Sheet, strip 12x17

Sheet, strip 12x17

Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a sheet and tape, which are made of stainless steel grade 12X17. The supplier guarantees timely delivery of metal products to any address specified by the customer.

Technical specifications

Stainless steel 12X17 refers to corrosion-resistant and heat-resistant steels of the ferritic class. These properties are stored up to temperatures of 800… 850 0 С (when temperatures in the heated air are used, temperatures of up to 900 ° C are allowed for a short time). The steel has chemical resistance to the solutions of most acids and their salts, and products made from this steel can be used in the marine environment.

Urgency of application

Typical products made of 12Kh17 steel are working parts of food industry equipment and chemical industries operated at high temperatures: shells of heat exchangers, vessels for storing aggressive high-temperature liquids, food utensils, household kitchen appliances. Deliveries of steel 12X17 are produced in the annealed condition.

Chemical composition

The composition of steel 12X17, in accordance with the technical requirements of GOST 5632−81, includes the following elements (iron — base):

Carbon — not more than 0.12%;

Chrome — 16… 18%;

Manganese — no more than 0.8%;

Silicon — no more than 0.8%;

Phosphorus — not more than 0.025%;

Sulfur — no more than 0,035%.

Physical and mechanical properties

Density, kg / m 3 — 7720;

Melting point, 0 С -1500;

The coefficient of thermal conductivity, in the temperature range 20… 100 0 С, W / Mgrad — 24;

Specific heat capacity, J / kggrad — 462;

Modulus of elasticity, GPa — 232;

The coefficient of thermal expansion in the temperature range 20… 100 0 С, μm / deg — 10,4;

The limit of time resistance, MPa — 400… 490;

Yield strength, MPa — 160… 240;

Hardness according to Brinell, HB, not more than — 197;

Relative elongation at tension,% — not less than 50.

Technological features of processing and assortment

Stainless steel 12X17 is available in a wide range of rolling profiles, cold and hot rolled. At temperatures above 480 ° C, steel is prone to temper brittleness. Weldability of steel is limited: if necessary, use manual arc welding, or welding in a stream of argon, with the required subsequent annealing. The optimum range of forging temperatures is 900… 1240 0 С.

Supplier — AvekGlob company — offers to buy sheet or tape, which are made of stainless steel 12X17 at a price formed on the basis of European and world standards of production. Buy these products can be wholesale and retail. For regular customers, there is a flexible system of discounts.
