What is 1.4418, X4CrNiMo16-5-1 grade steel?
1.4418 has higher tensile properties, excellent ductility and better corrosion resistance than ordinary 400 series martensitic materials, very good corrosion resistance in corrosive media and very good mechanical and impact properties, At the same time reduced carbon content, good corrosion resistance and low temperature toughness up to -200°C In the quenched and tempered state, the structure of X4CrNiMo16-5-1 consists of tempered martensite + stabilized austenite and a small amount of ferrite . The number and distribution of these phases is strictly dependent on the chemical equilibrium. In the quenched state, higher Rm and HB values are obtained, reaching a maximum after tempering at about 450°C. Raising the temperature above 500°C begins to form finely dispersed stable austenite, reaching a maximum around 610°C. This stabilized austenite has good toughness even at low temperatures and does not later transform into martensite. cool down. Conversely, at temperatures above A1 (e.g. 620°C), some austenite becomes unstable and transforms into martensite after cooling from temperatures below Ms. This behavior requires further tempering to avoid stress conditions that can lead to quench cracking and stress corrosion.
Applications include turbine parts, propeller shafting, shafting, piston rods and hydropower plant equipment, compressors, pumps, turbines, oil and gas industries, turbine subassemblies, nuts and bolts, shafts, pins, pistons, spindles, crankshafts, In chemical, energy, marine, shipbuilding, aviation/cryogenic industries.
