Other alloying elements on CA6NM

Adding micro-alloy elements Ti, Nb, and V in a martensitic stainless steel tube is usually expected to form a nitrogen compound with C and N. As a result, increasing the strength of the steel. Ti is a stabilizing element. 

At the same time, it is a fine crystalline element. Ti can form a variety of stable carbon-nitrogen compounds. Finally, Ti (C, N) can increase the toughness without sacrificing strength. The addition of 0.1% Nb in CA6NM martensitic stainless steel can reduce the precipitation of the rich Cr ions. Because Nb can combine with C and N atoms to form nanometer-grade Nb-rich precipitates (5-15nm). The homogeneous distribution of rich Nb precipitates can increase the strength of the steel and hence optimize its plasticity and toughness.

The addition of microalloying elements Ti, Nb, and V to martensitic stainless steel pipes is generally expected to form nitrogen compounds with C and N, thereby increasing the strength of the steel. Ti is a stable element.

At the same time, it is a fine crystalline element. Ti can form a variety of stable carbon and nitrogen compounds. Finally, Ti(C, N) can increase toughness without sacrificing strength. Adding 0.1% Nb to CA6NM martensitic stainless steel can reduce the precipitation of Cr-rich ions. Because Nb can combine with C and N atoms to form nanoscale Nb-rich precipitates (5-15nm). The uniform distribution of Nb-rich precipitates increases the strength of the steel, thereby optimizing its ductility and toughness.
We are very good at producing CA6NM centrifugal casting tubes!
