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")
AISI 4145 – 125 ksi, conforming to API 7-1 / API 6A (Ø2"–Ø10")
AISI 4330 – 150 ksi, conforming to API 7-1 / API 6A (Ø2.5"–Ø8.75")
Tubes and bored bars in various dimensions and grades, conforming to NACE MR0175, API 6A, API 5CT and related specifications
Alloy 718 (Inconel 718), conforming to API 6A (Ø0.625"–Ø2.5")
Alloy K-500 (Monel K-500), conforming to API 6A (Ø1.75"–Ø2.5")

Additional materials and specifications can be sourced upon request through our established supplier network.

Threads

Threading & Fatigue Enhancement

DSM AS has extensive experience machining thread forms used in oilfield and industrial applications.
We maintain dedicated software, gauges and tooling to machine and verify a wide range of thread standards.

Typical thread forms include:

API NC – according to API Spec 7
API REG – according to API Spec 7
API FH – according to API Spec 7
API Sharp V tubing connections – NUE and EUE according to API Spec 5A / 5B
PAC connections
Ratchet and Buttress threads

Cold Root Rolling

DSM AS has equipment and established procedures for cold root rolling of thread forms to improve fatigue performance.

Supported profiles include:

V0.038
V0.040
V0.050
H90

Our equipment can apply up to 8 tons of rolling force, enabling controlled strengthening of critical thread roots.

Shot Peening

DSM AS also has experience with shot peening of threads and other geometries where fatigue performance is critical.

Shot peening introduces compressive residual stresses in the material surface, improving fatigue strength and resistance to stress-corrosion cracking.

The process can be applied for selected applications where it forms part of a broader manufacturing scope.

QHSE

DSM AS is committed to delivering high-quality machined components while maintaining safe working conditions and responsible environmental practices.

Our production philosophy is based on controlled machining processes, reliable material supply and careful monitoring throughout the manufacturing workflow. This ensures consistent quality, traceability and dependable performance for components used in demanding industrial environments.

Operations are conducted according to structured internal procedures aligned with ISO 9001 methodology, supporting systematic quality management and continuous improvement.

Quality

Precision machining of high-strength materials requires control of the entire manufacturing process, from raw material to finished component.

Quality assurance activities typically include:

Material certification and traceability from approved suppliers
Verification of dimensions during and after machining
Control of machining processes and tooling setups
Documentation of production steps when required by customer specifications
Final dimensional inspection prior to delivery

For critical components, additional inspection and documentation can be provided according to customer requirements.

Inspection and NDT

Inspection and verification are integrated throughout the manufacturing process to ensure dimensional accuracy and compliance with customer specifications.

Inspection capability includes:

PT – Liquid Penetrant Testing
MT – Magnetic Particle Testing
Hardness verification
Dimensional inspection

DSM AS has in-house ISO 9712 Level 3 competence in PT and MT, enabling qualified evaluation of inspection requirements and procedures.

Dimensional verification is performed using standard precision measuring equipment as well as Renishaw probing systems integrated in our CNC machines, allowing measurement directly in the machine during and after machining operations.

Through extensive practical experience and close integration between CAD/CAM, machining processes and inspection methods, DSM AS is able to verify complex geometries and features using both conventional and specialized measurement techniques.

When required, inspection and testing can be coordinated with certified third-party laboratories, heat treatment facilities and testing institutes, including both non-destructive and destructive testing.
