Composition and properties
In all of its physical and mechanical characteristics of steel AISI 441 (1.4509) is a heat-resistant steel, which has high ability to resist high temperature corrosion. To this end, in the composition of the steel includes titanium and niobium chemical elements for dual stabilization of the microstructure of steel. In accordance with the standard ASTM (USA), AISI 441 (1.4509) includes:
|Protsentnoy content||Not higher than 0.03||Less than 1.0||Less than 1.0||0,1…0,6||0,3…1,0||17,5 18,5…||the rest|
The composition of the steel are such metallurgical impurities, such as sulfur (in the maximum percentage content of 0.015%), and phosphorus (0.04%). In the European standards UNS 43940 additionally slight content of nitrogen that is determined by the conditions of melting (regular, or vacuum-arc furnace). Similar chemical makeup has melted by the European producers of steel X2CrTiNb18. In Russia, this steel grade is not possible. Efficiency steel AISI 441 (1.4509) is determined by its very high corrosion resistance, which applies to all high-temperature chemically aggressive substances, no matter in what physical States they exist. The durability and strength of steel saves up to operating temperatures of 850…9500 C. In this case fully retains its strength and hardness, which are provided by the presence in the surface layers of carbides and nitrides of chromium. Due to the increased ability steel AISI 441 (1.4509) to the weldability of sheet and strip can be made complicated spatial structure without loss of strength in bending and in tension.
Sheet and strip from the examined steel can be easily processed by cutting and pressure, since the deformation hardening of the material is negligible. When punching of the tape may conduct transactions hoods and flexible, and due to the presence of sulfur increases the stability of holding of the separation of transitions stamping including high speed. Steel can be subjected to pre-and in-process annealing, after which it increases machinability on machine tools. For high annealing temperature soaking of metal in an oven set no higher than 700…7500 C, and subsequent cooling of the sheet metal produced on the air. For material handling on machine tools it is advisable to use a tool made of high speed steels.
Sheet and strip in stainless steel AISI 441 (1.4509) is used for the production of body parts of installations which are subject to active pitting corrosion, damaged surface of the metal. It is the housing of elevators, frames, conveyors, chemical units and other products, which are experiencing significant changes in mechanical stress, the load from the frictional forces and high temperatures.
