Technical characteristics
X12CrNiTi18−10 grade relates to austenitic class. It is heat and corrosion resistant. Steel composition: chrome — 17−19%, nickel -9−11%, manganese — 2%. Destination: parts that operate at a temperature of up to 600 °C; vessels and welding devices that work in diluted solutions of acetic, phosphorus, nitric acid, solutions of slats and alkalis etc.; components and parts that can work from cryogenic to a temperature of +600 °С under pressure in corrosive environments. Blocks and parts of pipelines of the main equipment of nuclear reactors with water-type heat carriers.
Percentage composition of alloy:
| Steel | C | Cr | Fe | Ni | Ti | Mn | P | S | Si | Residual elements |
| X12CrNiTi18−10 | ≤0,12 | 17 — 18 | Basis | 9 — 10 | ≤0,8 | ≤2 | ≤0,03 | ≤0,02 | ≤0,8 | ≤0,15 |
Manufacturing process of these pipes relates to technologically-difficult category. Welding includes a processing of seam surface and final heat treatment that gives resistance to high temperatures.
Relevance
Stainless pipe contains no less than 12% of chrome, which gives high resistance to corrosion. This pipe differs with wear resistance, long operational life, strength, resistance to oxidizing, ease of installation. High strength of stainless steel allows decreasing a weight of construction and material consumption. There is a possibility to remelt its scrap and to process it. That is why it is fairly cheap material if to take into account a long period of usage and perfect constantly continuing properties.
Main properties
Heat resistance, long operational life, strength, wear resistance, resistance to different types of corrosion and action of aggressive environments, aesthetically attractive appearance.
Types of products
By destination, pipes can be divided into a few groups: hygienic, structural and pipes applicable in reactors and heat-exchangers. By section type, pipe can be circular and shaped (square, rectangular, oval). Stainless shaped rectangular pipe is the most frequently used in building of objects. Circular pipes can be electric-welded and seamless. Surface can be bright or polished to brilliance.
Application
Vessels and welding devices that work in diluted solutions of acetic, phosphorus, nitric acid, solutions of slats and alkalis. Blocks and parts that can work from cryogenic to a temperature of +600 °С under pressure in corrosive environments. Blocks and parts of pipelines of the main equipment of nuclear reactors with water-type heat carriers. Due to smooth surface without roughness, this pipe is much used in pharmaceutical and food industry. Due to high strength, such pipe can withstand significant pressure differential and high temperature that are unavoidable in boiler, heating, pumping station.
