434 ferritic stainless steel. Contains 12% to 30% chromium. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its chloride stress corrosion resistance is better than other types of stainless steel. 434 (18Cr-1Mo) is an improved steel type of 430 steel. It is more salt-resistant than 430 steel and is used as automotive exterior decorative materials. Corresponds to the national standard 1Cr17Mo and the Japanese standard SUS434.
416 Stainless Steel Stainless steel 416 is an American standard ASTM executive standard steel grade. It is an easy-cutting stainless steel with better performance. This steel has an increased sulfur (S) content of more than 0.15%, making the material easy to turn. It is a martensitic steel. The solid stainless steel can enhance its performance through heat treatment. Its strength and machinability are better than those of 304 and 316, and its friction coefficient is small.
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.
