Note: 1. FeNb60-B, FeNb20 two brand is niobium iron concentrate as raw material to produce.
2. Niobium to block supply iron. The most massive niobium iron large he***y not more than 8 kg, less than 20 MM × 20 MM of fragments weight must not exceed total quality of 5%.
In the metallurgical industry in alloy agent to join as a niobium, heat resistant steel in stainless steel and add niobium, to improve the plasticity and resistance to corrosion, structural steel if niobium, can improve the welding pe***nce. And improve strength and plasticity, and prevent weld corrosion. For high temperature steel and high temperature alloy for, niobium is indispensable, because niobium can improve the high temperature strength, fine grains, prevent heat grain growth. Niobium and carbon combined into carbide, which can eliminate the carbonization chromium deposition in the stainless steel to the harmful action to improve the corrosion resistance. - 觉得产品介绍不够清楚？欢迎你提问，第一时间解答您的疑惑 点此留言
