Match the material to the conditions
Describe moisture, salt or chloride exposure, cleaning chemicals and operating temperature. Corrosion performance depends on the actual environment, joint design and maintenance. A general 304 designation alone does not establish suitability for every application.
For more demanding chloride exposure, include the conditions in your enquiry and review the 316 material guide.
Prepare your enquiry
- Product: standard or drawing, thread diameter, pitch and length where applicable.
- Material: exact grade and material specification required by the project.
- Mechanical requirements: required property class or other specified mechanical requirements, stated separately from the material.
- Supply details: quantity, finish, inspection or batch documents and destination.
