AISI 317 stainless steel LMN / EN 1.4439

Steel AISI 317LMN / 1.4439

This product fully conforms to international standard of AISI (AISI). Steel is a complex mixture of their chromium, molybdenum, Nickel alloys, and nitrogen components:

·        improve corrosion resistance;

·        to increase the service life in all operating conditions of the products on the basis of the steel grade;

·        to provide the required ductility.

Steel of this brand is versatile, improved strength and resistance to pitting and surface corrosion.

Purpose and use

AISI 317L can be used in neutral environments and in areas with high concentrations of vapours of acids and alkalis. Increased resistance to the destructive effects of aggressive environments has led to the scope of application of such steel.

It is used for:

·        production of medical equipment and surgical instrument;

·        manufacturing equipment for the food and pharmaceutical industries;

·        construction of load-bearing welded structures;

·        welding wire;

·        the needs of the petrochemical industry and so on.

Features

Steel of this brand successfully resists organic acids, chloride environments, salty sea water. Protective film of insoluble compounds on the steel surface to withstand even brief exposure to concentrated acids.

Steel is "takes" a critical high and low temperature, keeping all its characteristics. Does not cause allergic reactions, do not vaporize volatile harmful substances when heated.
