Stainless Steel Chemical Composition.
(1) For products to be machined, a controlled Sulphur content of 0.015 % to 0.030% is recommended
(2) Where for special reasons, e.g. hot workability for the fabrication of seamless tubes where it is necessary to minimize the deltaferrite content, or with the aim of low permeability, the maximum Ni content may be increased by 1.50% (m/m).
