At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to ASTM A693. Standard specification for precipitation-hardening stainless and heat-resisting steel plate, sheet and strip. A flat-rolled product spec (not a washer standard); used for PH-stainless flat parts, and its grades/tempers characterize the 17-4/17-7 family also used for high-strength stainless fasteners.
