Material Overview

17-4PH Stainless Steel for Project-Specified Fasteners

17-4PH stainless steel is a precipitation hardening stainless steel material commonly discussed for project-specific industrial fasteners and custom parts where the material is specified by project documents.

17-4PH can be considered for bolts, stud bolts, threaded rods, nuts, washers, special fasteners and drawing-based components when project requirements call for this material. Final material selection should be reviewed according to service conditions, mechanical requirement, heat treatment condition, applicable standard and project specification.

Procurement Focus

  • Confirm 17-4PH, Type 630, UNS S17400 or 1.4542 designation
  • Confirm heat treatment or material condition where required
  • Confirm product type, dimensions, thread and quantity
  • Confirm certificate and inspection requirements before quotation
  • Confirm application environment if material review is needed
Equivalent Grades

Common 17-4PH Designations for RFQ Review

These names are commonly referenced in procurement documents, but equivalent designations, heat treatment condition and applicable standards should be confirmed according to order requirements, product form and project specification.

Name / Designation Common Reference Notes for Quotation Confirmation
17-4PH stainless steel 17-4 precipitation hardening stainless steel Confirm material condition, heat treatment requirement, product form and applicable standard before quotation.
Type 630 stainless steel 630 stainless steel Often referenced for stainless steel fasteners and machined parts; final specification should be confirmed before production.
UNS S17400 UNS designation Confirm the applicable standard and certificate requirement according to project documents.
EN / DIN 1.4542 European material reference Equivalent designations should be confirmed according to order requirements and project specification.
Equivalent designations, heat treatment condition and applicable standards should be confirmed according to order requirements, product form and project specification.

Selection Notes

Material Comparison Notes During RFQ Preparation

Customers may compare 17-4PH with 316L stainless steel, A286, XM-19, Inconel 718, Duplex 2205, Super Duplex 2507 and 15-5PH during RFQ preparation. These materials should not be treated as automatic replacements for one another.

Final material selection should be reviewed according to service environment, mechanical requirement, heat treatment condition, standard and project specification. 17-4PH and 316L should not be treated as interchangeable without project confirmation.

Selection Questions to Confirm

  • Which material designation and standard are specified?
  • Is heat treatment or material condition required?
  • Is the part a standard fastener or drawing-based component?
  • What certificate and inspection documents are required?
  • Is the application environment relevant to material review?
Documents

Standards, Certificates and Inspection Documents

Document requirements should be discussed before quotation. Certificate availability should be confirmed before quotation and should not be assumed for every 17-4PH product.

Material Certificates

Material certificates can be discussed when required. EN 10204 3.1 / 3.2 documents can be discussed according to order requirements, product form and supply conditions.

Heat Treatment and Material Condition

Heat treatment condition or material condition should be confirmed according to project specification where required. Final specification should be confirmed before production.

Inspection Requirements

PMI, third-party inspection, coating report or inspection documents should be confirmed before quotation when required.

Order-Specific Requirements

NACE / MR0175 or project-specific corrosion-service requirements should be confirmed as order-specific requirements and not assumed.

WISINE does not treat 17-4PH products as automatically approved for aerospace, nuclear, medical, military, structural, pressure or corrosion-service applications. Project requirements should be confirmed before quotation.

FAQ

17-4PH Stainless Steel Fasteners FAQ

Can WISINE quote 17-4PH bolts and stud bolts?

17-4PH bolts, stud bolts and threaded rods can be discussed according to project requirements, material availability, quantity, processing requirements and document requirements.

Is 17-4PH the same as Type 630?

17-4PH and Type 630 are commonly referenced together, but equivalent designations, heat treatment condition and applicable standards should be confirmed according to order requirements.

Should heat treatment condition be included in the RFQ?

Yes. Heat treatment or material condition should be confirmed according to project specification where required, especially for drawing-based parts and project-specific fasteners.

Are certificates automatically included?
