Structured knowledge on grades, standards, processing, applications and trade compliance
How chloride exposure, temperature and maintenance decide between 304, 316L and duplex grades.
Certificates, traceability, inspection reports and what to verify before the first order.
The same tonne of stainless has three different cost structures depending on the form you buy.
Nominal thickness is not a promise — the acceptance range is.
Why heat tint must be removed and how to specify cleaning after welding.
Methods A, B and C, how test conditions differ from service, and the limits of the result.
Adjust focus, speed, gas pressure and nozzle condition in a defined order.
Ferrite-austenite balance, filler selection and practical welding windows.
7219 versus 7220, hot versus cold rolled, and common classification mistakes.
CN codes, production routes, direct and indirect emissions, and verification requirements.
Heat number, chemical composition, mechanical properties, heat treatment and signatory.
Three cases where it is mandatory, two where it can be simplified, plus alternatives.
Material, tooling and process approaches to compensate springback, with typical values for common grades.
Check gas supply, base metal, filler, parameters and environment in that order.
Chloride exposure, welding, hygiene requirements and lifecycle cost decide whether 316L is mandatory.
