EN 1.4439 Seamless Stainless Steel Tube Sch40S Sch80S Used In the
chemical
Introduction to products:
EN 1.4439 stainless steel is an austenitic stainless steel
formulated for primary forming into wrought products. Cited
properties are appropriate for the solution annealed (AT)
condition. 1.4439 is the EN numeric designation for this material.
X2CrNiMoN17-13-5 is the EN chemical designation. It is a derivative
and better austenitic variant of the 316 and 317 steel grades,
having higher Nickel, Molybdenum and Nitrogen content, which
significantly increases the product's resistance to pitting and
crevice corrosion in Cl environments.
It has a moderately low electrical conductivity among wrought
austenitic stainless steels. In addition, it has a moderately high
embodied energy and a moderately high base cost.
APPLICATIONS :
Its application in the chemical, energy, cryogenic, petrochemical,
pulp and paper industries as well as in food contact with chlorides
and the effects of high temperatures.
