STEEL
With the increase in business volume and control our raw material cost, we invested to build our own steel factory in 2005. We have advanced international steel production equipment, including ultra high power electric furnace, different tonnages electroslag furnace, vacuum induction furnace, consumable electrode vacuum furnace, high-speed forging hydraulic press and etc. We can produce steel with applicable standards (AISI, DIN, JIS, ISO, GB), even custom requirements from customers. With years experience, our steel factory branch manufacture and supply tool steel, alloy steel, carbon steel, and stainless steel for round bar and sheet with wide range of dimension, also we can hardening and tempering with customers’ requirements. They widely be used in shipbuilding, engineering machinery and etc.
