[Industry Encyclopedia] Differential Promotion Strategies for 300-Series and 400-Series Stainless Steel & Downstream Demand Matching
2025-12-21

Stainless steel, as a versatile material, dominates global manufacturing and construction sectors, with 300-series and 400-series being the two most widely used categories. While both offer corrosion resistance and durability, their core properties—such as alloy composition, cost, and performance—di Read More
[Industry Encyclopedia] 304 Stainless Steel Casting Repair Welding (ER308L Wire) and Air Tightness Testing
2025-12-21

304 stainless steel castings are widely used in automotive, aerospace, petrochemical, and food processing industries due to their excellent corrosion resistance, good mechanical properties, and cost-effectiveness. However, casting defects such as porosity, shrinkage cavities, and cracks are inevitab Read More
[Industry Encyclopedia] Stainless Steel Medical Device Sterilization Tolerance: Performance Stability of 316L Under High-Temperature and High-Pressure (134℃/0.2MPa) Steam
2025-11-15

Medical devices such as surgical forceps, endoscope components, and implantable tools demand rigorous sterilization to prevent cross-infection. High-temperature and high-pressure (134℃/0.2MPa) steam sterilization is the gold standard in healthcare, as it effectively eliminates bacteria, viruses, and Read More
[Industry Encyclopedia] Stainless Steel Bridge Anti-collision Guardrail Processing: Bending Angle (90°-135°) Control and Surface Treatment of Hot-rolled 304 Steel Plate
2025-11-15

Bridge anti-collision guardrails serve as the last line of safety for vehicles and pedestrians, requiring both robust impact resistance and long-term corrosion resistance. Hot-rolled 304 stainless steel plate, with its 18% chromium and 8% nickel composition, has become the preferred material for suc Read More
[Industry Encyclopedia] Stainless Steel Coil Bending Challenges: 304L Hot Bending Temperature (200-300℃) Control and Ovality (≤5%) Assurance
2025-10-28

Walk into a food processing plant or a chemical factory, and you’ll spot 304L stainless steel coils everywhere—they carry hot liquids, coolants, and even corrosive chemicals. But turning a straight 304L stainless steel tube into a coiled shape isn’t as simple as it sounds. Two big problems trip up m Read More
[Industry Encyclopedia] Density Improvement of Stainless Steel Powder Metallurgy Parts
2025-10-28

Walk into a hardware factory, and you’ll find stainless steel powder metallurgy parts everywhere—from small gears in power tools to valve cores in plumbing fixtures. These parts are made by pressing stainless steel powder into a mold and then heating it (a process called sintering) to bond the parti Read More
[Industry Encyclopedia] Stainless Steel Flange Seal Failure Analysis: Performance of Different Gasket Materials (Graphite/PTFE) Under High Temperature and Pressure
2025-10-21

Stainless steel flanges are everywhere in industrial plants—connecting pipes in oil refineries, holding together reaction vessels in chemical factories, and sealing steam lines in power plants. But here’s a quiet problem that costs factories millions every year: seal failure. A single leaky flange c Read More
[Industry Encyclopedia] Stainless Steel Wire Quality Control: Composition Uniformity (Cr/Ni Deviation ≤0.5%) and Welding Spatter Control of ER308L
2025-10-12

ER308L stainless steel wire is the workhorse of stainless steel welding—used to join 304/304L stainless steel in everything from food processing tanks (where corrosion resistance matters) to chemical pipelines (where weld strength can’t fail) and medical equipment (where precision is non-negotiable) Read More
[Industry Encyclopedia] Aging Treatment Parameter Optimization and Sealing Surface Machining of 630 Stainless Steel for Valve Cores
2025-09-25

Think about a valve in a high-pressure water pipeline or a chemical plant—its ability to stop leaks all comes down to the valve core. This small, often overlooked part controls fluid flow by pressing its “sealing surface” against the valve seat; if the core is too weak, it bends under pressure, and Read More
