25th floor, C3 Building, Wanda Plaza, Kaifu District, Changsha, Hunan Province, China.What is 1.4418 martensitic chromium nickel molybdenum stainless steel? RONSCO introduces you to the composition standard and heat treatment performance of 1.4418 stainless steel.
1.4418 is a good martensitic grade stainless steel, with sufficient corrosion resistance, good strength performance and high hardness, and the carbon content is reduced.
1.4418 stainless steel has good strength and corrosion resistance of welded joints, fatigue resistance, very good parameters in low temperature environments, and corrosion resistance is equivalent to austenitic steel 18-8. In addition, it has good weldability.
1.4418 stainless steel can be used when working at low concentrations at room temperature, usually in contact with acetic acid, citric acid, salt solutions, pyrogallic acid, tannins, stearic acid and some nitrate and sulfur compounds.
1.4418 stainless steel mainly provided in the form of rods are used to produce valves, turbine components, nuts and bolts, shafts, pins, pistons, main shafts, crankshafts, agitators, and are used in chemical, energy, marine, shipbuilding, aviation/cryogenic industries.
