Iron, Steel & Alloy Sourcing for Industrial Buyers
Source carbon, stainless and alloy steel in sheet, coil, bar or billet. Share grade, chemical composition, dimensions, tolerances and tonnage in an RFQ.
Iron, Steel & Alloys sourcing guide
Global B2B Sourcing of Iron, Carbon Steel & Special Alloys
Heavy industries, automotive manufacturing, energy production, and mechanical engineering rely on specific metallurgical grades, high-purity raw metals, and high-performance alloy formulations. BIGEXPORT helps connect industrial buyers with steel mills and metallurgy foundries worldwide.
Buyers can submit Requests for Quotations (RFQs) for pig iron, hot-rolled steel coils, stainless steel plates, tool steels, nickel alloys, and custom forgings.

Sourcing Metals & Alloys on BIGEXPORT
When submitting a request, buyers should detail their technical requirements to receive relevant quotes. Key specifications to include in your RFQ are:
Compliance with relevant global standards (ASTM, EN, DIN, JIS, ISO 9001, AS9100).
Full traceability documentation, such as EN 10204 3.1 / 3.2 Mill Test Certificates (MTC).
Needs for custom services, including vacuum induction melting (VIM), electroslag remelting (ESR), precision forging, and heat treatment.
Frequently Asked Questions (FAQ)
Are Mill Test Certificates (MTC) supplied with raw steel and alloy shipments?
Buyers should specify the need for Mill Test Certificates (MTC) in their RFQ. Many suppliers can provide comprehensive MTCs detailing chemical composition, tensile strength, yield strength, and impact testing according to standards like EN 10204 3.1/3.2.
What is the difference between duplex stainless steel and standard austenitic stainless steel?
Duplex stainless steels possess a dual-phase microstructure (ferrite and austenite) providing nearly double the yield strength and superior stress corrosion cracking resistance compared to standard 300-series stainless steels.
Can I source custom-forged shapes and heat-treated alloy billets?
Yes. In your RFQ, you can detail your requirements for custom open-die/closed-die forging, precision machining, and specialized heat treatments like annealing, quenching, and tempering. BIGEXPORT will match your request with suppliers that have suitable capabilities.
