DIN EN 10088-2:2025-01

Technical delivery conditions for sheet and strip of stainless steels

DIN EN 10088-2 specifies the technical delivery conditions for hot- and cold-rolled sheet and strip of corrosion-resistant stainless steels. It describes requirements for material properties, delivery conditions, testing and marking and supports the selection of suitable stainless steels for general applications in industry and construction. The standard supplements the material overview in EN 10088-1 with specific delivery and quality requirements.

What is DIN EN 10088-2 about?

The standard defines the technical requirements for flat products made of stainless steels, including chemical composition, mechanical properties, surface finish, dimensional tolerances and test methods. It applies to hot- and cold-rolled sheet and strip of corrosion-resistant steels for general purposes, including applications involving food contact. In addition, it describes delivery conditions, inspection documents and marking requirements, providing an important basis for clear material selection and international comparison of stainless and corrosion-resistant steels.

Topics covered

• Technical delivery conditions for sheet and strip of stainless steels
• Chemical composition of different steel grades
• Austenitic, ferritic, martensitic, duplex and precipitation-hardening steels
• Mechanical properties at room temperature and elevated temperatures
• Surface finishes and delivery conditions
• Test methods, inspection documents and proof of conformity
• Dimensional, form and tolerance requirements
• Marking of flat products
• Information on hot forming and heat treatment

Practical relevance

Stainless steels are used in numerous sectors, including mechanical engineering, plant engineering, energy technology, the chemical industry, food technology and construction. DIN EN 10088-2 supports clear material selection and facilitates comparison between different steel grades. It therefore provides an important basis for design, material specification, procurement and quality assurance.

The information on material numbers, chemical compositions, mechanical properties and fields of application is particularly relevant. This helps users select suitable stainless and corrosion-resistant steels for corrosive, thermally stressed or highly demanding operating conditions.
