For the investment casting process, unfilled wax and fused silica with a zircon prime coat were used for patterns and shell molds, respectively. Dimensions of the die tooling, wax pattern, and casting were measured using a Coordinate Measurement Machine. 17-4 Stainless Steel 630 AlloyGeneral Properties. Alloy 17-4 PH is a precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. The grade combines high strength, hardness (up to 572°F / 300°C), and corrosion resistance. Mechanical properties can be optimized with heat treatment. Very high yield strength up to 1100-1300 MPa (160-190 ksi) can be achieved. 17-4PH / 1.4542 / S17400 - Stainless Steel - Precipitation The 17-4PH / 17/4PH / Euronorm 1.4542 / 1.4548 / Type AISI Type 630 ASTM A693 grade 630 / AMS 5604B / AFNOR Z6CNU17-04 / Din EN X5CrNiCuNb16.4 / JIS SUS630 stainless steel material is NACE MR0175 approved. The Effects of Casting Porosity on the Tensile Behavior of Jun 30, 2015 · The effect of casting porosity on the mechanical behavior of investment cast 17-4PH stainless steel was studied as well as the effect of heat treatment on the alloys sensitivity to casting defects. Interdendritic porosity, formed during solidification and shrinkage of the alloy, reduces the yield strength and ultimate tensile strength roughly in proportion to the reduction in load bearing Stainless Steel Investment Castings Investment CastingsStainless steel has a minimum chromium content of 10.5%, making it more resistant to corrosive liquid environments and to oxidation. However, this is not an absolute. Stainless steel investment castings are corrosion-resistant when used in liquid environments and vapors below 1200°F (650°C) and heat-resistant when used above this Stainless Steel Alloy 17-4PH - Austral Wright

It has excellent corrosion resistance, approaching that of stainless steel grade 304. Designers and engineers often choose the alloy for its high strength, with corrosion resistance superior to most other high strength steels.17-4PH Passivation Problems - Finishing2004. q. we are experiencing severe problems with passivating 17-4ph investment [lost wax] castings. we currently prewash our finished castings with a high alkaline cleaner, then passivate with a citric acid based product at 85 °c. the results achieved are very poor, rust spots appear during drying and stains occur all over the parts.
