Composition and properties
Stainless steel, which is produced in accordance with the norms of ASTM and AISI, has the following chemical composition:
|Content, %||0,10 0,17…||To 1||To 1.5||Up to 0,15…0,35||To 0.040||15,5 17,5…||0,20 0,60…|
Steel has foreign counterparts. A similar product, which is produced by the European metal producers according to EN 10088−3, received the designation steel Х14СгМоЅ17 in Russia and the CIS analogues of this steel no.
For comparison table of chemical composition of steel Х14СгМоЅ17:
|Content, %||0,10 0,17…||To 1||To 1.5||Up to 0,15…0,35||To 0.040||15,0 17,0…||0,30 0,80…|
Pipe rolling of corrosion-resistant steel 1.4104 comes with the following physico-mechanical parameters — the density of 7.7 g/cm3, yield strength up to 750 MPa, a hardness of 112…120 HB elongation a 15…22% (smaller values correspond to larger diameter pipes). Steel can be supplied to consumers in both hot — and cold-rolled state, thus may be pre-annealing. This type of heat treatment: heating to 750…8200 C, With subsequent cooling first in the oven, and then outdoors. After ezuprechnaya processing the steel can be cold plastic deformation.
Hot rolled pipe rolled steel is used when considering the installation of pipelines that produce pumping chemically aggressive environments at elevated up to 350…4000 C temperatures. Parts of steel 1.4104 are also used in the manufacture of tubular elements powerful compressor units, which operate in air with high humidity, as well as in the blower units of metallurgical equipment.
For the production of complex spatial structures pipe rolling was subjected to repeated annealing, which increases the ductility and allows to produce defect-free bending of the product (in this case the impact strength of the tubular semi-finished product must be at least 43 kJ/cm3). With the increase in the percentage content of molybdenum in the steel its strength after the deformation increases.
Buy pipe stainless steel 1.4104, taking advantage of the great offers of the company Electrocentury-steel convenient and expedient. Delivery of products is conducted only after a thorough quality control of the final tube rolling, which is confirmed by corresponding certificates of quality.
