* Safe working pressure is determined after allowing a suitable factor<br />
of safety based on type of line fluctuation. other Schedules available on<br />
request eg. Schedule 5.<br />
Suitable for use in certain equipment which operates under corrosive conditions.<br />
the low carbon content reduces the chance of intergranular corrosion caused by<br />
carbide precipitation.<br />
An extra low carbon austenitic stainless steel, with corrosion resistance similar to<br />
cpD Stainless 304, but with greater resistance to intergranular corrosion.can be<br />
heated for appreciable periods of time above 500 degrees c without the need for<br />
subsequent solution heat treatment. recommended where high heat input methods<br />
are used and subsequent solution heat treatment cannot be performed.<br />
More resistant to certain corrosive conditions than the standard non-molybdenum<br />
bearing austenitic stainless steels. Suitable where protection is required from<br />
highly corrosive non-oxidising acids. is used for plant and equipment in chemical<br />
manufacture.<br />
An extra low carbon modification for cpD Stainless 316, with similar corrosion<br />
resistance. intended for fabrication where welding without subsequent heat<br />
treatment is required. can be welded in heavy sections without the of intergranular<br />
corrosion (weld decay). Suitable for polishing to a bright finish as required for<br />
pharmaceutical and food processing equipment.<br />
