A European steel service centre handling 47 active grade specifications across five international standards bodies — ASTM, EN, JIS, API, and ISO — was managing its entire grade library in a combination of spreadsheet files and a shared drive folder structure that had accumulated nine years of partial updates, duplicated entries, and superseded specification versions. When a customer complaint arose over a structural grade supplied to a bridge project, the investigation revealed that the grade specification used for the internal compliance check had been superseded two years earlier and the updated version was in the shared drive but had never been flagged or linked to the production records. The non-conformance was not a production failure. It was a specification management failure — one that an organised, version-controlled digital grade library would have prevented automatically. Sign in to OxMaint to build a digital grade library that tracks every specification version, links every heat record to its applicable grade, and generates compliance evidence automatically. Book a demo to see OxMaint's grade library, certification tracking, and material traceability platform in action.
A steel grade library is not a spreadsheet problem. It is a version control problem, a heat traceability problem, and a compliance evidence problem — all requiring a single connected system.
From ASTM A36 to EN 10025 S355, from API 5L Grade B to JIS G3101 SS400 — every grade your mill produces carries a specification, a compliance obligation, a certification requirement, and a heat record. OxMaint connects all four into a single grade management system that keeps every specification current and every heat traceable.
Steel grade library management spans four interconnected domains. Each domain has distinct data requirements, update cycles, and compliance obligations. OxMaint manages all four from a single platform — linking every grade specification to the heat records, certifications, and customer orders it governs. Sign in to OxMaint to configure all four grade library domains for your plant's active grade portfolio.
The complete chemical composition, mechanical property, dimensional tolerance, and surface condition requirements for every steel grade your plant produces — organised by standard body, version-controlled, and linked to the heats and orders that consume them.
Grade equivalency mapping across ASTM, EN/ISO, JIS, API, BS, DIN, and customer proprietary specifications — enabling service centres to identify substitution grades, confirm inter-standard equivalencies, and communicate grade relationships to customers purchasing to different national standards.
Every heat or charge number linked to its grade specification version, chemical analysis result, mechanical test data, casting record, and downstream processing history — maintaining the unbroken material identity chain that customer audits, third-party inspections, and regulatory investigations require.
Mill test certificates, certificates of conformance, certificates of analysis, and third-party inspection reports — generated automatically from the heat record and grade specification database, linked to the customer order, and stored in a searchable compliance archive accessible for audit preparation at any time.
OxMaint's Grade Library delivers operational value from the first grade loaded. The five implementation milestones below build progressively — each one unlocking additional compliance and traceability capabilities. Most steel plants reach full implementation within 4–6 weeks.

Steel shipments require different certification types depending on the customer's industry, application, and contractual requirements. OxMaint generates all three primary certificate types automatically from the heat record and grade specification database — with customer-specific formatting where required. Book a demo to see certificate generation for your customer types.
When an international standard is revised — EN 10025 updated, ASTM A572 amendment issued, API 5L specification change — OxMaint creates a new version of the affected grade specification while preserving the previous version in archive. Every heat produced while the old version was current remains linked to that version permanently. Every heat produced after the update uses the new version. This automatic version-to-heat linkage means that even years after an amendment, you can demonstrate which specification was in force for any specific heat — a requirement that arises in product liability investigations, lease return audits, and third-party quality challenges. Sign in to OxMaint to activate version-controlled specification management for your grade library.
OxMaint maintains the complete material traceability chain from the heat number that entered the converter through every downstream process — casting, rolling, slitting, cutting, coating — to the customer order and dispatch record. For service centres handling purchased slab or semi-finished material, the incoming MTC data from the primary producer is linked to the internal processing record and outgoing certificate. When a customer or third-party auditor requests the full material history for a delivered product, OxMaint generates the complete chain in a single package rather than requiring manual assembly from multiple source systems. Book a demo to see full-chain heat traceability in OxMaint.
When a spectrometer result is entered or imported for a heat, OxMaint automatically checks every element against the applicable grade specification version — flagging exceedances, borderline results, and elements approaching limits. Mechanical test results are checked against the grade's property requirements when received from the testing laboratory. Compliance status — fully conforming, conditionally conforming with metallurgist approval, or non-conforming — is assigned automatically and recorded in the heat record, with the specific exceedance detail retained for any subsequent investigation. Sign in to OxMaint to configure automated compliance checking for your grade portfolio.
When a customer requests a full quality audit package — all MTCs, COCs, test reports, and inspection certificates for deliveries in a specified date range or against a specific order number — OxMaint generates the structured package in the format the customer specifies, directly from the grade library and heat record database. Packages that previously required a quality administrator to spend 2–3 days retrieving and assembling documents from multiple systems are generated in under 15 minutes. For IATF 16949 supplier audits, EN 10204 certification audits, and project supply documentation requirements, the package is complete, version-accurate, and heat-traceable. Book a demo to see audit package generation from OxMaint's grade library system.
We were handling 52 active grade specifications across ASTM, EN, and API standards, plus 11 customer proprietary grades from our three largest automotive accounts. The specification management was in a shared drive that nobody had properly maintained since 2019. When we had a customer audit for our Tier 1 automotive supply approval, we discovered that two of our internal specification documents had been updated in the shared drive but the production system was still referencing the old versions for compliance checking. We passed the audit on appeal — but it cost us three weeks and significant commercial risk. After implementing OxMaint's grade library, every specification is version-controlled, every heat links to the correct version automatically, and our last two customer audits generated zero specification management findings.
