Customer Case of Investment Casting

The commonly used stainless steel material in Sieg-Huao includes 304, 316,316L and 17-4PH among which 17-4PH is much special.

17-4 PH is a martensitic, chromium-nickel-copper precipitation-hardening stainless steel. 17-4 PH stainless steel is capable of attaining a wide range of strength and toughness properties depending on the precipitation or aging temperature used in hardening.  Its valuable combination of high strength, good corrosion resistance and toughness in both base metals and welds gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. High strength is maintained to approximately 600°F (316°C). This material has good resistance to stress corrosion cracking in the lower strength conditions. 

 

Common Applications of 17-4 PH Stainless Steel

·Aerospace applications

·Fasteners

·Base plates

·Chemical processing equipment

·Oil and petroleum refining equipment

·Nuclear components

·Food grade stainless steel for processing equipment

·General metalworking applications that call for precipitation-hardening stainless steel

The smallest investment casting part we had produced in 17-4PH only weights 2g. It is supplied for one of the biggest door and window hardware manufacturer in Germany, Europe. Small weight is usually a challenge  because it’s easy to deform during production process. You may have a direct feeling about this part with so small weight from below pictures:
