4Cr13 (40Cr13) Stainless Steel Datasheet, Properties

4Cr13 steel (New name:40Cr13) is a martensitic type stainless steel, which has higher hardness than 3Cr13 steel after quenching. The steel has good mechanical processing performance. After heat treatment (quenching and tempering), it has good corrosion resistance, polishing performance, high strength and wear resistance.

Fabrication of nano-TiC functional gradient wear-resistant

Jun 01, 2020 · 1. Introduction. 40Cr alloy steel contains a large amount of Cr and offers reliable wear resistance properties. Thus, 40Cr alloy steel is widely used in heavy machinery gear parts , .Gear components manufactured from 40Cr alloy steel can significantly reduce lifecycle costs and offer extended service life compared to similar components manufactured from carbon steel. Investigation on grinding-induced dynamic This study aims to investigate the metallurgical behavior of high strength alloy steel 40Cr during the grinding strengthening (GS) process. The grindi

The differences between 40Cr and 45# steel steel plate,The

Tempering at a temperature of 550~570, 40cr alloy steel has excellent comprehensive mechanical properties. The hardenability of 40cr alloy steel is higher than that of 45 steel, which is suitable for surface hardening treatments such as What is the quenching and tempering treatment of 40Cr steelSep 26, 2020 · Cr steel should be used for parts with large section size or important quenched and tempered workpieces. But Cr steel has the second type of temper brittleness. For quenching and tempering of 40Cr workpiece quenching and tempering, various parameters are stipulated in the process card. Our experience in actual operation is:
