tigges materials

We process just about every material, from aluminum to highly acid-resistant stainless steel, to suit a wide variety of operating conditions. Whether it is screws with a particular surface or sea water-resistant connectors for the offshore sector: we combine technical expertise with cost-effectiveness.

All our raw material sources are subject to strict supplier management and detailed test certificates are available for each of material.

Materials overview

The following materials are generally in stock, with others available on request.

AISI ISO SUS (JIS) DIN Description
Stainless steels
302 HQ A2 XM-7 1.4567 Austenitic chromium-nickel steel, highly resistant to corrosion. Due to the additional copper content, it is particularly suitable for cold forming.
304 A2 304 1.4301 Austenitic chromium-nickel steel, highly resistant to corrosion.
316 A4 316 1.4401 Particularly corrosion-resistant austenitic chromium-nickel steel with molybdenum content.
316 Cu A4 316 Cu Similar to 316 with additional copper content to improve cold formability.
316 L A4 316 L 1.4404 Particularly corrosion-resistant austenitic chromium-nickel steel with molybdenum content and with lower carbon content compared to conventional 316.
410 C1 410 1.4006 Heat-treatable, martensitic stainless steel. Polished against water and steam resistant.
430 F1 430 1.4016 Ferritic chromium-nickel steel, mirror polishing, resistant to water, steam, weak acids.
Steel grades
SWRCH6 – SWRCH10 For unhardened screws.
SWRCH1018 Case-hardened, mostly for self-tapping screws.
SWRCH35K/35ACR Heat treatable up to strength 8.8.
