Stainless steel
Stainless steel is a family of corrosion-resistant, high-alloy steels defined by a minimum chromium content of approximately 10.5%, which forms a passive oxide layer (Cr2O3) that protects against oxidation and chemical attack. This inherent durability, combined with strength, ductility, and ease of fabrication, makes it indispensable across industrial, architectural, and consumer applications. Konsond concentrates more on Martensitic grades (High-carbon high-chromium) with outstanding hardness and wear resistance. Key grades includes 1.4016, 1.4034,1.4112,1.2361,1.4125,430,440B,440C and duplex grades -balance strength and corrosion performance for harsh environments.
