4Cr9Si2 Chemical Composition, Mechanical Properties,

also contains the use of 4Cr9Si2,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application. Data Table for Grades Stainless Steels - Special Steels Valve steel bars for internal combustion engines - Technical requirements 4Cr9Si2 4Cr9Si2 Standard Number ITEM Standard Number Descriptions A comparison of wear behaviour of heat resistant steel reductions through the use of traditional heat resistant steel or nickel-base or cobalt-base super alloys. Thus, TiAl alloy is becoming a potential material with its low density and excellent mechanical properties at elevated temperatures, albeit with higher raw material and manufacturing costs [3].

A new method for manufacturing hollow valves via cross

Feb 01, 2017 · Fig. 2 shows the grain size of 4Cr9Si2 after annealing. Cylindrical specimens with a diameter of 8 mm and a height of 15 mm were machined from the wrought billet. The constitutive relation of material was determined through linear regression. The equation is written as follows (Eq. ):(2) = e 31.25 [s i n h (0.00758 )] 4.9535 exp Characterizations of 21-4N to 4Cr9Si2 stainless steel A new welding process, electric-resistance-heat-aided friction welding (ERHAFW), was introduced in this study. To further improve the joint quality and energy-saving, electric resistance welding was combined with the conventional continuous-drive friction welding. 21-4N (austenitic stainless steel) and 4Cr9Si2 (martensitic stainless steel) valve steel rods of 4 mm diameter were used as base

Characterizations of 21-4N to 4Cr9Si2 stainless steel

Dec 01, 2009 · The 4Cr9Si2 steel was in a quenching and tempering state with a microstructure of tempered sorbite (1040 °C for 10 min, oil quenching; 760 °C for 60 min, oil tempering). The compositions of these two steels are given in Table 1. The dimensions of specimens are illustrated in Fig. 4. The diameter of weld face is 4 mm. Characterizations of 21-4N to 4Cr9Si2 stainless steel W.-Y. Li, Yu, Li, Zhang, & Wang [13] developed a friction heat-assisted electric arc welding process to join austenitic stainless steel (21-4N) and martensitic stainless steel (4Cr9Si2) from 4 mm
