Nippon Steel develops corrosion-resistant welding material
Nippon Steel develops corrosion-resistant welding material
Keywords: Materials, Welding, Corrosion resistance
Nippon Steel Corp. has developed a welding material that resists corrosion even when it comes in contact with hydrochloric acid and sulfuric acid.
The new material was made by mixing alloy elements such as copper and antimony with common steel materials. Its rate of corrosion has been reduced to one-fortieth that of regular steel when in contact with hydrochloric acid.
It comes in both rod and wire forms, and can be used in the same way as conventional welding materials.
Nippon Steel subsidiary Nippon Steel and Sumikin Welding Co. will manufacture and sell the material, which is expected to find application in chemical plants, waste incinerators and similar facilities that require maintenance because of deterioration in welds.
Last year, Nippon Steel released a steel plate with the same corrosion resistance as the new welding material. By selling the new material with this steel, the aim is to sell 5,800 tons of steel this fiscal year.
