Cold Heading Quality (CHQ) wire is produced through drawing or annealing the raw material. Our customers use our product to manufacture fastening components like bolts, nuts, screws, and mechanical parts for the automotive, electronics, and construction industries.
High-quality cold-worked products produced in cutting-edge facilities
SeAH Special Steel produce excellent quality CHQ wire with high durability and precision using cutting-edge facilities, such as a hydrogen bell-type furnace and an automatic pickling line, and supply it to global markets.
Establishment of a supply chain to differentiate manufacturing competitiveness
SeAH Special Steel has the largest manufacturing capacity in the CHQ wire market and distinguishes itself through strict supply chain management to meet delivery deadlines.
Specialized coating processes for superior surface quality
SeAH Special Steel Secure a portfolio of specialized coatings, such as non-phosphating and oil-cleaning coatings, and achieve aesthetically pleasing and superior surface quality to meet a wide range of customer needs.
Hydrogen bell-type furnace heat treated products
Our heat treated products exhibit dramatically improved quality, including spheroidized texture, mechanical properties, and uniform coating. These products excel in cold forming, extend mold life, and enhance the heat treatment of the notoriously difficult-to-heat-treat SWCH45F bearing steel.
Seam-free wire products
Seam-free wire product prevents surface defects that may occur in the raw material. Once produced, it is shaved to a specific depth with a shaving machine to remove any defects that may occur during cold forming. It is a strategic product designed to meet demanding and stringent quality standards.
