CS 70 and CK67: Carbon steel which, after hardening and tempering, has excellent strength and fatigue resistance which makes them ideal for spring pins, both coiled and slotted.
AISI 304 and WS 1.4310: Austenitic stainless steel, unhardenable and with low magnetic permeability, used
for both coiled and slotted spring pins where corrosion resistance is needed.
WS 1.3505: Hardenable high carbon steel with chrome content used for through-hardened dowels in the metric range.
WS 1.4305 and 303S31 (A2): Unhardenable austenitic stainless steel with low magnetic permeability used for dowels, grooved pins, taper pins and threaded spacers where corrosion resistant properties are required.
Silver Steel to BS 1407: A through-hardenable high carbon steel used for dowels and small turned parts.
WS 1.4571 and 316S11 (A4): Unhardenable austenitic stainless steel with low magnetic permeability, but with very high corrosion resistance used for dowels.
431S29 (C1): A hardenable martensitic stainless steel used for dowels requiring the maximum shear strength, combined with corrosion resistance.
WS 1.0718 (9SMnPb28): Leaded mild steel used for dowels, taper pins and grooved pins.
S300 Pb: Leaded mild steel used for threaded spacers.
AISI 1010: Low carbon steel used for roll-formed clearance spacers.
WS 1.0503 (C45k): Standard Key steel with a minimum tensile strength of 60 Kg/mm².
