Properties |
It has high strength and good alkali resistance,and was considered as an ideal alternative to -13NL,and has longer campaign life. |
After service,the surface was smooth and no crack is existed;it has better high temperature resistance. |
|||
Refractory steel fiber can be added as request and "teel fiber reinforced" should be added in front of the product name and an "F" shall be added behind the brand .The brand should be JC-M45F??JC-M60F??JC-M65F and JC-M70F. | |||||
