General Carbide highlights use of Sinter-HIP in part production
October 23, 2019
General Carbide, headquartered in Greensburg, Pennsylvania, USA, recently discussed its use of Hot Isostatic Pressing (HIP) in the production of cemented carbide finished products, in a post on its blog. Tungsten carbide graded powder is pressed into shape and consolidated in a process called Sinter-HIP, explained General Carbide.
This thermal consolidation method involves the simultaneous application of high heat and pressure, resulting in a product that is said to contain little or no porosity and is as close as possible to full theoretical density. “HIP produces a finished product that offers the highest level of reliability,” the company states. “At General Carbide, we guarantee sinter-HIP on all parts processed through our furnaces to ensure superior metallurgical quality.”
Subjecting preforms to sinter-HIPing is also reported to improve nominal transverse rupture strength, ranging from 400,000–560,000 psi. The resulting parts and components are said to have little or no porosity and offer superior reliability for applications in automotive, aerospace, heavy equipment, general industry and oil & gas.
