Common DIN 2093 A, B and C group sizes are listed for buyer RFQ screening. A group follows catalog page 13, B group page 14, and C group / GB 1972 reference page 15. Final load, fatigue and material choice should be confirmed against the application.

Available Material Families

Standard spring steels	60SiCr7 / 51CrV4 / 9260H / 6150	-50 to +177 deg C	0.3-30 mm	1400-2000 MPa
Corrosion resistant stainless	301 / 304 / 316 / 17-7PH	-240 to +355 deg C	0.2-50 mm	950-1800 MPa
Heat-stable steels	1.4923 / H13 / X39CrMo17-1	-50 to +600 deg C	1.5-50 mm	1100-1740 MPa

DIN 2093 sourcing notes for buyers

DIN 2093, DIN 2093 B, DIN 2093 disc spring manufacturer and DIN 2093 Belleville washer supplier requests usually need more than a standard size reference. The practical decision is whether the washer must hold a repeatable load window in a valve, bolted joint, actuator, transmission or heavy equipment assembly.

For faster review, combine the DIN 2093 size or drawing with target load, working deflection, stack arrangement, temperature, corrosion media and whether the part is for sampling, maintenance replacement or repeat production.

For sourcing discussions around DIN 2093 disc springs, DIN 2093 Belleville washers or disc spring RFQs, buyers usually get a faster answer with a quote-ready specification: size range, load class, material options, quantity and the risk the spring must control.

If the inquiry is only "disc spring RFQ", "DIN 2093 RFQ" or "DIN2093 disc spring manufacturer", FeTech can begin from a standard DIN size, existing sample, drawing or target load table, then confirm whether a catalog spring or custom stack is the better purchasing route.

This section is for buyers who need a manufacturer, catalog-size replacement or quote-ready Belleville washer source rather than a general standard definition. If the project is in the United States or Europe, include drawing revision, sample status, annual quantity and certificate needs so FeTech can separate prototype review from repeat purchasing.

Common Product Questions

When should I choose standard DIN 2093 disc springs?

They are usually the best starting point when you need standardized dimensions, predictable stack behavior and easier replacement across industrial programs.

Can DIN 2093 disc springs also be supplied in stainless or Inconel?

Yes. Many projects keep DIN 2093 geometry but upgrade the material when corrosion, heat or preload-retention requirements go beyond ordinary spring steel.

What information helps FeTech quote DIN 2093 disc springs faster?

Send the DIN 2093 size or OD, ID, thickness, load class, material, quantity, target load, working deflection, stack arrangement and whether the parts are for replacement, samples or repeat purchasing.

Can FeTech support DIN 2093 replacement sourcing for maintenance buyers?

Yes. For MRO and replacement projects, FeTech can review the existing washer size, stack arrangement, material, operating temperature and failure problem before quoting equivalent or upgraded disc springs.
