★ Monel 400, K-500
Monel 400 is in a large amount, versatile, good performance, high corrosion resistance of nickel-copper alloy. Chemical composition mainly by about Cu30% and Ni65%, plus a small amount of Fe (1-2%) of the composition, also known as MCu-28-1.5-1.8. Organizational structure for single-phase austenite.
Monel corrosion tolerance generally superior to copper than nickel, it is more resistant than pure nickel reducing corrosion medium, oxidation resistance than pure copper corrosion medium sulfuric acid, phosphoric acid, carbon is a very good corrosion resistance, in particular, hydrochloric acid corrosion resistance of the hot concentrated alkali is also excellent in corrosion resistance. |
