Use a complete material designation
Carbon steel, alloy steel and stainless steel describe broad material families. Provide the actual required designation and mechanical properties instead of relying on appearance or the word stainless.
Review service conditions
Corrosion exposure, temperature, mating materials and loads influence suitability. Selection belongs to the project specification and responsible engineer.
Avoid grade confusion
A material designation, fastener property class and structural bolt grade are different references. Specify the system that applies to the selected part.
RFQ checklist
