The alloying elements in the A213 T91 steel have solid solution strengthening, which can guarantee the steel oxidation resistance and corrosion resistance.
A213 T91 alloy steel pipe Application:
Widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, car drive shaft, bicycle frame and construction scissors and so on.
The final heat treatment of A213 T91 alloy steel is normalizing + tempering: Normalizing temperature of 1040 ℃, holding time of not less than 10 min; Tempering temperature of 730 ~ 780 ℃, holding time of not less than 1h. After the final heat treatment, the organization of T91 alloy steel is tempered martensite.
