S30400 22mm stainless steel tube Corrosion Resistance Excellent Weldability Tubing
300 series grade stainless steel is manufactured into a range of products including steel tubes,steel pipes and various other products. Both 304 and 316 steel tubes are nickel-based alloys that are easy to maintain, resist corrosion and maintain strength and durability at high temperatures. Determining which grade of steel is best for your application depends on the intended application as well as environmental factors such as temperature or exposure to chloride.
Description:
Austenitic 304/4301 welded precision stainless steel tubing has excellent weldability and is suitable for the full range of conventional welding methods (like MMA, MIG, MAG, TIG, SAW, LBW, or RSW), except gas welding.
304/4301 have about 50% higher thermal expansion and lower heat conductivity compared to carbon steels. This means that larger deformation and higher shrinkage stresses may result from welding.
In thin sections, autogenous welding may be used. In thicker section, the low-carbon grade 4307 is preferred, and to ensure that the weld metal properties (e.g. strength, corrosion resistance) are equivalent to those of the parent metal, matching or slightly over-alloyed fillers should preferably be used. Recommended filler metal is 19 9 L.
Post-weld heat treatment is generally not required. In special cases where there is high risk of stress corrosion cracking or fatigue, stress relief treatment may be considered.
In order to fully restore the corrosion resistance of the weld seam, the weld discoloration should be removed by pickling and passivation.
