EN 1.4550 (GX5CrNiMo19-11-2) Stainless Steel
EN 1.4550 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 1.4550 is the EN numeric designation for this material. GX5CrNiMo19-11-2 is the EN chemical designation. It has a moderately low corrosion resistance among wrought austenitic stainless steels. In addition, it has a moderately high boiling point and can have a moderately high tensile strength.
The properties of EN 1.4550 stainless steel include two common variations. This page shows summary ranges across both of them.
Composition
The graph bars on the material properties cards further below compare EN 1.4550 stainless steel to: wrought austenitic stainless steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means its 50% of the highest, and so on.
Corrosion Resistance
EN 1.4550 stainless steel has moderate resistance to corrosion in comparison to other steels.
Boiling Point
EN 1.4550 stainless steel has a moderately high boiling point of 3287°C (5949°F).
Tensile Strength
EN 1.4550 stainless steel has a moderately high tensile strength among wrought austenitic stainless steels. In addition, it has a moderately high melting temperate as well.
The term ‘wrought’ referes to the working of metal into wire and sheet metal into various shapes and size, different from the normal use of casting in which molten metal is poured into a mold.
Applications
EN 1.4550 stainless steel is used in a variety of industries and applications including:
Architecture – EN 1.4550 stainless steel is frequently used as a cladding in modern façades or to make metal frames.
Chemical – EN 1.4550 stainless steel is commonly used in the production of heat exchangers and equipment used to produce high quality pharmaceuticals.
Aviation – EN 1.4550 stainless steel is used in a range of high-performance components such as engines and military equipment.
Medical – EN 1.4550 stainless steel is used in medical technology for implants and surgical instruments.
Foods – EN 1.4550 stainless steel is used for components and equipment in the food industry.
Oil and Gas – EN 1.4550 stainless steel is used for pipes, valves, pumps and other components used in the oil and gas industry.
Due to its hardness, high strength, durability, and resistance to corrosion and chemicals, EN 1.4550 stainless steel is an ideal material for applications where strength, corrosion resistance and safety are required. It is also used in pieces that are exposed to moisture, high pressure and wear, or those that need to have an attractive finish.
