It is a general guide for customers to theproducts and services available from ATLAS STEELS and no representation is made orwarranty given in relation to this information or the products or processes Grade 304 and 316 design pressures are only valid at temperatures above 538 C ifcarbon content is or Allowable working pressures are given in megapascals (MPa).

2 Conversions to otherunits are:1. This data is intended to provide a general guide. It must not to be relied upon in theabsence of competent professional These allowable pressures were calculated by the formula given in AS 4041-2006" Pressure Piping", clause Other design codes may give different allowablepressures. The original specifications must be consulted for full These calculations assume Piping Class 1 so only apply if this level of pipingconstruction quality has been Calculations are for seamless pipe to specification ASTM A312/A312M.
