08X17T aisi430Ti, 08X17 tp430 steel foil, sheet, strip

Production

Ferritic nickel-free stainless steel stabilized with titanium 08X17T (AISI 430 Ti) for general use has a balanced chemical composition, high corrosion resistance, scale resistance at temperatures up to 850 ° C resistance to intergranular corrosion. This steel is classified as heat resistant.

Percentage composition

The presence of manganese and titanium, combined with low carbon content, gives the steel high ductility and toughness properties comparable to those of nickel containing grades (304) and also predetermines a higher structural stability during heating and welding. This steel combines high strength characteristics with good plastic deformability. Stabilized structure of titanium and the low concentration of carbon in the steel provides it excellent weldability, the lack of susceptibility of welded joints to the processes of intergranular corrosion (active carbide formation begins to occur only at a temperature above 1000 ° C). The steel is insensitive to intergranular corrosion cracking within the temperature range of 500-800 °C, and it is much less sensitive to chloride cracking under load.

Technical characteristics

The 08Cr17T steel grade is similar to the domestic 12Cr17 steel grade. But the low concentration of carbon in steel at the level of 0,020-0,035% ensures at elevated temperatures the absence of susceptibility to intergranular corrosion (intensive carbide formation begins at temperatures above 1000 ° C), in addition, it provides excellent weldability. In this regard, the alloy 08X17T on its performance characteristics is an improved analogue, which is recommended as a substitute for steel 12X18H10T, 12X18H9T (GOST 5632-72). The corrosion resistance of the steel in many environments corresponds to the resistance of austenitic steel grade 12Х18Н10Т. Unlike 18Cr-10Ni nickel-containing austenitic steels, chromium low-carbon ferritic steels are resistant in sulfur-containing media. That is why products made of AISI 430 Ti steel (wire mesh , etc.) may be used in pumping systems of oil, gas, clean oil products and hydrocarbons, in technological installations of oil refining and gas processing. Individual tests for corrosion resistance under temperature, loading in contact with process media, duration of continuous operation, aggressive effects of disinfectant and/or cleaning solutions and other specific conditions are decisive in the selection of steel.

Corrosion resistance

This steel has the added advantage of being insensitive to intergranular corrosion cracking within the temperature range of 500-800°C, and is also less sensitive to chloride cracking than nickel austenitic grades. Because of its low coefficient of thermal expansion, the use of this steel is optimal for products that experience temperature fluctuations, and its high thermal conductivity predetermines its merits for use in heat transfer applications. Having relatively low thermal inertia (specific heat capacity) AISI 430 Ti steel is capable of faster heating up and cooling down, which makes it possible to avoid inertial overheating.

AISI 430 Ti steel is widely used in industries such as:

-automotive construction;

The use of economically alloyed nickel-free stainless steels (i.e. 430 analogues) in food and processing industry is regulated by standards and other regulatory documents. The main GOST 5632"stainless steel" also regulates the use of ferritic chromium steel grades 08X17T and 12X17 as a substitute for chromium-nickel austenitic steels of the type 12X18H10T and 12X18H9T, including for food processing equipment, production of kitchen utensils and household items.

Steel 08Cr17T (AISI 430 Ti) can be used in manufacturing technological equipment that is used in various stages of food production (hygienic treatment or cleaning of raw materials, equipment and products, separation and sorting of products, grinding, mixing, packing and packaging, heat treatment, transportation, etc.). On the basis of numerous references in the literature, ferritic steels such as AISI 430 Ti can be used in the manufacture of apparatus and machine parts for the wine industry. Steels of this type are approved for use in direct contact with wine, must, cognac alcohol, as well as the products of the processing of wine waste , etc. It is allowed to use these steels (08Cr17T) for the production of equipment used in the dairy and meat industries in the temperature range 30-140°C.

Since chromium steels have a low coefficient of thermal expansion and higher thermal conductivity than austenitic nickel-containing steels, it is an advantage for their application (including rolled tubular products) in heat exchange applications such as cooling towers , etc. The low coefficient of thermal expansion provides the most reliable fitting and accelerated heat transfer in the cooling system of food tanks (system with cooling water, glycol and other cooling media). Piping and welded structures made of chromium steels change dimensions much less with temperature fluctuations, which provides a reduction in fatigue destructive loads with temperature fluctuations, preventing possible leaks from various hydraulic connections.

All steels of this series (400), including AISI 430 Ti, can be used not only as a substitute for the nickel containing grades, but far surpassing them in some properties, and are irreplaceable in the production of food industry equipment. AISI 430 Ti fully complies with sanitary and epidemiological state norms and regulations, and is very perspective in machinery production for different food industry branches: meat industry, fat and oil industry, bakery, alcoholic beverage, beer and soft drinks industry, confectionary, alcoholic beverages industry and others. High corrosion resistance of steel AISI 430 Ti is characterized by low carbon content and high chrome content (16-18%).

Gas medium

This steel has proved itself as a reliable material in gas environment, which is created during combustion of different fuels. It is used in the manufacture of pipes and casings for recirculation, neutralization, exhaust gas collection and exhaust gas collection systems. Complex high-temperature catalytic oxidation-reduction reactions and aggressive gas environments predetermine the indispensable use of corrosion-resistant economically alloyed steel AISI 430 Ti as a construction material for manufacturing exhaust systems, furnace and other related equipment (chimneys, exhaust ducts, etc .). Such media may contain products of incomplete combustion (hydrocarbons, carbon monoxide, nitrogen oxides, hydrogen sulfide, sulfur dioxide, etc .) and complete combustion (water vapor, carbon dioxide, nitrogen, etc.).

Time resistance to load

Heat treatment

Sheet, strip (foil) 08X17T, AISI 430 Ti is not hardened by heat treatment and has a good resistance to scale formation, while retaining its useful mechanical properties to high temperatures.

Welding

AISI 430 Ti is perfectly weldable by all known methods subject to passivation, pickling/purification after welding without loss of corrosion properties in the welds. For optimum use of inert gas arc welding, it is necessary to observe the minimum energy input in welding the seam. Welding "from above" (i.e., if the surface to be welded is below the welding tool) is recommended. In the form of filler material can be used austenitic wire Sv-07H25H13, 309L, Sv-08H25H13BTU etc. You can also use electrodes or filler wire with chromium ferritic steel base AISI 430 Ti. In order to guarantee adequate corrosion resistance, it is necessary to remove scale and discolouration by pickling or machining with stainless steel brushes and passivate with a cold solution (10-20%) of nitric acid. Then you need a thorough rinse in cold water and dry.
