Z6CA13、Z8CA12、F.3111-X6CrAl13

characteristic

Ferritic stainless steel. Contains 12% to 30% of chromium. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and the resistance to chloride stress corrosion resistance is better than other types of stainless steel.

use

Such as steam turbine blades, structural frames, stainless equipment, linings, bolts, nuts, etc.
