Abstract

The paper expresses the influence of blasting conditions on the properties of steel sheet RSt 37 – 2 having a the gauge of 3 mm. Due to blasting, the surface roughness increases by an order and the surface strain hardening takes place to the depth of ca 0.06 mm, which results in compressive stress on the sheet surface. The increase of the yield point is more significant if the diameter of the blasting medium (within the tested interval from 0.56 to 0.9 mm) and the impact angle (30 to 75º) are greater at an air pressure of 0.4 – 0.5 MPa.
