Mark AISI 430 Ti
It is nickel-free ferritic stainless steel of general purpose stabilized titanium. It has a balanced chemical composition; high corrosion resistance, resistance to intergranular corrosion. It operated at temperatures up to 850 ° C. It is classified as heat-resistant.

The presence of aluminum and titanium in combination with a low percentage of carbon, leading to high ductility and strength, a similar nickel-stamps (304). When heating and welding it stabilizes the structure, protecting welds from intergranular corrosion. Active formation of carbide only begins at t ° to 1000 ° C. Compared with austenitic nickel stamps, this steel is not sensitive to intergranular corrosion at 500−800 ° C, and much less sensitive to the chloride load cracking.
The corrosion resistance of AISI 430 Ti steel is similar 12X18H10T, 08H17. Unlike nickel austenitic steels, low carbon chromium ferritic steel resistant to sulfur-containing environments. In this connection, wire mesh grade AISI 430 Ti oil used in pumping systems, gas, petroleum, gas processing plants and oil. The carbon content provides 0,02−0,035% at elevated temperatures, lack of propensity to intergranular corrosion resistance and excellent weldability. This grade according to GOST 5632−72 in performance is a substitute for steel 12X18H10T, 12X18H9T. It is insensitive to intergranular corrosion failure at t ° 500−800 ° C, is much less sensitive to chloride stress cracking.
Minimum thermal expansion coefficient makes the use of the steel at low temperature differences, for example, heat transfer systems. With a relatively low specific heat, AISI 430 Ti steel is able to warm and cool quickly, making it possible to avoid possible overheating of inertia.

Steel AISI 430 Ti is stable in gaseous media, fuel combustion. Such media contain products of incomplete combustion (CO, NO, H 2 S, SO) and the complete combustion (steam, CO 2, NO 2, N 2, SO 2 and so on. D.). AISI 430 is used for recirculation systems capture and neutralization of exhaust gases. Resistance to aggressive gas environments cause the use of steel AISI 430 Ti in the manufacture of exhaust systems, heating equipment — exhaust systems, chimneys. Chromium steel having a minimum thermal expansion coefficient and enhanced thermal conductivity compared to austenitic nickel stamps. This predetermines their use in heat exchange systems such as cooling gradilni. Low thermal expansion coefficient of the Fitting fixation ensures reliable and rapid heat transfer during the cooling of food tanks (water, glycol, or similar fluids). Piping and welding pieces of chromium steels have minimal dimensional changes with temperature variation that reduces destructive fatigue loads at temperature drop preventing unintended leakage of the hydraulic connections.
Use in food industry
Ferritic steel similar to AISI 430 Ti popular in the wine industry. They are approved for use in contact with the wine, wort, cognac alcohol, as well as others. Winemaking products. Allowed the use of such steels (08H17T) for the production of equipment used in the meat-packing industry at temperatures up to 140 ° C.
Steel AISI 430 Ti in demand in the production of food processing equipment manufacturing (hygienic processing of raw materials, equipment and products, separation, mixing, sorting, grinding, packaging, heat treatment, transportation). All this became the 400 series, in Vol. H. Of AISI 430 Ti can not only replace the nickel grade, but significantly exceed them in a number of properties, particularly for the food industry.
AISI 430 Ti meets state standards and SNIP is very promising in the production of equipment for processing and food industry: meat, fat, baking, alcohol, beer and soft drinks, confectionery, alcoholic beverage, and others.
— Transport machinery;
— Civil engineering and design;
— Manufacture of kitchen appliances, tableware;
— Manufacture of sinks, parts washing machines, sinks, trays and reels for dishwashers
— Hardware production.
The use of nickel-free economically-alloyed stainless steels (430 analogs) in the processing and food industries regulated by the relevant regulations.
Effect of high temperature
AISI 430 Ti is not hardened by quenching and resistance to the formation of dross is retained up to 850 ° C temperature. It can be operated in an aggressive environment not subject to elevated temperatures.

Welded by any methods without losing corrosion resistance welding in places subject to a post-weld treatment: a passivation etching / cleaning. Arc welding in an inert gas atmosphere requires minimal power consumption. Welded surface located under the welding tool. Wire-07Kh25N13 Savanoriu Str, St.-08H25N13BTYU, 309L or AISI 430 Ti serves as filler material. After welding, remove scale, process annealing color space etching or brushes made of stainless steel and cold propassivirovat 10−20% HNO 3 solution, followed by washing and drying.
