Materials
Through a well-established network of trusted suppliers, DSM AS sources high-quality materials in accordance with a wide range of international specifications and industry standards.
We have solid experience working with high-strength alloy steels, tool steels and corrosion-resistant alloys used in demanding industrial environments. Through close collaboration with material suppliers, mills and heat treatment partners, we help ensure that materials are delivered with the required properties, documentation and consistency for the intended application.
To support efficient production and short lead times, we also maintain a stock of commonly used materials for oil & gas applications. This allows us to respond quickly to customer requirements and ensure reliable delivery when time is critical.
Our stock typically includes:
-
AISI 4140 – 80 ksi, conforming to API 7-1 / API 6A / NACE MR0175 (Ø2"–Ø12.25")
-
AISI 4145 – 110 ksi, conforming to API 7-1 / API 6A (Ø2"–Ø12.25")
