ASTM A240 vs EN 10088-2: How to Read Stainless Steel Sheet Standards Without Losing the Engineering Context
ASTM A240 and EN 10088-2 can describe similar stainless flat products, but the two systems do not control grade names, product scope, delivery condition and inspection language in exactly the same way.
How to Select Between 316L and 2205 Duplex Stainless Steel for Chloride Service
Chloride service is not solved by choosing a familiar stainless grade. This article explains how chloride concentration, temperature, crevice geometry and fabrication practice change the selection path from 316L to duplex or higher-alloyed stainless steel.
Why Stainless Steel Cracks or Burrs During Stamping: A Metallurgical View of Process Control
Stamping defects are rarely caused by material grade alone. Burr height, edge cracking and springback usually reflect the combined effect of work hardening, clearance, tool condition, rolling direction and lubrication.
Pitting, Crevice Corrosion and Stress Corrosion Cracking: How Stainless Steels Fail in Real Equipment
Real corrosion failures are local, geometric and process-dependent. Understanding pitting, crevice corrosion and stress corrosion cracking helps engineers choose alloys and details that survive actual service.
How to Read a Stainless Steel Mill Test Certificate Before Releasing Material to Production
A mill test certificate is more than a chemistry sheet. Buyers should use it to verify standard, heat number, grade, product form, mechanical values, inspection basis and traceability before production starts.
