Materials Expertise for Certified Fasteners & Machined Components
Support across carbon and alloy steels, stainless steels, ASTM petrochemical bolting grades, Duplex, Super Duplex, nickel alloys, titanium, non-ferrous materials and project-specific specifications.
SNB supports material-led fastener and component requirements with traceability, testing and certification aligned to the customer and project specification.
Why Material Knowledge Matters
Fastener and component performance can be affected by material strength, corrosion resistance, temperature, heat treatment, coating compatibility, testing requirements and the applicable specification. SNB reviews the material requirement and the supporting documentation before supply so the correct commercial and technical route can be defined.

Carbon & Alloy Steels
Applications: General industrial bolting, structural applications, flanged connections, pressure systems and high-temperature bolting.
Stainless Steels
Applications: Corrosion-resistant fasteners, marine environments, food and process industries, pump and valve applications.
17-4PH conditions can include Condition A, H900 and H1025 subject to specification.
ASTM / Petrochemical Bolting Grades
Applications: Flanged pressure connections, high- and low-temperature bolting, refinery, process and energy applications.
Duplex & Super Duplex
Applications: Offshore, subsea, marine, chemical processing and seawater systems requiring high strength and corrosion resistance.
Nickel Alloys & High-Performance Alloys
Applications: Aggressive corrosion environments, sour service, high-temperature service, subsea, aerospace, chemical and nuclear-related supply chains.
Non-Ferrous Alloys
Applications: Lightweight structures, electrical components, marine applications and specialist engineering requirements.
Titanium & Specialty Engineering Alloys
Applications: Aerospace, subsea, high-performance engineering, weight-critical applications and anti-galling requirements.
Certification, Testing & Traceability for Material Supply

Customer-specific material requirements reviewed at enquiry
Need Help Interpreting a Material Requirement?
SNB can review drawing requirements, specification references, commercially available grades, documentation requirements and potential equivalent material routes. Final material selection and application suitability remain subject to the customer's engineering or design authority.
