MNK Technical Library
Technical Guides for Industrial Material Sourcing
Practical guidance for defining grades, reading manufacturing ranges, preparing technical inquiries and reviewing the documents that control an industrial supply.


Technical sourcing connects dimensional verification, documentation and packaging requirements in one controlled supply route.
Sourcing Decisions Explained Step by Step
These guides explain the controls used before quotation. They do not reproduce protected standards and do not turn a commercial designation, a global size range or a previous supply into an automatic guarantee for a new order.
Grade Control
ВК, WCo and YG Hardmetal Grades
How MNK separates designations, composition, microstructure, application classifications and certificate evidence before treating two hardmetal references as related.
Read the grade-verification guide →
Use the Cemented Carbide Inspection and Test Methods guide to define sampling, compatible test methods, acceptance limits and traceable reporting for a hardmetal inquiry.
Dimensional Control
Tungsten and Molybdenum Size Ranges
How to read a global sourcing envelope without assuming that its minimum thickness, maximum width, maximum diameter and longest length form one available product.
Inquiry Control
Industrial Metals RFQ Checklist
A practical checklist for material, standard, product form, dimensions, tolerances, quantity, drawing, inspection documents and delivery information.
Standards Access
Standards and Documentation
Use the Technical Library to find MNK scope guides, official publication records and the document-access policy for protected standards.
Reference Control
Material Grade Cross-Reference
How MNK distinguishes a direct standard designation, closest equivalent, application-group correspondence, commercial variant and a case with no identified direct equivalent.
Product Standard Control
Material Standards by Product Form
Why plate, bar, wire, tube, pipe, forgings, fasteners and parts to drawing may require different material and product standards.
How to Use the Guides
- Start with the guide that matches the uncertainty: grade, dimensions, documents or RFQ completeness.
- Use the linked product and standards pages to identify the relevant material family and governing publication.
- Send the complete requirement, drawing and document expectations through the MNK inquiry form.
- MNK checks the request against suitable manufacturing sources and returns the points that require confirmation.
Guide Boundaries
MNK technical guides support inquiry preparation and procurement review. They do not replace the authorised standard, customer specification, approved drawing, qualified procedure or project engineer’s decision. Current availability, certification and manufacturing feasibility are confirmed for each inquiry.
