Download PDF A gas processing facility in Western Colorado was having challenges with building differential pressure across a cold box heat exchanger on the inlet to their cryogenic plant. The plant utilizes Pentair separation equipment to remove desiccant fines downstream of a molecular sieve. The plant contacted Pentair field services when they started to see appreciable differential pressure building on their cold box. Pentair field services were on-site to complete a plant survey and troubleshoot the process in order to determine the cause of the fouling.
It's extremely important to know that the processing of the steel during heat treat is one of the largest successful or detrimental factors in blade steel performance. Along with blade shape and geometry, the knife blade's performance is a result of the knifemaker's understanding of and expertise in steel heat treating process.
While people in this field often generalize the relative performance of steels based on anecdotal tales, amateur testing, and popular gossip, most inferior blade steel performance is based on the geometry of the blade and the processing during heat treat.
Many steels perform well, and properly processed high alloy steels are the very best steels in the modern world. Knife blades warming up to room temperature after cryogenic treatment and aging: Deep Cryogenic Treatment and Aging of CPMCM Hypereutectoid Stainless Steel Incredible high performance, advanced T3 cryogenic treatment on this " Vindicator " Counterterrorism Knife in high molybdenum, hypereutectoid, high alloy stainless steel blade "Because tool steels are generally heat treated to make them adaptable to the intended use by enhancing the desirable Cryo plant datasheet, the behavior of the steel during heat treatment is of prime importance.
I created this page as a service to my community of knife enthusiasts, knife collectors, users, aficionados, and knifemakers. I am certain that after you read this page, you will have a greater understanding of modern, high alloy steels used in the finest knife blades, and how steels are physically processed to achieve the very best knife blades ever made in the history of man.
We are lucky to be alive in a time when this is possible, and when knowledge and research are available for free—for the advancement of mankind—in an instant. What I want you to learn from this page is what modern, high alloy, and stainless steels are, what role they play in the world of fine knives, and how heat treating and processing works in my professional field.
There is a right way to heat treat knife blades, and it has taken me decades to achieve the level of understanding I have in this field. There is always more to learn, and—God-willing—I'll continue this journey until I'm finished with this world.
I want my clients purchasing knives because the knives are the best they can possibly be, and that starts with the finest, most advanced metals and treatments that bring them to the pinnacle of their performance.
What kind of performance am I writing about? The performance of knives is cutting, cleanly, repeatedly, and continually. Simple enough; any piece of sharpened metal or other hard material will cut. The performance issue is then about durability, longevity, and strength.
These characteristics exist not only in the design of the blade, but also in the steel alloy itself, with advanced metallurgy, scientifically treated, for the highest wear resistance, toughness, strength, and corrosion resistance. This is the working end of the knife, the cutting edge, and performance has to be built into the blade alloy and brought to its most effective physical state by processing, typically done by the knifemaker himself.
A knife is not just appearance, it is first about performance, and that starts with an extremely finely-made advanced technology blade. While the other parts of the knife are just as important, this page deals with heat treating and processing modern, high alloy tool and stainless steels, which far surpass traditional lower carbon, lower alloy blade steels by many orders of magnitude and in many distinctive characteristics.
Welcome to what is perhaps the best page about heat treating modern high alloy custom knife blade steels you will find on the internet, and thanks for taking the time to be here. Page Topics A special note about this page: When this page went public, some readers other knifemakers complained about generalizations on the page: I didn't want to create a thesis-style research document, full of footnotes, endnotes, and references; I wanted an easier-to-read casual text.
If you are a person who doubts what you are reading here, please read every single reference below, and then enter the terms you are doubting into any good search engine Google is nice and please do your own research. Then, apply that research to make your own knives. While I'm not a professional technical writer, I am a professional knifemaker, and doing my best to offer reasonable, specific information on how I do what I do and why I do it.
Other knifemakers may post their own research and results on their own sites, backed with their own examples based on their own research and backed with their own successes.In the current "wet" Navy, a "Fleet" is more of an organizational fiction rather than an actual entity.
A group of ships belong to a fleet.
But what is generally encountered at sea is a "Task Force.". A common feature of a cryogenic plant is the separation and/or Liquefaction of Gases at process conditions which may be at elevated pressures, but always involving very low temperatures.
There are many industrial cryogenic processes which operate at temperatures in the region of –°C to –°C at their coldest point, with some . Fukuoka | Japan Fukuoka | Japan. Cryogenic Specimen Preparation Principles Since water occupies up to 90% of some animal and plant tissues it represents a most formidable specimen problem to most Microscopists.
Cryo-SEM is a quick, reliable and effective way to over come these not inconsiderable SEM preparation problems. Additionally the technique is widely used for.
Linde designed its SMOOTHFLO™ family of gas regulators to answer today’s welding and cutting challenges. They are the most advanced in the industry, incorporating several patented ‘world firsts’ for better control over welds and cuts.
