Scopes

1.4571 is a stainless, austenitic chromium-nickel-molybdenum steel stabilized with titanium. When high temperature strengths are required, the 1.4571 is used as an alternative than for example the material 1.4404.

It is characterized by its good corrosion resistance in most natural waters (urban and industrial), provided that the concentrations of chloride, hydrochloric and hydrochloric acid are not too high.

Intercrystalline corrosion resistance is superior to titanium unstabilized steels because the titanium addition prevents the precipitation of chromium carbides in the grain boundaries.

After welding, no heat treatment is required due to the low carbon content.

1.4571 is also known under the classification AISI 316Ti.

 

Application areas

This steel is used in apparatus construction and shipbuilding, in the construction industry, the chemical industry, in mechanical engineering, in the medical industry and in the pharmaceutical industry.

In the food industry, 1.4571 is also used for the transport and storage of food.

Forging: During forging, preheating takes place between 1.150°C and 1.180°C. Thereafter, the material can be forged at 1.180°C and 950°C. The subsequent cooling takes place in water.

Welding: 1.4571 can be welded by all common methods. No welding filler is required for this and no heat treatment is necessary after welding. A temperature of 200°C should not exceed the interpass temperature.

Corrosion resistance: At low to medium concentration of chlorides, salts and hydrochloric acid as well as organic acids the 1.4571 shows good corrosion resistance. Even after welding, there is resistance to intergranular corrosion.

Machining: Tool wear during machining is increased by alloying titanium.

Advantages of saw cut

The processing with the saw is a mechanical processing of the material, which results in a significantly lower unintended deformation and increased hardness for the existing structure, such as the thermal cutting.

Thus, the machined workpiece has a homogeneous structure even at the edge, which does not change in the continuation of the material.
This circumstance allows immediate finishing of the workpiece with milling or drilling . So it is not necessary to anneal the material or make a similar operation beforehand.
