To make fusion reactors, we need materials that can withstand its punishing environment, and a new Chinese-made material can survive reactors’ intense conditions. Here’s what you’ll learn when you read this story: * The central solenoid is the heart of a fusion reactor, and a "jacket" of meticulously crafted stainless steel—capable of withstanding extreme temperatures and magnetic fields—protects it. * Chinese scientists say that a new super steel, called China high-strength low-temperature steel No. 1, (CHSN01), can operate at a maximum of 20 Tesla, which outperforms the steel jacket that will be used by ITER. * China is incorporating CHSN01...

Enhanced 3D printing techniques now allow for the production of 17-4 PH stainless steel, optimizing its strength and corrosion resistance. This achievement marks a significant step forward in the additive manufacturing of complex alloys. Credit: SciTechDaily.com =============================================================================== Using advanced X-ray techniques, scientists have achieved a significant milestone in 3D printing by producing 17-4 PH stainless steel with superior strength and durability. This development promises to lower costs and increase production flexibility, offering profound implications for manufacturing complex materials. Breakthrough in 3D Printing of Stainless Steel Researchers have developed a reliable method to produce a specific type of stainless steel, 17-4...

~snip~ The details behind the new fuel cell The new fuel cell uses stainless steel in place of platinum and rare metals. Johanna Wellington, advanced technology leader at General Electric Global Research and the head of General Electric's fuel cell business, states: "The cost challenges associated with the technology have stumped a lot of people for a long time. But we made it work, and we made it work economically. It's a game-changer. The new fuel cell can generate electricity at any location with a supply of natural gas. It can get going quickly, does not need new transmission lines...

Stainless steel pans are the workhorse cookware in most restaurants. But yours are probably just sitting there, neglected after your last attempt to fry a chicken breast somehow glued the poultry to the metal, resulting in a mangled meal and a burnt-on ring of carbonized protein firmly stuck to the bottom of the pan. “There’s got to be a better way!” you exclaim, as if on your own real-life infomercial. And I assure you there is: using science and proper heat management, you can exploit the Leidenfrost effect to give your stainless steel cookware non-stick superpowers. We don’t want to...

Archaeologists have found what they think is evidence of low-chromium crucible steel in the 11th century in what is now Chahak in Iran, a long time and a long way away from the European Industrial Revolution. The metal would have been used to manufacture armour and weapons, including swords and daggers. "This research not only delivers the earliest known evidence for the production of chromium steel dating back as early as the 11th century CE, but also provides a chemical tracer that could aid the identification of crucible steel artefacts in museums or archaeological collections back to their origin in...

We do have a great materials group, but initially we will simply use high-quality 301 stainless.... For ascent you want something that’s strong at cryogenic temperatures. For entry, you want something that can withstand high heat. So the mass of the heat shield is driven by the temperature at the interface between the heat shield tiles and the air frame. Whether it’s mechanical or if it’s bonded on—whatever the interface point is—determines the thickness of the heat shield. But steel, you can do 1500, 1600 degrees Fahrenheit. With steel, now you’ve got something where you can comfortably be at a...

WASHINGTON, Sept. 12 (Xinhua) -- The U.S. Commerce Department on Monday announced its preliminary affirmative determination in the antidumping duty investigation against imports of stainless steel sheets and strips from China, signaling that it may pose punitive duties on the products. The department said that such products from China had been sold in the United States at dumping margins of 63.86 percent and 76.64 percent. As a result of the preliminary affirmative determinations, the Commerce Department will instruct U.S. Customs and Border Protection to require cash deposits based on these preliminary rates. The Commerce Department launched antidumping duty and countervailing...

Police in a U.S. town bordering Mexico have apprehended an undocumented, Middle Eastern woman in possession of the region’s gas pipeline plans, law enforcement sources tell Judicial Watch. Authorities describe the woman as an “Islamic refugee” pulled over during a traffic stop by a deputy sheriff in Luna County, New Mexico which shares a 54-mile border with Mexico. County authorities alerted the U.S. Border Patrol and the Federal Bureau of Investigation’s (FBI) Joint Terrorism Task Forces (JTTF) has been deployed to the area to investigate, sources with firsthand knowledge of the probe confirm. The gas pipeline plans in the woman’s...

A Middle Eastern woman was caught surveilling a U.S. port of entry on the Mexican border holding a sketchbook with Arabic writing and drawings of the facility and its security system, federal law enforcement sources tell Judicial Watch. The woman has been identified as 23-year-old Leila Abdelrazaq, according to a Customs and Border Patrol (CPB) report obtained by JW this week. Abdelrazaq appeared to have two accomplices, a 31-year-old man named Gabriel Schivone and a 28-year-old woman named Leslie Mcafee. CBP agents noticed the trio "observing the facilities" at the Port of Mariposa in Nogales, Arizona on December 2. Schivone...

As the company, also known as Antam, sells 50% of its annual nickel production to Europe, it watches warnings from European steel makers keenly, but...
