Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Alloy Steel T1 Tubes, which is preferable, but not necessary, that the alloy be in the solution – annealed condition when welded. Annealing at temperatures lower than the solution heat – treating may cause precipitation of secondary phases, which may affect the strength and ductility of these Alloy Steel T1 Seamless Tubes. The web should be thinned down to about one – third the web – thickness of a standard drill and thus better finishes of Alloy Steel T1 Welded Tubes can be obtained by increasing the speed and decreasing the feed.

Automatic screw machines are not recommended for these Alloy Steel T1 EFW Tubes because speeds are generally excessive and carbide – tipped tools will not hold up. Sulphur – base cutting fluid should be used for machining Alloy Steel T1 ERW Tubes, where all traces of cutting fluid should be removed prior to heat-treatment or high temperature service. These Alloy Steel T1 Round Tubes are indicative only of the results obtained in such tests and should not be considered as guaranteed maximums or minimums.
Alloy Steel T1 Square Tubes must be tested under actual service conditions to determine their suitability for a particular purpose. Furnace trays in these Alloy Steel T1 Rectangular Tubes, which used to support heavy loads, have been exposed to temperatures up to 2300 Degree F in an oxidizing atmosphere without bending or warping.
