Manufacturing process and delivery condition:

he tubes are manufactured by a seamless process, both hot finished or cold finished is applicable.

The "hot finished" and "cold finished" condition is left to the discretion of the manufacturer.

Delivery Conditions:

Symbols	Types of delivery condition	Surface Condition
HFD	Hot finished heat treated, descaled	Metallically clean
CFD	Cold finished heat treated, descaled	Metallically clean
CFA	Cold finished bright annealed	Metallically bright
CFG	Cold finished heat treated, ground	Metallically bright-gound, the type and degree of roughness hsall be agreed at the time of enquiry and order
CFP	Cold finished heat treated, polished	Metallically bright-polished, the type and degree of roughness shall be agreed at the time of enquiry and order
a Combinations of the different conditions may be agreed at the time of enquiry and order b The symbols are abbreviation for type of condition. Example: CDF = Cold Finished Descaled c The enquiry and the order shall indicate whether the roughness requirement applies on the internal or external tube surface, or internal and external

Elements not listed in this table shall not be intentionally added to the steel without the agreement of the purchaser except for finishing the cast.All appropriate precautions are to be taken to avoid the addition of such elements from scrap and other materials used in production which would impair mechanical properties and the suitability of the steel. For products to be machined a controlled sulphur content of 0.015% to 0.030% is permitted by agreement provided the resistance to corrosion is still satisfied for the intended purpose. *Option3:A sulphur content of 0.015% to 0.030% is specified***. Where for special reasons,e.g. hot workability it is necessary to minimize the deltaferrite content,or with the aim of low permeability,the maximum nickel content may be increased by 0.50% Where for special reasons,e.g. hot workability it is necessary to minimize the deltaferrite content,or with the aim of low permeability,the maximum nickel content may be increased by 1.00% Where for special reasons,e.g. hot workability it is necessary to minimize the deltaferrite content,or with the aim of low permeability,the maximum nickel content may be increased by 1.50%
