SUS (stainless steel) material test piece/specimen

This page introduces test pieces and specimens made of SUS (various types of stainless steel) materials that can be manufactured at TDC.

TDC’s SUS material test piece/specimen

At TDC, we accept orders from manufacturing to processing of test pieces and specimens using various SUS (stainless steel) materials.

In production, it is possible to respond from cutting processing. With our special polishing and grinding technology, we are able to produce a variety of test pieces, from mirror surfaces with a surface roughness of Ra1nm to pear-skin (frosted glass).

Examples of SUS materials that can be used to manufacture and process test pieces and specimens

Below are some examples of SUS materials that we receive requests for.

Material	Feature
SUS301	A material with less nickel and chromium than SUS304 and a higher carbon content. The material strength is high, and the strength is higher than other stainless steel materials.
SUS303	It has the characteristics of being easy to shave and easy to machine because the chips are clean.
SUS304	Compared to other stainless steels, it has excellent cold workability and weldability, making it easy to bend and weld.
SUS310	Among stainless steels, it has excellent acid resistance and is often used as a heat-resistant steel.
SUS316	It has excellent corrosion resistance in various media and is also suitable for marine environments.
SUS321	Stainless steel based on SUS304 with titanium added to improve the corrosion resistance of welds. It is also characterized by high temperature strength.
SUS403	It has excellent corrosion resistance and toughness after heat treatment, and can be hardened by quenching and tempering. Suitable for applications that require heat resistance and high strength.
SUS410	Stainless steel with corrosion resistance after heat treatment and high machinability. Corrosion resistance is inferior to other stainless steel materials, but hardness can be strengthened by quenching.
SUS420J2	One of the characteristics is that it has a high carbon content and has properties that are very close to those of iron. Although it has the disadvantage of being prone to rusting, high strength and high hardness can be obtained by heat treatment such as quenching and tempering.
