Standard materials used in Technifast products are as follows : -

​

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 / C60Pb

Hardenable high carbon steel with chrome content used for through-hardened dowels in the metric range.

​

WS 1.4305 and 303S31

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.
