Almen (Almen) tee shot steel strength test commonly used N test piece (test for non-ferrous metals), A test piece (the most common), C specimen (higher intensity) to be measured, A and C test pieces the relationship between the test piece is approximately three times the relationship. As measured by C specimen strength 0.15-0.20C mm equivalent 0.45-0.60A mm. The figure for the C-thick test piece for A thin specimen. During the test, the first measurement of the original specimen deformation, and the card is good in the test piece tooling placed inside a stainless steel tee shot, using the same process with the workpiece is injected. Shot over, remove the test piece stainless steel tee, measuring deformation arch height. Tee shot blasting coverage coverage means that every point on the number of steel shot was hit piece, someone shot coverage often think: My lower spray nozzle 1 1 work 2 times, you can not meet 200% of the coverage it? first I feel justified, in fact not the case. Coverage measurement is as follows: first the surface coated with a fluorescent glaze or glaze, and then press the shot peening process parameters on the workpiece, spraying the surface of each workpiece is removed again, observed under a microscope (magnifying glass) the residual The proportion of coating on the surface, as well as 20% of the residue, the coverage was 80%. When the residual only 2% wrought stainless steel tee, namely coverage of 98%, it can be regarded as clear that 100% coverage, then there is a time. If it reaches 400% coverage, which is 4 times the time. Factors 16 5. Coverage of Hebei Chiho Pipe Stone its main material for stainless steel, stainless steel and other materials exposed to the atmosphere, like stainless steel will be dirty. Future lectures will analyze the costs of repair and cleanup design factors. However, in the rain erosion, there is also a correlation between artificial flushing and dirty surfaces. Determine the effect of rainfall through the same plank directly on the atmosphere and on the Covered areas. Artificial flushing effect is achieved by artificial scrub with a sponge with soapy water for six months the right side of each strip determined intervals. The results showed that, compared with the slats placed Covered places and places not to be flushed by water erosion and manual cleaning to remove surface dust and siltation of surface conditions have a good effect. But also found that the seamless stainless steel tee, also affect the status of surface processing, surface smooth rough planks slats surface area is better. So wash interval is influenced by many factors, the main factor is the aesthetic standards required. Although many steel curtain just flush when the windows, however, in general, for external stainless steel wash twice a year.
