Unalloyed steel can also be used as a metallic material for those parts of the apparatus which are less severely stressed.

Plain steel (ST 37) and copper were studied.

Suitable steels include e.g. alloy steel, austenitic steel or unalloyed steel.

Both weights are made of solid iron (unalloyed steel).

The procedure is very inexpensive, and mild steel can be excellently cut with fine jet plasma.

In this form weathering structural steel displays higher resistance to atmospheric corrosion than unalloyed steel.

Three carefully pretreated and weighed strips of metal (unalloyed steel, 80×15×1 mm) were suspended in a 1 liter vessel containing 800 ml of test water, 50 ml of buffer solution and a predetermined quantity of a benzoyl alanine of the invention (formula I) and left therein for 3 hours at room temperature.

Unalloyed steel can be used in 68 to 99% sulfuric acids up to 70° C., although erosion rates of up to 1.3 mm/a can be expected (G. Nelson, Corrosion Data Survey, Shell Development Co., San Francisco, 1950, pp. ZT-102A).

However, when radiator antifreezes are used, it is absolutely necessary to add corrosion inhibitors since the glycol/water mixtures obtained as a cooling medium have a greater tendency than pure water to corrode the materials used in the cooling system, for example cast iron, unalloyed steel, aluminum, copper or brass.

Carbon steel means a non-alloy steel which, except for permissible admixtures, does not contain any special alloy additives except carbon.

A composite multilayer material comprising a substrate layer of steel and at least one functional layer of bearing metal applied, thereto, wherein the substrate is an unalloyed or low-alloy steel with a C content <0.35% (wt/wt) and comprises a surface remote from the functional layer(s), wherein at least in parts of the remote surface, the steel substrate exhibits a hardness greater by the factor 1.5 or more than at a depth corresponding to approximately 0.1 times the thickness of the steel substrate, wherein the hardness is measured as Vickers hardness HV 0.01 and the depth or thickness, starting at the remote surface with increased hardness, is determined orthogonally in the direction of the functional layer(s).

A method according to claims 28, wherein the heat treatment is carried out on unalloyed steel with a carbon content of from 0.03 to 0.06 wt %.

Suitable materials of construction for the reaction vessel are all sufficiently inert materials such as, for example, unalloyed steel, nickel, Hastelloy, and also glass.

The Material-Prüfung Anstalt, Stuttgart, has studied a carbon steel, a stainless steel very similar to those studied by the CSM, a Cr-Mo-V steel and a Ni-Cr-Mo-V steel.

Within the limits of the scatter for the creep tests the results for the two similar materials - carbon steel and stainless steel - agree reasonably well.

Stainless steel thus has to be used for the high-temperature components of the installation, whereas the low-temperature components (40°C) can be manufactured from carbon steel.

Non-alloyed steel may be used in 68-99% strength sulphuric acids at up to 70° C., although corrosion rates of up to 1.3 mm/year must be expected (G. Nelson, Corrosion Data Survey, Shell Development Co., San Francisco, 1950, p. ZT-102A).

In that connection, it should be borne in mind that the injection lines which always have to have a plurality of curves in going from the injection pump to the associated injection nozzle on the operating cylinder of the internal combustion engine are only made of soft, non-alloyed, low-strength steel, and even local hardening of that material at the connecting fittings formed thereon cannot be permitted. If it were relatively hard, the material of the injection line, extending from the hardened connecting fitting, could not experience adequate resilient flexing in relation to the inevitable vibrations of the injection line when the internal combustion engine is running, so that those connecting locations could easily constitute the sources of vibration fractures.

Three carefully pretreated and weighed test strips (unalloyed steel, 80×15×1 mm) were suspended in a 1 liter vessel containing 800 ml of test water, 50 ml of buffer solution and a predetermined quantity of the inhibitor to be tested and left therein for 3 hours at room temperature/80 r.p.m.

The method according to claim 8, wherein an AlSi alloy and a non-alloy steel are used as materials, and/or the mix ratio is 60 to 70:30 to 40.

The corrosiveness categories in accordance with DIN EN ISO 12944, based on the mass loss per unit area or on the thickness reduction after the first year of ambient storage, are defined as follows for unalloyed steel and for zinc: (low corrosivity): unalloyed steel:

The material can also be selected from the group consisting of aluminum, magnesium or the alloys thereof, iron, unalloyed steel, stainless steel, nickel-based alloys (Hastelloy), titanium or titanium alloys, depending on the pollutants to be adsorbed on the activated carbon fibers.

By comparison, unalloyed steel has a heat conductivity of about 50 W/mK, while aluminum has a heat conductivity of above 200 W/mK and copper has a heat conductivity of above 300 W/mK.

In particular, particularly good properties are expected if an AlSi alloy and a non-alloy steel are combined as materials, and/or the mix ratio between two different materials is 60 to 70:30 to 40.

Stainless steel, for example, non-alloyed but surface-treated steel for better thermal conductivity, or also copper and copper alloys may come into consideration as materials for manufacturing washer 8, which may, for instance, be drawn as wire and then shaped.

If mild steel or stainless steel is to be welded, it need not be cleaned therefore, direct current electrode negative TIG welding can be used.

According to the state of the art, hardened high-alloy and unalloyed steel, as well as stellites, cast nickel, various white cast iron and cast iron materials such as, for example, Ni-Hard and gray cast iron are used in the manufacture of running gear seals.
