4 igh Temp. Alloy Steel Cast Alloy Steel A217 Grade C12A Neway Gate,Globe & Check valves for servicg high pressure and high temperature power plant To cater for the tendency of creasg power plant temperature and pressure to improve efficiencies and meet other high temperature dustries, Neway had successfully developed cast alloy steel A217 Gr. C12A, the alloy exhibit excellent high-temperature properties based on the formation of a particular microstructure contag submicroscopic carbides, and the alloy is also much more resistant to thermal fatigue that the austenitic staless steel because of its lower thermal expansion ratg and higher thermal conductivity. Table 1 below show the allowable stresses (MPa) of several ASTM materials widely used high temperature dustries, and chemical compositions of C12A are shown below table 2: Table 1 Unit: Mpa Temperature Castgs Forggs C9 C12 C12A F22 F9 F Table 1: ASME code section II allowable stresses. Note: Alloy C12A or F91 provide much higher allowable stresses the temperature range from 482~593 (900~1100 ) Table 2 Basic element Grade C Si Mn S P Cr V N Nb Mo ASTM A217 C12A To realize the required high temperature properties, addition to the acceptable chemical composition and room temperature mechanical properties, a number of metallurgical issues must be properly Ni AL executed cludg deoxidation practices, heat-treatment, weldg process and PT(post weldg heat treatment). Then, the special microstructure can be formed, Below Fig.1, 2 & 3 show the accepted microstructures: Figure 1: Acceptable microstructure (1) of castgs (100X) Figure 2: Acceptable microstructure (1) after weldg. (100X) Figure 3: Acceptable microstructure hot affected zone. (100X) (1) 1. Deoxidization 2. eat treatment To remove dissolved oxygen prior to pourg castgs, small quantities of deoxidizers with high affity for oxygen are added to melted metal so as to combe with the oxygen to form solid oxygen clusion particles. The most coon deoxidizers are manganese, silicon and alumum. Only the proper processg, of course which is very difficult, can assure the fal acceptable proportion microstructure, refer to Fig.1, and the high temperature creep strength. This processg is also one of the critical procedures to ensure the proper microstructure. In order to assure the high temperature properties, we perform strict heat treatment process, cludg heatg time and heat preservation time. 3. eldg & Post-weld heat treatment (PT) To achieve the proper creep resistance and toughness for the high chrome alloy, we make special weld process & PT process, cludg pre-heatg temperature control & weldg filler materials, especially PT, all processes are controlled precisely to form martensite the weld and heat affected zone (AZ). Figure 2 & 3 show the acceptable microstructure weld & AZ. 27
