ASK Brand
Products with Pb-free, high hardness, high corrosion resistance, and high machinability are available.
Pb-free
Development of Pb-free steel that complies with environmental regulations such as RoHS.
It maintains machinability equivalent to steel containing Pb, making it easy to switch from the currently used steel.
We have a Pb-free lineup based on JIS standard SK, SUM, SUS, and can manufacture products with an outside diameter of 1.00 mm to 27.00 mm.
