The Hammer Is Not the Source of Quality: Rolling Instead of Forging for Large-Diameter Round Bars In the steel industry there is an unwritten rule: when a large-diameter round bar will become a loaded shaft, rod, or pin, it must go to a forging press. Forged, people

How to Determine Ferrite Content in Austenitic Stainless Steel: The Tool Most Buyers Misjudge Austenitic stainless steel combines corrosion resistance, heat resistance, low-temperature toughness, easy formability, and excellent weldability; it accounts for roughly 70% of all stainless steel output. Valve bodies, bonnets, and discs are almost exclusively

Not Every Signal Is a Flaw: Ghost Echoes in Ultrasonic Testing of Powder-Metallurgy Superalloy Rings FGH4096 is a second-generation damage-tolerant P/M superalloy: compared with first-generation alloys it trades some strength for excellent resistance to crack propagation, with a service temperature of 750 °C. A note on designations

Cracks Are a Carbide Problem: Continuous Casting of Cr12MoV Cold-Work Die Steel Cr12MoV is a classic high-carbon high-chromium cold-work die steel with high hardness, high wear resistance, and good hardenability. It is widely used for blanking dies, shearing dies, and cold-forming dies. A note on designations before

Heat Treatment Total Quality Control: The Discipline Behind the Furnace Door Heat treatment changes the microstructure of metal parts to deliver the required mechanical properties and service safety. It is a special process: final quality cannot be fully verified by inspection, because sampling and measurement are always

By Harris | Technical Team, FUSHUN METAL Ultra-Clean and Highly Homogeneous: The Two Battles That Decide Premium Alloy Value “Without superalloys there would be no modern aerospace or gas-fired power generation.” That was the opening line of a keynote delivered in July 2026 at the Third International

By Harris | Technical Team, FUSHUN METAL Semi-Steel Roll Heat Treatment: Why a 1000 mm Roll Neck Bends at 940 °C — and the Four Fixes That Stopped It A semi-steel roll — known as adamite in Western mill practice — is a casting that deliberately sits

By Harris | Technical Team, FUSHUN METAL From Scrap to Spec: The Purification Chain That Makes Superalloy Revert Virgin-Grade A common assumption in procurement circles is that recycled metal is inherently inferior metal. Our position at FUSHUN METAL is the opposite: revert is not worse metal —

By Harris | Technical Team, FUSHUN METAL Superalloy Revert Recycling: The 80% Recovery Standard Most Producers Never Mention A superalloy is not a single material. It is a family of iron-, nickel- and cobalt-based alloys engineered to keep load-bearing strength, oxidation resistance and creep resistance where ordinary
