Product Description

TP321/TP321H/UNSS32100/1.4541/X6CrNiTi1810//SUS321/0Cr18Ni10Ti                        Seamless stainless steel pipe and tube

Product Description

Material Summary

Grade 321 is the grade of choice for applications in the temperature range of up to about 900°C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion.

Grade 321H is a modification of 321 with a higher carbon content, to provide improved high temperature strength.

Used primarily for parts requiring excellent corrosion and strong magnetic properties such as:

• Boiler tubes and casings

• Oil and gas refinery piping

• Radiant superheaters

• High-pressure steam pipes

• Heat exchanger tubes

• Cabin heaters

• Heavy wall-welded equipment

• Aircraft exhaust stacks and collector rings

• Chemical production equipment

Packaging & Shipping

1.generally export packing

   -packed by knitting strips in bundles

2.It is suggested that the pipes OD under 25MM or Less than container shipment are packed by plywood cases, which can protect pipes better.
