ASTM standard for spring manufacturing

ASTM has developed a new standard for cobalt-alloy spring wire.

According to ASTM International member Jan Edwards, springs made from cobalt alloy wire are used in many types of machinery, particularly oil and gas industry equipment. The new standard will outline the melt practices, composition, wire drawing, finish, quality, heat treatment, and mechanical properties.

‘Wire manufacturers will now be able to work to an industry standard,’ says Edwards, vice president of marketing at Elgiloy Specialty Metals. ‘End users will use the standard to specify grade and heat treatment and to know finished properties.’

The organization’s nonferrous metals and alloys committee (B02) developed the standard, which will soon be published as B1011.
