When Stainless Foundry & Engineering (SF&E) announced its high chrome white iron alloy capabilities last year, the engineering team was focused on introducing processes and tools to continuously improve iron quality over time. As demand increases for this alloy, the SF&E engineering team is taking on more complex pours while maintaining consistent quality and expected lead times.
A Solid Foundation
The first customer requesting high chrome white iron (25CrFe) was having sourcing issues, which meant SF&E was focused on problem-solving from the start. The metallurgy team invested in a specialized spectrometer to analyze the cast irons and white irons and purchased certified reference materials to ensure they were pouring the material to the correct chemistry. Foundry engineering collaborated with manufacturing and process engineering to develop a new procedure for the processing of iron castings. The use of breaker cores, different riser sleeves, and implementation of a newly purchased abrasive saw drastically improved our front-end efficiency.
