Quality and Mechanical Tests for Stainless Steel Round Pipes & Tubes as per ASTM standards

Mechanical Properties :
Tensile Strength, MPa	Yield Strength, MPa	Elongation, %
415 min	205 min	30 min

From the receipt of raw materials to the final inspection of the finished products – we do everything we can to ensure our customers receive only the very best quality. Of course, all tubes of a non-destructive and / or destructive testing may be subjected. We have the HP-0 approval by the TÜV and also meet many other quality requirements. Final Inspection:- IGC Test Dimensions Surface, Physical Testing, Grade Check, Product Analysis.

Heat Treatment (Annealing) for Stainless Steel Round Pipes & Tubes as per ASTM standards

304/304L is not hardenable by heat treatment. Cold working increases tensile strength and hardness. Annealing range is between 1850° and 2050°F. Cool rapidly. Water should be used for heavier sections; air for lighter sections. The stress relieving range is between 400° and 750°F

Surface Finishes for Stainless Steel Round Pipes & Tubes as per ASTM standards

Galvanized, Polished. Other finishes available upon request.

Flattening Test for Stainless Steel Round Pipes & Tubes as per ASTM standards

For material heat treated in a continuous furnace flattening tests shall be made on a sufficient number of pipes to constitute 5 % of the lot, but in no case less than 2 lengths of pipe.

Markings for Stainless Steel Round Pipes & Tubes as per ASTM standards

Bright annealed tubing is line–stenciled with OD, wall, ASTM specifications, size, grade, heat number, production date and time. OD polished tube is marked on one end of each tube with a removable label stating ASTM specification, manufacturer, grade and heat number. Continuous line stencil available on request.
