"ONLY-1" Brand

ASK made the some characteristic steels from the technical skills and research in the many years.
The new valuable precision parts requested from the market is made from our original Brand.

metallographic structure

ASK-8000

ASK-8000 is made of stainless steel which has a high strength material at the bar materials,
also have high corrosion resistance.You can omit the quenching and Ni-plating, etc.
After the machining process, you can reduce the total production cost, including the lead time.

Catalog and Chemical composition

ASK-3000T

Free-cutting stainless steel made using SUS 304 as the base steel, incresing its sulfur content and adding tellurium,
therefore Its machinability is drastically become excellent .

Catalog and Chemical composition

ASK-3000S

Free-cutting stainless steel made using SUS 303 as the base steel, incresing its sulfur content.
Therefore Its machinability become excellent .

Catalog and Chemical composition

ASK-3000FL

Free-cutting stainless steel made using SUS 303 as the base steel, incresing its sulfur content and adding lead.
Therefore the machibnability level of ASK-3000FL is the highest steel in Austenitec stainless steel.

Catalog and Chemical composition

ASK-3200

Free-cutting stainless steel made using SUS 430 as the base steel, incresing its corrosion resistance with the composition
of 20Cr-2Mo and adding lead and tellurium, therefore Its machinability become excellent .

Catalog and Chemical composition

ASK-3300T

Free-cutting stainless steel made using SUS 430 as the base steel, incresing its sulfer and adding lead and tellurium.
The machibnability level of ASK-3300T is the highest steel in Free-cutting stainless steel.

Catalog and Chemical composition

ASK-3500A

Free-cutting stainless steel made using SUS 410 as the base steel, addinging its sulfer, lead and tellurium.
Therefore Its machinability become excellent .

Catalog and Chemical composition

ASK-3400T

Free-cutting stainless steel made using SUS 420J2 as the base steel, addinging its sulfer, lead and tellurium.
Therefore Its machinability become improved without the impaired hardenability .

Catalog and Chemical composition

ASK-2600

Super free cutting steel made using SUM24L as the base steel, increasing its lead content.
Its machinability is suitable for the heavy cutting process.

Catalog and Chemical composition

ASK-2600S

Ultra-super free cutting steel made using SUM24L as the base steel, increasing its lead content and adding tellurium,
Therefore Its machinability is increased than ASK-2600.

Catalog and Chemical composition

ASK-2800

ASK-2800 made using SUM24L as the base steel, increasing its lead content and adding tellurium and bismuth,
The machibnability of ASK-2800 is the highest steel in Free-cutting steel.
