Pre-treatment of stainless steel forgings

Pre-treatment is a crucial process before the surface of stainless steel forgings enters surface treatment (including pickling passivation, electropolishing and electrochemical polishing, electroplating, passivation, blackening, coloring, chemical processing, etc.). During the processing of stainless steel forgings, the surface may be contaminated with oil stains, burrs, uneven surfaces, and metal oxides. Therefore, before surface treatment, it is essential to remove oil stains, burrs, uneven surfaces, and metal oxides to ensure satisfactory results in subsequent processing.

A Brief Discussion on the Heat Treatment Precautions of Wear-Resistant Alloy Steel

Wear-resistant alloy steel mainly improves its performance by adding elements such as Cr, Mo, V, Ti, and rare earth elements to traditional high-manganese steel, with Cr being particularly widely used. During the work hardening process of high-manganese steel, dynamic variational aging is formed, namely C-Mn atom pairs, which have the effect of expanding the clustering of C-Mn ordered atom pairs in high-manganese steel. This paper studies the changes in microstructure, structure, resistance, and wear resistance of wear-resistant alloy steel and ordinary high-manganese steel with different tempering temperatures. The results show that under the condition of relatively low carbon content, wear-resistant alloy steel is superior to ordinary high-manganese steel in wear resistance. Moreover, the microstructure of alloy high-manganese steel varies with the tempering temperature, resulting in different wear resistance.
