Wire, round, rod 03х17н14м2 - 1.4404 - aisi 316L

Basic information

Stainless steel grade 316L is an improved version of AISI 316, with additional content consisting of molybdenum and a higher Nickel content. This gives the opportunity to increase the resistance of steel to corrosion. AISI 316 L has excellent qualities for forming and excellent welding characteristics. This composition gives the opportunity to significantly increase steel corrosion resistance in most aggressive hired. The presence of molybdenum in AISI 316 L protects from pitting corrosion crevice in seawater environment chloride and acetic acid vapors in the polluted atmosphere.

AISI 316 L compared to the AISI 304 has the best creep resistance, has greater strength at high temperature. Also in sub-zero temperatures, the steel does not lose the excellent mechanical, corrosion properties. This grade is used when there is a risk of corrosion in heat-affected zones of the weld. Steel AISI 316 L, stabilized with titanium, is used in the temperature range 550−800°C for long time.


Such a unique outstanding properties of steel, such as corrosion resistance, high processability, excellent mechanical properties enable the Marche AISI 316 L have a wide range of applications in many industries. It may be chemical, pharmaceutical industry, oil industry, mechanical engineering, heat exchangers, processing, food industry, etc.

Treatment of thermal

The beginning of forging temperature .1150 — 1200 °C, the end. t°.950°C. the Period of time estimated to obtain a homogeneous heating of stainless steels longer than carbon-12. Relief (or release) method of autogene without showing deposition of carbide is in a temperature range of 450−800o C. thus, the departure from microlimano possible corrosion. Gradual lowering of the temperature necessary to safeguard the allocation of carbon. The annealing is carried out at t°1050 — 1150 °C cooling and the sharp intake of cool air, providing maximum ductility of the steel.

Treatment cold

Due to its strength, this steel finds a variety of use. Typical operations include bending, forming by stretching, rotating and deep hood. At the time of molding using the same tools as for carbon steels. In this case, it will take much more effort is approximately 1.5−2 times. This makes babout thegreater degree of hardening when forming austenitic steel, but in certain cases may also serve as a negative factor.

Hood Rotogravure

During deep drawing of the workpiece to the press was not subjected to «braking», and give freely to pass in the instruments in practice, however, this happens not so often. For example, always takes place forming with stretching in the manufacture of the cookware. The material, which is subjected to deep drawing must have when forming a low degree of hardening, i.e. to be stable at the maximum, and the rate of Md30 (N) have to be «in the red». For kitchens stainless steel appliances are typically used so-called sub-tests of stainless steel stock as in the production of pots by deep drawing. In flow-forming machine rotary extractor means forming with the turning.

Forming, stretching

In the period of forming, stretching is subjected to a preset «inhibition». Its walls become very thin during forming, to avoid a gap, preferably of steel to provide the characteristics of high strengthening.
