Heat Treating 304 Stainless Steel Tubing

Heat Treating 304 Stainless Steel Tubing,SS welding tube Bright Annealed

GANYEAH provides heat exchanger and condenser tubes with an outside diameter of 1/2" up to 4". We deliver lengths up to 22 meters of both welded and seamless steel types, such as carbon alloy, nickel alloy, titanium, stainless steel and copper alloys.

Alloys 304 (S30400) and 304L (S30403) stainless steels are variations of the 18 percent chromium – 8 percent nickel austenitic alloy, the most familiar and most frequently used alloy in the stainless steel family.

High strength, excellent corrosion resistance and minimized carbon content make Alloy 304 and 304L Stainless Steels useful for applications where welding is required. Uses include architectural mouldings and trim, welded components of chemical, textile, paper, pharmaceutical and chemical industry processing equipment.

Other advantages are its resistance to oxidation, excellent formability, ease of fabrication and cleaning, excellent strength to weight ratio and good toughness at cryogenic temperatures.

For severely corrosive environments,the lower content of Type 304L is preferred because of its greater immunity to intergranular corrosion.

All tubing is produced with the most advanced Hydrogen Bright Annealing units and weld bead cold working equipment. Only approved raw material suppliers are used that provide uniform wall thickness, Rockwell hardness, strength and elongation. The work cells are equipped with precise roll form tooling, regularly scheduled laser alignment and in-line eddy current testers with automatically programmed cut-out saws. This provides tubes that are produced to the tightest OD, ovality, straightness and length tolerances along with a superior weld condition.
