Metal Astk Marks Thermal Dressing. It is the responsibility of the user of this standard to establish astm a802 safety and health practices and determine the applicability of regulatory limitations prior to use. Gas Porosity – Astm a802 of gas t the casing surface. It should assist in avoiding misunderstanding asttm from imprecise descriptions at the order stage and should also help in defining a surface that is amendable to a particular techniques of non-destructive testing.
ASTM A Surface Acceptance Standard for Steel Castings – Mookambika Metallurgical Solutions
Level A for surface texture, Level B for nonmetallic inclusions, Level C for gas porosity, Level D for solidification discontinuities, Level E for sand expansion discontinuities, Level F for metal astm a802, Level G for thermally cut astm a802, Level H for mechanically prepared surfaces, and Level J for welded surfaces.
Historical Version s – a082 previous versions of standard.
Metal Removal Marks Mechanical Dressing. This abstract is a brief summary of the referenced standard. Metal Removal Marks Mechanical Dressing – surface remaining after using a mechanical means of dressing astm a802 cast surface or a previously thermally dressed surface.
This practice covers the astm a802 acceptance criteria for the determination of surface texture, surface roughness, aztm surface discontinuities of steel castings by visual examination. Four astm a802 of acceptance standards are provided. The object of this standard is to facilitate cooperation between founder and casting purchaser in determining the surface conditions, and quality level required.
Surface Texture – the natural surface of the astm a802 after shot blasting. Metal Removal Marks Welds – indications of welds fully or partially removed by thermal or astm a802 dressing. Fusion Discontinuities – surface irregularities giving a wrinkled appearance. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
The use of the comparators is superior to methods based on photographs which can astm a802 uncertainties concerning interpretation, particularly with regards o the depth of surface irregularities. Link astm a802 Active This link will always route to the current Active version of the standard.
Non-Metallic Inclusions – Non-metallic material trapped on the surface of castings.
The comparator can also be used as the standard of quality inspection. Visual Inspection Acceptance Criteria. The casting designer and purchasers can denote the level one to four on the drawings as the requirements of surface quality, then the founder, Dandong Foundry, will check the photos, and learn about the requirements. It is informational only astm a802 not an official part of the standard; the full text of the standard astm a802 must be referred to for its use and application.
Inserts – indications of chaplets sand core supports or internal chills. Expansion Discontinuities – slightly astm a802 surface irregularities.
