DIN 1626 Grade USt 37.0 normalized or normalized formed (+N)
DIN 1626 Grade USt 37.0 normalized or normalized formed (+N) introduction
Welded steel tubes made of USt 37.0 are used in the mechanical engineering, vessel construction, line building and apparatus construction.
The permitted working temperature and the allowed operating pressure are defined in subject to the inspection certificate:
outer diameter: 660 mm
allowed operating pressure [bar]: 16
allowed operating pressure [°C]: max. 300
for delivery with certificate: DIN 50049-2.2
outer diameter: all
allowed operating pressure [bar]: 160
allowed operating pressure [°C]: max. 300
for delivery with certificate: DIN 50049-3.1 A or B or C
Other application limits possible by other technical regulations like TRD, TRB, AD-Merkblätter.
The weldability is given for gas welding, arc welding, flash welding, electrical pressure welding and gas pressure welding.
Equivalent material: DIN St37-2, DIN 1.0253, JIS STPG370, JIS STPY400, EN 1.0253
