The company Evek GmbH offers a wide range of stainless steel products (wires, rounds, bars) in stainless steel 1.4104 at a favorable price. At a quite affordable level of prices for these products, the company also provides prompt delivery of rolled products to any location that will be specified by the customer Composition and properties

Corrosion resistant mild steel is produced according to both North American AISI and European EN 10088-3 standards, with the following chemical composition:

Chemical element C Si Mn S P Cr Mo
Percent in steel 0,10...0,17 Up to 1 Up to 1.5 Up to 0.15...0.35 Up to 0.040 15,5...17,5 0,20...0,60

The European analogue of this steel is X14CrMoS17, which has practically the same chemical composition, with somewhat less restrictive tolerances for percentage of manganese. Volumetric rolled stainless steel has such physical and mechanical properties as volumetric density 7.7 g/cm3, tensile strength 750...780 MPa (lower values correspond to bars with enlarged cross-sectional area), hardness after hot rolling not less than 120 HV and relative elongation 20...24%.

Steel grade 1.4104 is rather plastic, therefore it can be rolled both in cold and hot condition. The wire made of this steel is available either cold drawn or drawn (in the latter case the steel strength characteristics are additionally increased by the strain-hardening process).

In the latter case the strain-hardening effect provides an additional 15-20% increase in strength properties.) If necessary the steel is subjected to heat treatment - annealing at 750...8500 С, followed by cooling of rolled products. It initially takes place in the furnace, and ends in calm air.

The presence of molybdenum and chromium promotes the formation of high-strength carbides that increase the resistance of the material to corrosive processes that occur intensively at elevated temperatures. Relatively low carbon content allows various mechanical processing, as well as cold forming, including the use of automated equipment.

Application

Volumetric semi-finished products of this stainless steel are used in the manufacture of various forgings and machine parts, which are intended to be used in corrosive environments and at temperatures up to350-4000 C. Such parts include forged parts of pumps for pumping chemically active media, high resistance fasteners of various designs, moving parts of powerful compressor stations and air blowers, parts of industrial refrigeration equipment , etc.

When it is necessary to manufacture the details of high complexity the steel is intensively hardened that is accompanied by decrease in the indicator of impact strength to 30...35 kJ/cm3. In such cases volumetric rolled steel may be subjected to secondary annealing, during which the structure of the metal becomes finer grained.

Buy volumetric rolled products of corrosion-resistant steel grade 1.4104 from the company Evek GmbH is very profitable, because the supplier always guarantees the required range of supply. To buy products of consistently high quality, confirmed by the appropriate certificate means to ensure the longevity of equipment parts, which will be made of this steel.
