Heat-resistant steel AISI 314 / EN 1.4841

stainless Steel AISI 314 / 1.4841 EN / 20KH25N20S2

Heat-resistant stainless steel AISI 314 is intended for use in corrosive environments at high temperatures (up to 1150 Celsius degrees). Characterized by high strength and resistance to flow. Corrosion resistant surface, plane and point types. Features Stainless steel AISI 314 is composed of chrome-Nickel additives. It provides high resistance to oxidative processes during all operating conditions. In a wide temperature range, the alloy retains its physical parameters. This stainless steel (price in our catalogue is one of the most affordable) has a high plasticity, easy to weld using various methods. Please note that seam requires additional processing. In connection with tendency to scale formation at the critical temperature, the alloy is tested at the factory to an extra hardening procedure. Use Steel of this brand are widely used. It is used in various industries and in construction. It is made of the equipment for pyrolysis and methanol conversion, high temperature of the combustion chamber, the conveyor components, high pressure lines. Resistance to aggressive environments has allowed steel to become one of the most sought after materials in the petrochemical industry. Higher resistance to corrosion determined its application in marine shipbuilding. Chemical composition of steel EN 1.4841
