Hygienic Fabrication from a Single Source

Stainless steel components for the food industry must be impeccably hygienic – from the weld seam to the surface finish. At Numberger Technologies, stainless steel is processed in areas strictly separated from mild steel: dedicated zones, dedicated tooling, no steel particles contaminating the stainless steel.

TIG welded, purged and full-penetration. Pore-free, gap-free weld seams without heat tint. Burr-free edges, no dead zones. Surface roughness Ra < 0.8 – ground, polished or electropolished.

All standard grades from stock: 1.4301, 1.4404, 1.4571 and further grades on request. Material inspection certificates 3.1 to EN 10204 as standard. Full batch traceability.

Frequently Asked Questions

Which stainless steel grades are food-safe?
For food contact applications, 1.4301 (V2A) and 1.4404 (V4A / 316L) are the standard grades. 1.4404 offers better corrosion resistance due to its molybdenum content and is preferred where aggressive cleaning agents are used.
What is the difference between 1.4301 and 1.4404 for food applications?
1.4301 (V2A) is the more cost-effective standard stainless steel. 1.4404 (316L) contains molybdenum for higher resistance to chlorides and acids. For food contact with aggressive media – CIP chemicals, salt brines, acidic products – 1.4404 is the safe choice.
What surface finish is required for food contact stainless steel?
Ra 0.8 is the typical requirement for food contact surfaces. We grind and polish to these values. Electropolishing is available and produces even smoother, easier-to-clean surfaces. Roughness is measured directly on the component using our in-house surface profilometer – measurement report included.
How must stainless steel be welded for food industry use?
Purged and full-penetration using the TIG welding process. Purge gas protects the weld root from oxidation. The result: pore-free, gap-free seams without heat tint – no crevices where biofilm can form.
Can you supply material test certificates?
Yes – material inspection certificates 3.1 to EN 10204 are standard. Every material is traceable back to the melt heat number.
Do you supply to food machinery builders outside Germany?
Yes – we supply food industry customers and machinery builders throughout Europe. All documentation can be provided in English. Contact us with your drawing or specification for a quote within 48 hours.
