The six-part ISO 3506 series covers every type of stainless steel fastener. It provides additional advice and guidance for most applications where these products will be required.
The series applies to testing at the ambient temperature range of 10C to 35C and also includes advice on special fasteners for high temperature applications.
It also specifies property classes in relation to austenitic, martensitic, ferritic and duplex (austenitic-ferritic) steel grades for fasteners.
