Abstract
As the technology of sintering steels is carried out at different temperatures and conditions, the for-mation of their structure and properties are somewhat different. Proper sintering technology allows the pro-duction of highdensity and high-strength powder steels. In most cases, the reason for the decrease in the pro-perties of powder steels is that the diffusion process, which occurs as a result of low sintering temperatures and low sintering times, is weak or non-existent. As we know, density and many physical and mechanical properties of the product increase as the pores close by dif-fusion during sintering. Proper welding technolo-gy allows the production of high-density and high-strength powder steels. Keywords: sintering; technology; powder; steel; structure; properties; oil; gas; industry.
