03Х17Н14М3- 1.4404 – aisi 316L tube A312 Tp316L Seamless pipes
Pipe 03Х17Н14М3 is a seamless rolled pipe of a round profile, related to heat-resistant acid-resistant rolled metal, manufactured according to GOST 9941-81.
03Х17Н14М3 is used for the production of steel structures and units for operation in highly aggressive environments at temperatures down to -196°С.
What is 03Х17Н14М3
03 means the percentage of carbon 0.03%. “X17” means the presence of chromium in the alloy in the amount of 17%. “H14” means the presence of nickel in the amount of 14%. “M3” means the presence of molybdenum – 3.0%.
The raw material for production is chromium-nickel complex alloy steel with the addition of molybdenum. The chemical composition of the metal is strictly regulated by GOST 5632-72. Chromium and nickel together with molybdenum create an alloy that can withstand environmental aggression.
Application of pipes 03Х17Н14М3
The main purpose of the considered rolled pipes of any assortment is the production of components and special-purpose parts. Such elements work for wear and are subject to serious loads in harsh working environments:
- heat exchangers;
- braziers;
- base of chimneys and fireplaces;
- boiler equipment;
- parts of technical equipment operating in sulfuric, phosphorus and salt environments.
steel grades: low-carbon AISI 316L (local analogue is 03Х17Н14М3 steel)
AISI 316 stainless steel Pipes s most widely used in chemical production. Tanks are made from it for storage of substances aggressive in their characteristics, which are acid substances, threatening corrosion for the metal.
Besides, AISI 316 stainless steel pipe is involved in the manufacturing ducts, pipelines, boilers of industrial destination; equipment for use in corrosive environments. For example, in the sea water.
AISI 316 stainless steel pipes are used for the manufacturing pharmaceutical and food equipment, as well in pulp and paper and mining fields.
