It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. QQ-PC, but also includes a number of alternative asttm treatments.
Rejection and Retest Not all of the following tests are suitable for all grades of stainless steel. This condition may be prevented by chemically treating the parts to remove the iron particles or other a967-055 particles, and then allowing the passive? Such records shall be available for inspection when speci?
By meeting standards set by the ASTM and other organizations, we can ensure consistently-high quality for a broad range of metal parts across many industries. The ASTM A passivation standard applies to the cleaning, passivation and testing of stainless steel parts. Practice A—Water Immersion Test The surface of stainless steel resulting from these treatments is free of scale, free iron, and exogenous foreign matter, and does not require a separate treatment for passivation as de?
An example would be application of Practice C on some lesser-alloyed martensitic or ferritic stainless steels.
The ASTM provides instructions and acceptance criteria for these and other tests that can verify the quality of a stainless aa967-05 passivation operation. Appendix X1 gives some nonmandatory information and provides some general guidelines regarding the selection of passivation treatment appropriate to particular grades of a67-05 steel. Attention shall be given to maintaining adequate volume, concentration, purity, and temperature control appropriate to the size and amount of stainless steel to be treated.
