Decomposition Processes of .DELTA.-Ferrite during Continuous Heating in a 25Cr-7Ni-0.14N Stainless Steel.

Colossal Carbon Supersaturation of Delta Ferrite in 17-7 PH Stainless Steel

Low processing temperatures allow an interstitially-hardened case to be formed on the alloy with no carbide formation [1]; a “colossal” carbon supersaturation can be achieved in austenitic stainless steels such as the 316L grade [1, 2]. In addition to the notable mechanical property improvements [3, 4], such interstitially-hardened stainless steels show surprising improvements in corrosion resi...

Quantification of metal release from stainless steel electrodes during conventional and pulsed ohmic heating

Analysis of Stainless Steel Bipolar Plates Micro-Stamping Processes

Bipolar plate is one of the key components of proton exchange membrane fuel cells (PEMFC). Since the production costs of traditional graphite bipolar plates are very expensive and need a few millimeters thickness over the space, the resulting metal bipolar plate not only reduces the cost of such a bipolar plate, the thickness can also be reduced to micron range. This study aims to explore the a...

Stainless Steel Laser-drilled Screens for Continuous Centrifugals

Stainless steel laser-drilled screens (SSL screens) for continuous sugar centrifugals are compared with several types of chrome/nickel screens. Assessments are made of trials and routine operations at several factories around the world, and results of final molasses purity analyses, screen service life, and centrifugal capacities are examined. A semi-quantitative comparison is made between Aust...

Ferrite and austenite phase identification in duplex stainless steel using SPM techniques

It can be challenging to properly identify the phases in electro-polished duplex stainless steel using optical microscopy or other characterization techniques. This letter describes magnetic force microscopy to properly identify the phases in electropolished duplex stainless steel. The results are also confirmed PM anoindentation with the current sensing atomic force and scanning Kelvin probe f...
