  • SS 304 ASTM A312 Seamless Pipe Marking & Packaging

While marking we choose a specific item number as well different color shade to differentiate steel grades. We mark SS 304 ASTM A312 Seamless Pipe as needed with the most suitable & visible marking technique.

We deliver from stock and warehousing as well as directly from the mill.

Packaging is an integral part of the product. It guarantees that the SS 304 ASTM A312 Seamless Pipe is delivered to the customer in the required quality. For smaller orders the size of the SS 304 ASTM A312 Seamless Pipe bundle depends on the no. of Tubes ordered, for larger orders the tubes are packed into individual bundles and in such a way that the maximum weight of 4000kg per bundle is not excedded. Bundle tied down with steel tape. Bundle tied down by steel strap underlaid by tapaten.

We can also provide SS 304 ASTM A312 Seamless Pipe wooden box packing, cardboard boxes, plastic wrapping, using hardened paper with PE meshing (used as protection against mechanical damages of tubes), into tapaten and polyethylene sheet etc.

304 Stainless Steel Pipes and Tubes Corrosion Resistance

Excellent in a wide range of atmospheric environments and many corrosive media. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 600C. Considered resistant to potable water with up to about 200mg/L chlorides at ambient temperatures, reducing to about 150mg/L at 600C.

304 Stainless Steel Pipes and Tubes Heat Resistance

Good oxidation resistance in intermittent service to 8700C and in continuous service to 9250C. Continuous use of 304 in the 425-8600C range is not recommended if subsequent aqueous corrosion resistance is important. Grade 304L is more resistant to carbide precipitation and can be heated into the above temperature range.

Grade 304H has higher strength at elevated temperatures so is often used for structural and pressure-containing applications at temperatures above about 5000C and up to about 8000C. 304H will become sensitised in the temperature range of 425-8600C; this is not a problem for high temperature applications, but will result in reduced aqueous corrosion resistance.

304 Stainless Steel Pipes and Tubes Heat Treatment

Solution Treatment (Annealing) - Heat to 1010-11200C and cool rapidly. These grades cannot be hardened by thermal treatment.
