We introduce some common questions or inquiries from customers.

Why stainless steel is sometimes attracted by magnet?


There are three types of stainless steel.
(Austenitic type, Ferritic type, Martensitic type)
Basically, SUS304 (Austenitic) is not magnetic, but SUS430 (ferritic), SUS410 (martensite) is magnetic.
Work hardening and processing-induced martensitic transformation occurs by cold heading or rolling process, increased permeability, can be attracted to magnet even if it is SUS304.

※What is the processing-induced martensitic transformation?
Transformation of austenite by processing and be a two-layer structure including martensite.

What is the difference between Neospo and Reston for packing material?


Both of Neospo and Reston are made of CR, but processing method is different.The plate of Neospo(thickness × 1000 × 1000 (Unit: mm)) is cut width,so it become a spongy surface and 1m units will be strung together.Reston attaches to the surface film and a sponge rubber extrusion.(Length:1m〜100m)Can be used without any stitching.

What does Trivalent mean?


There are two ways to represent the interpretation of Trivalent Chrome and trivalent chromate.
Trivalent Chrome is a generic term of material which is included +3 in the oxidation number of chromium compounds.
The trivalent chrome compounds are commonly used chromium nitrate and chromium sulfate.
Trivalent Chromate is the plating process which is a way to use the process liquid consisting of a trivalent chrome compound on the electrical galvanized chemical film.

※Difference of trivalent and hexavalent chromate is the process liquid of conversion coating process.
