Cold rolled stainless steel strips W.-Nr. 1.4031 ( DIN X39Cr13 )

Designation by standards

Description

Martensitic grade with medium-high hardness. Corrosion resistant in water and steam.

Applied for cutting utensils, surgical instruments, measuring tools, mechanical parts subject to wear.

W.-Nr. 1.4031 ( Din X39Cr13 ) is used in the quenched and tempered condition in a host of constructional applications where moderate corrosion and abrasion resistance is required.

Due to its higher carbon content, DIN 1.4031 is more hardenable than W.Nr. 1.4028 and as such is suitable for use as

a blade material.  As for other martensitic grades, optimal corrosion resistance is attained when the steel is in the

hardened condition and the surface is finely ground or polished.

Chemical composition ( in weight % )

Applications

* blades for knives and various food preparation utensils
* blades for industrial equipment

* cutting tools
* mechanical parts and miscellaneous tools etc.

* The stainless steels used for cutlery belong to the martensitic steel family. 

They contain mostly carbon and chromium. However, other alloy elements may be included like molybdenum and vanadium.
