431 stainless steel is a high-chromium, low-nickel, high-hardenability martensitic stainless steel with high strength and good corrosion resistance, usually hardened in the tensile range 850-1000 MPa (condition T) Brinell range 248-302 and Tempering.
444 stainless steel is a high-alloy ferritic stainless steel. Compared with the commonly used steel SUS430: 1. The chromium content is about 1.0% higher, and the alloying element molybdenum (Mo) is added, so this steel has good resistance to pitting corrosion and cracks. Corrosion and stress corrosion resistance, its corrosion resistance is even better than SUS304 and SUS316 in some areas. 2. Titanium (Ti), niobium (Nb), zirconium (Zr) and other stabilizing elements are added, so this steel type has good Excellent resistance to intergranular corrosion and high temperature oxidation.
