations.

DIN 11850 shall apply for tubes intended for use in the food industry. The order shall follow the pattern of the sample order given in that standard.

5.11. Physical properties

Reference is made to volume 10 of the Stahleisen-Sonderberichte (Iron and steel special reports)(see the "Stanoards and other documents referred to clause) for guideline data on the physical properties of the steels conforming to the requirements of this standard.

As the symbols or the steel grades differ from those specified in DIN 17 440. December 1972 edition, following the specifications for the chemical composition, and in ccordance with DIN 17 440. July 1985 edition, a compilation of the material numbers, which have not changed, and the previous and new symbols is given below in tabular form. It shall be noted that the symbols used in DIN 17 440. December 1972 edition. may still be used during the period of validity of this standard.
